VRayColor2Bump / Vray Adv 2.20.03 and object scale

[stilgarna]

VRayColor2Bump work as a normal converter for B&W maps, correct me if I'm wrong.

It work great, better than directly using B&W map into bump... It's close to awesomeness !!! very close !!!
BUT, I get a terrible issue, when doing very high resolution, bump disappear.


I've got this issue with max bitmap and vrayHDRI.

When up-scaling the object from 1 to 10, problem disappear, maybe there is a clamp or something in the VRayColor2Bump.
Is there any chance to see a fix quickly, because I'm currently working with this feature and I can achieve the same render without it.

We recently made heavy use of VRayColor2Bump and can't go back quickly.

I can't work with up-scaled objects because I working for industrial purpose and It's too hard to work with wrong scale. Based objects are 3.5 cm high.


Here are some examples : (Very noisy because of a very low setup)

4000px x 4000px :


4500px x 4500px : less bump in the center


5500px x 5500px : even worth


Hope you can fix it !!! best regards.
