bad buckets on certain materials

V-Ray V-Ray for 3ds Max Issues
1

Hi

This is a problem that I have been dealing with since SP3 and never got an answer:

please look at the image:

I use a simple VRay material for the windows elements and get some buckets rendering with different tones - Note that there is no map used in this material - just plain material.
reflection is set to about 10 but other than thta - nothing
I had thgis problem even with WARD and Phong in the BRDF.

As you can see the other area were rendered OK.

BTW - I only noticed this in a Birdseye view render and not in the view taken form a human eye level…

It should work if you disable the interpolation option. This issue is fixed in SP4.

thx but where exactly is this parameter ?
Is it in the material GUI or Vray’s GUI ?

EDIT: This was done in SP4

It is right below the reflection subdivs parameter in VRayMtl (it’s labeled “Use interpolation”).

So should I use it in all of my materials ?
I ask because I always use interpolation (as it quickens rendering)

ALso - Are u saying that in SP4 the interpolation can be used as before ?

This particular problem is fixed in SP4, yes. However it might be better to wait a little until we release SP4a before upgrading.

now that SP4a is released - was it solved ?
I am hesitating to install SP4a.
