RT GPU - Bump map not working for me

[MildMustard]

Hi, is there something I need to add or be aware of. Bump doesn't seem to be working for me in RT GPU.

Using nightly 21/09/2015 (26246)

Bump mapping works only with bitmaps in the current version (procedurals are not supported yet).

[BVA]

I also cant get bump maps to work with bitmaps?

Just like BVA, I cannot get bump with bitmaps in RT-GPU. (RT-CPU is working) I am not using procedurals.

Okay, my bad. I haven't test in Modo, to be fair.
I guess it is something related with V-Ray Modo in that case. Will check that will Vlado Nedev.

This is fixed for tomorrow's nightly build (the one from 2015-09-26).
The problem was that I was using a "procedural" texture to convert the color of the bitmap to a scalar value for the bump, which like Blago said is not supported in RT GPU for bump maps.
Be careful not to change the default values for the "Low/High value" channels of the image map, when it is used for Bump mapping in RT GPU mode,
as this remapping is done using procedural textures too and the bump will disappear entirely.
