Iām trying to the tutrial on Maya5.
but I canāt find Where is
1)ārender as subdivision surfaceā in shape node.
2)āilrDisplaceā
3)Displacement options
āFlip textureā
āDisplacement offsetā
āDisplacement scaleā
Iām using Lambert as shader.
Generate the displacement map correctly.
How was the Head TestModel Displacement Map Createdā¦?
Adaptive or DPSubPix 4ā¦?
The Reason I ask
When i import my models into Maya they are kinda small (compared to the Head Test)
How to get Models created in ZBrush Exported out at a larger size , for use in Mayaā¦?
If i change the Init ZBrush>import/export scale > Unify Scale to 12
Will I also need to change Tool>import/export>Scale to 12ā¦? (default 1) http://www.pixolator.com/zbc-bin/ultimatebb.cgi?ubb=get_topic&f=4&t=001662
The TOOL Export settings i have set scale to 12, and my ZB model did import into Maya much lager, but will that generate the wrong scale for the Dispplacement Map?
Every Thing i import into Maya from ZB2 seems Bloated. I think i may not have high enough Geometry to get proper Displacement.
I will post some pictures of āBloatyā my Fish test modelā¦Itās kinda funny looking, but this ZB to Maya Displacement thing is geting very frustrating.
Thanks!
Bloaty the Mental Ray Rendered Fish thing

Hey, I was wondering if any one can help me.
Iāve been trying to get the displacement to render properly in both mental ray and vray in max6. Iāve been reading through the posts of both threads and experimenting with values (mainly for vray) suggested in said threads.
this is pretty much what always happens
so seeing as this spacing occurs in both mental ray and vray im going to assume its not something to do with either of them but something im not doing else where. I downloaded some .obj importer for max 6 from somewhere and this imports both the head and the sword in extremely small sizesā¦what importer do the rest of the max users use?
any help would be appreciated.

To Kael: One thing to try is adding a mesh smooth modifier to the model (which I always convert to editable poly). The export/import settings Iāve found to be highly succesful can be found here. For the Vray displacement modifier values, you should use a negative shift value half of the dispalcement value. So if for example you use a displacement value of 14, you would enter -7 for the shift. This is because the map from ZB uses a 50% grey as no displacement. If you donāt want to use shift (can be buggy I hear, never had any trouble here though), then you could try setting the RGB offset for the map (which you should have loaded into the material editor for control over it and instanced to the modifier, right?) to -0.5, though it has also been suggested that setting the black point of the color map to -1 is actually better.
Thanks Zeddicus for your reply.
I finally got it working after i posted.
thanks again

Iām attempting this in 3dsmax 4.25 with the standard displace modifier with luminance center at 0.5 and strength=17 as suggested by julien. Iāve also converted the mesh into an editable poly and added 2 levels of further subdivision. I canāt seem to get the map to situate properly on the mesh. My only experience with displacement before this is to simulate terrain on a plane and it has worked fine. Do I need to switch the map from planar to spherical because the mesh is a head? Or is a matter of rotating or scaling the map?
tumbleweed: Have you flipped the map vertically? You can do this in Photoshop, or simply set the maps vertical tiling to -1.0 in the material editor. Could you post a picture of your render? That might help us a bit more in helping you.
Here is a cropped screenshot of the problem
Try checking the āUse Existing Mappingā option for the modifier.
Thankyou very much, that did the trick! Now itās just a matter of tweaking strength and luminance!
What am i doing wrong with XSI? I canāt even get the displacement to register, it just renders the subdivided object. Iāve tried the render tree setup like in the practical guide and the one posted here and it just doesnāt work. If i connect the image to the surface channel i can see the displacement map so i know itās being applied, itās just not actually doing anything. What am i missing?
Anyone with XSI maybe post their scene so I can look at the actual render tree setup? Still new to XSI and havenāt really gotten it figured out yet.
I thought iād post this incase anyone is as stupid as me and makes the same mistake and since i havenāt seen it articulated iād thought id just say it for the forum search engine.
if anyone has the same problem as i did (in max 6.0) with the polygons seeming to float apart and come adrift as in the pic above the answer lies in the meshsmoothā¦make sure in the surface parameters smooth result is on. If it is not i always get the drift problem.
most people seem to know this but there is always someone else with the same problem.

How do I know whether C4D is reading the displacement image as 8bit?
Thanks
Pixolator,
can you post your exact procedure for exporting those displacement maps, I cannot as of yet, followed the practical guide procedure 10 times, produce any readable displacments in cinema like what you did with the sword and head object.
I have no idea of what to do.
[moved to new topic]
Hi everyone!
Does anyone know if you can render displacement maps in max 5.0 or do you need to upgrade to 5.1 with the service pack or 6.0?
yes, I too would like it if pixolator could describe exactly the workflow in creating a displacement map. 
Zeddicus: You seem to be the one who have solved the problem of banding in mental ray. I followed your steps with no luck at all. Used your import settings and used your render settings and still bandingā¦
Could you post your max file? It would be interesting to have a look at itā¦
Hi Zeddicus
Iām also having a problem with your post in the main forum.
Mainly the part that reads ā¦
<BLOCKQUOTE>quote:</font><HR> - For render options - View: Checked / Edge Length: 1.0 (higher speeds thing up but lowers render quality, lower setting slows things down but improves render quality) / Max Displace: 15.0 / Max Level: 6 (play around for best speed to render quality ratio) <HR></BLOCKQUOTE>
Iām unsure where the Edge lenght is that you are refering too. Please help!
:b4: Edit :b4: Found it! Sorry that was starring me in the face! How embarrasing!
Hi there,
Trying to get this thing looking right - it still appears bloated to me. Using XSI 4.2 Foundation, and as you can see with the screenshot, Iāve tried using a change range node, or two scalar maths (two different methods from different posters) but I still feel itās puffing out (0 = no displacement, 1 = full displacement) Itās particularly apparent around the nose / lipsā¦ Cheers for any help! (Or tell me itās fine)
