Material Challenge 06

[Erklaerbar]

I would love to see people posting some fresh mat and light settings ;)
Heres one for a start:
Its a quite basic setup, but gives some funny fluorescent effect. Since it is light dependent, use it on a separate layer and bake the effect if you want to use it in a scene! You can easily change the glow color by changing the third lights color settings.

and another one:

I like the green blobs! looks really fresh and may be good for illustrations. thanks!

[SpaceMan]

Thanks Erklaerbar

I did a rev of your fluor lights and added them onto your alien mat and got this metal foil like look. Used zb's default texture spectrum and rendered best with shadows and depth on

Do you have the alien mat in golds and browns

[troy1617]

settings and materials like is there anybady out there has any if so please post to this forum thank you!!!!!!!!!!!!!!!

[Blaine91555]

Heres a couple from a current project

[Erklaerbar]

cool, keep them coming ;)

Heres another gold (posted a while ago)

PS: Spaceman, you could try to change the colors in the different shader channels.

[Erklaerbar]

another one, can be used in space scenes or to simulate (sort of) images made by a raster-elektronen-mikroskop (whatever the english word for that may be).

Again one to be baked as light dependant (render with shadows!)

And a cavityshader. It fills space between polygonborders with white. Thus it obviously looks quite different on the various SD levels:

Erklaerbar thanks for the tip- reworked your mat and lights and got the bronzeee like color

[SpaceMan]

Blaine91555 some really cool golds:cool: thanks:tu: - I used your mygold to create a gold texture with grab doc and Erklaerbar's white cs mat - :tu: - the model is froyd's hound ztl here at zbc (zeebled)

[Erklaerbar]

:) cool. Keep experimenting :-) I noticed a glitch in the bronzeshader however, see these little white points? Dont ask me where theyre coming from, but i suspect its something in the Gel shading settings. I noticed them on some own materials too, can be quite a pain to get rid of them :confused: If anyone knows more on how these glitches are created and whats the reason for it i would be very much interested to hear it.

[SpaceMan]

Erklaerbar I do not know what is causing the effect of the specks.

I do like your mats and lights

this image was done with your nanotech mat and your fluor lights

[SpaceMan]

A few things that I would like to get as a mat and light set is a translucent white with gold/bronze/and/or browns AND a translucent blueish white with silver/and/or grays THAT outline the details. Erklaerbar's nanotech mat and flrou lights come close to what I am trying to explaining and the image 1nano might help in explaining


I have been thinking about this for awhile and do not know if zbrush can do it so I have included an image that might explain it better (where one of the ztools is very translucent and the other is the detail ztool)

[Blaine91555]

SpaceMan - I'm not sure I understand but this mat might be helpfull. To get the effect I think you want - change the ambient and cavity colors on shader 4. As posted it is a golden color. Must be rendered on a seperate layer with flatten off in best render with shadows on. For a transparent mat just use the plastic default and set tranparensy to 100 and give it a little reflectivity.

The mat settings are new to me so thanks for working with the information I posted.

The mat that you posted is really cool it is pretty much what I am trying to get.

Now the second part of the question is can/how do you place the transparent mat ztool over a soild ztool of the same model so that the transparent ztool will allow the soild ztool (same model not a different one) be seen through the transparent areas of the transparent ztool. ( some scaling of the transparent ztool might have to be done)

After thinking some more on the golden color I think that it is limited to zbrush's color palette (correct me if I'm wrong) and the only way to get a real golden color (such as in your gold mats) would be to extend the color palette to include some metalic colors.

[Erklaerbar]

Hmm, i never played with transparency at all really because i found it too abstract to work on different layers. I might play around with it when i find time.
In the meantime there is another mat. Sort of dark hence the name:

And a somewhat useless emergency room setup ;)

ZBrush can do this (if I understand you correctly) but you need your two objects on different layers for the transparency to work. You must also switch off Flatten in the Render options. Draw your first object on one layer and Mark it. Create a second layer, switch off the Material option in the Marker palette and all the other options on. Choose your transparent material then click on the marker and your object will be redrawn. You can then use the Gyro to scale. Do a best render to see the effect. (For some materials you may need to switch layers before they update.)

Thanks Marcus for the working work flow and for reading the info from someone who doesn't know the jargon for the mats etc

A few questions:

1 When I tried moving the top layer marker tool the marker tool on the other layer did not move with the top layer marker tool - how do I combine the two into one ztool to place in a comp on the canvas?

2 Does the transparent mat top layer have to be on the top layer or can this be changed to put the transparent mat on the first layer render and then on the second layer maker tool use a different mat.and scale so that the transparent marker tool becomes a glow for the top layer marker tool?

Took a break from the transparent mats and did your work flow with markers with some other mats and got a walking out the shadow effect that I guess could be done to look like walking out of liquid with other types of zmats. Just a show the effect image experiment.

[smileman]

And the refraction, still try but no effect...? :D

[Blaine91555]

SpaceMan -

Here is another mat that might be a little closer to what you need for your outer material. It's as close to metalic gold as I can get on a transparent mat. This render is done with the default lights. Also turn flatten off and turn on shadows and best render. A good starting point for a metalic gold color is - Red = 150, Green = 80, Blue = 15.

Refraction is a whole other story. It is not possible with transparency in ZBrush. There are tut's on the subject but I can't recall any names right now.

[slocik]

there is refraction in zbrush
http://www.zbrushcentral.com/zbc/showthread.php?t=032481
it was metioned here, i eaven posted a screen of it :]

[Blaine91555]

:o I was not very clear - sorry. Yes, refraction is possible but not with this type of material. Also I can only get it to refract what is on the same layer. In this example you can see that when you place a translucent object inside of a transparent one it disappears. I don't know any way around this. Since transparency is only possible with the transparent item on another layer I don't think they can be used together. If there is a way it would be great. Does anyone know if that can be done??????????????:qu:

refract-test.jpg

[slocik]

tred to marge the leyers, and then use refract ?

[Blaine91555]

:o :o :o Now I really feel dumb. It is possible.


Create the background in the first layer. In this case I filled the layer with the photo as a texture and used the flat material.
Create the object with refraction on the same layer. Set the rgb level to below 100. Go to Draw and select Refraction and select the amount. Mark the position.
Create a new layer.
Create the object on the new layer by clicking on the marker so it is created in the same location. Go to deformation and change the size there if you wish. Apply the transparent material with the quality’s you want. Render with flatten off and shadows and best selected.

This looks great Blaine! Have to try that out...

[SpaceMan]

wow!!!! Blaine (http://www.zbrushcentral.com/zbc/member.php?u=40721)(BATMAN)91555 cool gold mat and refraction image:tu:

I used your new gold trans mat over a translucent mat

[Blaine91555]

Update and a warning. This only works while the object on the second layer is still in edit mode. When I exited edit mode the object in the first layer became opaque.

[marcus_civis]

There are som great effects here! :)



1 When I tried moving the top layer marker tool the marker tool on the other layer did not move with the top layer marker tool - how do I combine the two into one ztool to place in a comp on the canvas?

You can't do this with objects on different layers. If you use Multimarkers (or Marker Master) to group objects together they can only be drawn on one layer at a time. If you want to move two objects on two layers you need to repeat the draw/marking method for each layer.



2 Does the transparent mat top layer have to be on the top layer or can this be changed to put the transparent mat on the first layer render and then on the second layer maker tool use a different mat.and scale so that the transparent marker tool becomes a glow for the top layer marker tool?

There isn't a 'top layer' or 'bottom layer' in ZBrush. All the layers occupy the same 3D space and the numbering is simply to help you keep track of which layer you are working on. What matters is where in 3D space you draw your objects. For transparency to work the transparent object must be in front of the objects you wish to see through it (as well as on a separate layer). You can move all the objects on a layer forward or backward by adjusting the Displace Z slider in the Layer palette.

Sometimes switching layers can cause a loss of transparency. Switch back to the layer with the transparent object, do a best render and all should be well.
For translucency and refraction effects the objects need to be on the same layer. Sometimes baking the layer after achieving the effect you're after can be useful before applying a transparent object on a different layer.

[Blaine91555]

Thanks Marcus - I had not thought of baking the first layer.

[smileman]

Arggg, finally, I've done the refraction with Z, I'm happy now... I've still problems to import displacement map in Carrara, but I try many things in Z, and I will post new shaders ... thank you for the hands and for these material, very instructive...

wait and see

[SpaceMan]

Thanks Marcus:tu:

the scaling of the trans is not to easy to do - here's an image trying to scale it right - the jpeg lost a lot of the shiney look when I save it to fit on the forum
1paper1.jpg

[marcus_civis]

SpaceMan,
That looks good! The scaling will always be a problem if you are trying to fit two identical objects inside each other as the relative proportions remain the same. ;)

smileman,
There is a displacement in Carrara tutorial (http://www.eovia3d.net/showthread.php?t=5626) at eovia3d.net which you may find useful. (You may need to register at eovia3d to view it).

Cheers,

[SpaceMan]

Thanks Marcus I am starting to get into the work flow:)


I think we could use a scale micro incerment - + button for fine detailing:lol:

[marcus_civis]

I think we could use a scale micro incerment - + button for fine detailing:lol:

You can scale a model numerically by input to the Transform>Info sliders. These sliders change their propeties depending on which Transform mode you are in. So, with the Gyro showing and the Scale button pressed, values can be entered to adjust scale; with Rotate button pressed rotation can be adjusted; and Move button, the model moved. Adjust precisely by clicking on a slider and then input a value from the keyboard. Press TAB to move to the next slider down. Obviously for scale you will generally want to enter the same value for all three sliders.

HTH,

[Blaine91555]

I just had the same problem trying your idea to see what it would look like. Hope you get it to work OK. Looks like a great idea.

[SpaceMan]

Thanks Blaine91555 :)


And there are some really nice mats posted in this challenge :tu:

[SpaceMan]

LOL Marcus forgot to thank you for the scaling work flow:eek:

Marcus thanks for the scaling work flow post:tu:

[Blaine91555]

Erklanerbar - I'll have to post some more mats here as I get time. I know I've learned from others mats and appreciate them.

SpaceMan -

I don’t know if you’re still following this thread and I thought I’d post this while I was thinking about it.

I got interested in what you were trying to do. After thinking about it I realized that inflate is what is needed, not size. This seems to work out pretty good.

Place your interior object first as it is the smallest. Select the mat or texture and do a best render. Bake the layer and mark the location.

Create a new layer for the transparent outer object.

Click on the marker to place and select your transparent mat and go to edit modetest-1a.jpg . Then inflate a little at a time. This one was inflated about 10%.

If you try and place the outer larger object and then deflate the interior object you get unwanted results.

[Erklaerbar]

hey there, glad to see some life back in here. It is meant as an inspiring thread for everyone to post, and im sure there are quite a few people that like all of the contributions inhere. Dont get confused because it got a one star rating, someone is putting that on every thread i open ;) so nothing at all to do with the thread. I would post some more mats too if i had some cool ones. But then .... lets see. :rolleyes:

[SpaceMan]

Blaine91555 :cool: thanks for posting about using the inflate in the work flow. Your image shows that it gives very clean edges and fits the model so that it looks like part of the model and not two models put together:tu:

[Blaine91555]

Sometimes I don't know why such simple things seem to elude me and cost me the most time. I love working with materials and I'm always amazed at the possibilities. I took a break for a couple of weeks as my poor brain was getting clouded with too many things at once. I jumped into this to fast. Trying to learn basic modeling an ZBrush all at once was to much and I need to slow down and take it more methodicaly. Threads like this are really helpful and appreciated:tu: :tu: :tu: :tu: :tu:
