Bump map & reflection

V-Ray V-Ray for Revit Issues

Hello all,

It’s me … again :slight_smile:
I’ve tried to make materiel with ‘vein’ but I’got a strang things, artefact and not usual reflection.
I use a gradient map to make my bump and it seems that ‘veins’ make reflection (I can see roof elements that I must not see normally).
So I put my gradient map in the reflection slot to see if it works like a mask : didn’t work, I invert this map : not much better.
If I remove my bump map, it works fine.

Any idea ?
I join the VRMAT and picture.

Hi again Mick,

Can you also attach a picture showing the effect that you want to achieve?

Best,
A.

Why not add reveals to the wall?

It is not necessary, Kraig, since the effect can be achieved in the material itself.
