Problems With Jason Welsh's Tutorial on VTC

ZBrush Usage Questions
#1

Hi all,

I am trying to follow Jason Welsh’s “Adding Texture to ZBrush” tutorial on VTC (part of Pixologic ZBrush v3.1 course), and am striking out with some texturing problems. I suspect that some of these problems below could be attributed to the fact that I am running ZB3.5R3, and the tutorial is written for v3.1.

To the best of my knowledge, all my settings are the same in my scene as compared to the tutorial. In other words, Standard brush, DragRect stroke, new “rock” alpha, in Edit/Draw mode, RGB Intensity=100, Z Intensity=70.

Differences are (i) I am now simply playing with the Sphere3D tool (2) There didn’t appear to be a “Fast Shader 5” material in ZB3.5R3, so I didn’t change the material from the default Red Wax.

Anyway here are the main differences in behavior between the lesson, and my session:

(1) When I import a texture, it doesn’t automatically apply (in the scene) to the tool that is on my canvas (it did in the tutorial).
(2) There is no Texture sub-menu under Tools, hence I can’t set Txr>Col, as specified in the tutorial.
(3) When I start up Projection Master, and select Colors, Fade and Drop Now, I get a dialog saying “Projecting Colors and/or Materials requires a mesh with pre-assigned texture or Polypaint mode active”. The button options at the bottom of this dialog are “Activate Texturing”, “Activate Polypainting” and “Cancel Projection”. This dialog does not come up in the tutorial. Furthermore, if I select either of the Activate options, the ability to change textures is disabled.

Any help appreciated.

you need to turn the sphere3d in to a polymesh3d before you can texture or polypaint it. right now it is a primitive.

#3

Select the imported texture from the Tool / Texture Map palette.

OK, I went to the Texture Map sub-palette to import the texture, and got a message that I had to turn UV on.

So, I went to the UV Map sub-palette and turned on UV Spherical. Then, I went back and was able to import the texture.

I then selected a different texture, and found that I was also able to drop into Projection Master without getting that warning message.

Problem now is, when I am in Projection Master, it paints the material and not the texture (I did NOT have the material option checked when entering PM).

My other concern is that this is starting to look less and less like Jason’s tutorial. Surely the changes from v3.1 to v3.5R3 have not been that drastic ???

Confusion reigns supreme.

#5

even you didn’t checked the Material in PM you need also to turn off the “M” in the upper part. and make sure everything is turn off except Rgb.

I’m not getting the answer(s) that I need…Let me reiterate this more succinctly.

In ZB3.5R3, how do you apply a texture to your model ?

I’ve searched high and low for the answer to this, such a simple thing you would think it was easy to find. Its absolutely aggravating the snot out of me.

#7

import the texture. either in the texture panel at the top, or on the left hand side if you have the standard UI.

then
tool>texture>big button – select the texture you want.

This happens on a per subtool basis so you can have multiple textures applied now…instead of the one it used to be.

#8

That is a problem in itself… in 3.5R3, there is no “Texture” sub-palette under the Tools palette.

#9

have you tried looking at Tool / Texture Map by any chance? Your model must have UVs.

Richard

#10

Thanks, Richard. That is getting very close now. I have been able to set a UV Map, and then apply a Texture Map. So, that is progress.

However, I am still stuck on the next step in Jason’s tutorial, which is - once the texture has been applied (via the Tool menu), he then goes into Projection Master, selects a second texture (in the Texture menu) and paints using the second texture while in Projection Master.

My problems are twofold at this point :

(1) I could set a second texture (via the Texture menu) and then go into Projection Master, but not the other way around. In other words, once I was in Projection Master, the Texture menu was disabled. That didn’t seem to be the case in Jason’s tutorial;

(2) If I set a second texture (via the Texture menu) and then go into Projection Master, it paints using the color but not the texture. Note that I could paint the second texture using Polypaint, however.

#11

maybe it much easier to see a screenshot of your problem.

#12

Here is the screenshot.

As you can see, I have set a UV map, and applied a texture map to the model. I then selected a texture from the left dock, and dropped into Projection Master. At this point the texture box becomes disabled, and I find that I can only texture with the current color.

So, my question is : how do texture while in Projection Master ?

As goast666 posted earlier: Tool/Texture map and select the texture you want to use by clicking on the (still) empty icon and selecting the texture you want to use.

#14

No that does not work, because the Texture Map sub-palette is no longer available once you go into Projection Master.

#15

if you switch to the simplebrush in tool palette you can use a texture from the texture menu (not the tool texture menu)

#16

spaceboy, that does not work either. True that it enables the texture palette, however when you choose the texture, it paints on to the canvas, not the model (I am talking about when you are in Projection Master mode).

I am trying to work out how to paint the secondary texture (i.e. from the Texture palette) on to the model while in Projection Master mode.

#17

um yes i was in projection master when i suggested that.
perhaps you should list the steps you are taking.
also might help if you can post a link to the tutorial, i think he had some of those vtc’s as samples.

#18

Here are my steps:

(1) Load up DemoHead;
(2) Put in Edit mode (if not already);
(3) Change material from Red Wax to Basic Material;
(4) Go to lowest sub-division level;
(4) Apply UV Map - Packed UV Tiles with Map Size of 2048;
(5) Bump sub-division levels back up;
(6) Click on Tool>Texture Map and select Texture 25;
(7) Click Texture On button (applies the texture at this point);
(8) Click Projection Master button;
(9) Accept defaults, i.e. only Colors and Fade checked and click “Drop Now” (note: at this point, it appears to drop out of Edit mode, as the Edit button is no longer highlighted);
(10) Select Simple Brush from Tool palette;
(11) Select Texture 21 from Texture palette;
(12) Start painting - at this point it paints on the canvas, not on the model.

I note that when you go into Projection Master, it defaults to the Single Layer brush. This continues to paint on the model. But as soon as you select the Simple brush, it paints on the canvas.

So, this seems to mean that you get access to the Texture menu at the expense of being able to paint on the model.

Andrew

PS Jason’s tutorial is here. Then, go to the “Adding Texture to ZBrush” movie.

heres a really quick video

jason uses the directional brush in his vid and i did here as well

#20

Ah, the directional brush. The missing link. Just goes to show that you have to be careful to observe every detail of a zBrush workflow.

I don’t know how many times I watched this tutorial, but missed the bit about the directional brush.

Thanks, spaceboy412.
