Second level of Bump Multiplier wont work with GPU

V-Ray V-Ray for Rhino Issues

Hi Guy
When I try to use a second or even a third level of bump, the multiplier (Amount) wont work. This is very critical for us, since we changed to GPU rendering and spent a lot of money on hardware.
Here is quick video explaining my issue.

Please, can you add support for this on the next build?

Thank!

Hi @javierrentas ,

Thank you for the pointer - we’ve reported this under VRW-3387 and we will let you know when we get any updates from our developers.

In the meantime, you can use Blend Material as a workaround to achieve multiple layers of bump, which you can control via the blend amount slider.
