Stacking Materials

[pBarrelas]

Ok so this is an Octane limitation and not a plugin one. Is this something that's being addressed in the standalone and to be expected in the near future?

[aoktar]

yes, octane has not support as i described. I'm trying to add some features in plugin. But some fundemantal things are dependent to Octane's capacity.

Hi all,

Is there a way to stack materials with different projection methods ?
This is the last problem I have to switch my render from AR to Octane.
For one of my customers, I work often with a character which has bump stuffs on the body and
a logo around the chest. This logo should be fixed in spite of the deformations of the rigg.
In AR, I use camera projection for the logo, to resolve this problem.

Thanks !

you do it by using projection texture in imagetextures. change it to perspective mode, drop a camera do linkbox. Finally tweak transform of image

Ok Aoktar,

But it's what I do ...
However, I just noticed that the mapping projection did not seem stable in animation.
This is a bug or I 'm using it wrong ..?
You can find a test file in attachment (problem_camera_proj.zip).
Start playback to see what I mean.

Thank you very much.

ok, will check it. But try without camera linked. No need on your scenario. Object coordinates will help to you. Check your revised files.

This is a good solution Aoktar,
However, this is not usuable for my scenario :
The texture should be projected on a rigged character.
This character is animated, but the texture projected by "texture projection XYZ to UVW method" doesn't follow the mesh.

Example in attached file.

Thank you.

"Personally i prefer to wait a little about new improvements of Octane engine."

That sounds reasonable. Do you have any idea whether some of these stacking and tiling issues might get better in Octane 3.0?

Well, you actually can stack materials, when using polygon selection in the texture tag... this doesn't solve every mapping problem, but helps once in a while...
