Hello Guys, need your help!
I'm doing scene with clouds, simple shader to volume, standart parameters to octane.

But i start render and little confused, becouse have two different results.
If i start octane IPR, shader doesn't work correctly,

after click update in IPR window, result looking more realistic.

Render to Mplay has a simillar error, shader doesn't work.

Have any rules or ideas for this situation? :roll:

Can you send to me the scene to test it here? The problem can be related to the bug (already fixed for the next build) in the IPR window updating the render target camera parameters, but this doesn't explain the problem while rendering to the MPlay.

Thanks,

The problem seems related to set the material for the volume using the Material SOP node. If you set the volume material in the OBJ material parameter, all seems to work fine.

I am investigating why this happens.

Thanks,

Nope, there is a bug in the plugin. Currently you can't use the Material SOP node to set the volume materials, only the OBJ material parameter can be used.

I'll try to fix it for the next build.

Thanks for reporting!
