Thanks for the quick reply beanzvision :)
Maybe I should Explain what I am trying to achieve.
I would like to created Inside volumes like the attached image A, plus add displacement on it( for extra detail or shape deformation) without having to create a very dense mesh and then using the standard displacement modifier from C4D, that could get heavy, if you have for example some textures controlling the Volume absorption plus C4D displacement modifier, i guess you can subdivide a mesh until it looks good, but again, sound heavy, I wonder if there is any other way ?
I also noticed that, lets say, you have a texture in the volume shaders Absorption slot, the shader set to Volume mapping on Surface, the texture mapping looks correct, but as soon as I change it to Inside volume it is gone, I usually have to use a C4D Projector, but it also does not work as in "on Surface" mode. Do you know a way around this ? I could be doing something totally wrong.
Thanks again for the quick reply. :)
