VRay 3.5 bump problem

[Jiri.Matys]

Hi,

I made very simple scene just to test something, but I found this bug. I thought bump in VRay 3.5 will be without any problem. But the sharp edge is terrible, cant use that. Can somebody correct it or where is a problem?

Sending scene in zip file.

Thank you

Hello, anybody? Or is this normal result?

We have not made any changes to the actual bump mapping yet. I did show some experiments, but they need more careful research before going into production. I'm planning to look into that more seriously for 3.6

Best regards,

Would using a vrayhdri map and setting it to elliptical filtering help?

No, it's not a filtering issue and has nothing to do with the particular texture used for bump.

I've been able to reproduce this in 3.40.01. Either having the bump set high, like 100 for example, or turning the blur down to 0.01 gets similar results to this.

I set bump for 30 or so and didnt change filtering if I remember correctly.

I hope to get to it.

I ran into a similar issue in Maya. There the issue was actually with the subdivision surface that is built into Maya (when used in combination with a high frequency bump map). Adding a Vray subdivision surface attribute to the geometry fixed it. You might give that a try here.

Its still a problem in latest nightly

Does the solution for this problem come with V-Ray Next?

It is a comparison with arnold.
It seems that arnold is taking measures

This problem has been debated from long long time ago. Why is V-Ray still not solving the problem now?
