32bit Displacement Clipping

[ktysdal]

I've been doing quite a lot of experimentation with 32-bit displacement and it looks like the negative colors gets clipped



there is a checkbox called "Allow negative colors", under Texture/Bitmap, that sounds like it should fix this but it doesn't seem to work.

heres the test file:

Hope this is a clear and easy to understand, if not then i can try to explain clearer.

thanks

Yes, it seems to be a bug. I confirm that negative colors exist in this texture and vray is not able to read these values.

Re: 32bit Displacement Clipping

Under "Influence" panel set "Blend" to "None" - this will fix the issue.
This is because all textures are blended by default to their correspondent colors, but accidentally this as also done to displacement texture, I'll fix it a little later and by now use the workaround.

That's nice. Thanks for looking into it
