VRay material swatches UV tiling

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

How do I change the UV tiling in VRay’s material preview swatches?

Could you clarify your issue a bit?

How do I change the scale of UV mapping on those spheres:

are those preview scenes accessible somewhere? as a .vrscene maybe?

with triplanar mapping especially it is hard to read the preview.

Yes, it’s located here: C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax2024\assets

is
VRay_Preview_Bake_Scale=1
what I should be editing in the .vrscene file?

6

Yes, however, I’m unsure if it’s designed to be manipulated. Values below 1 don’t seem to do anything. I’ll ask around.

thank you, much appreciated.

Is there a reason not to use IPR? We ask this because, even if you adjust the preview scene to show the TriplanarTex that does not ensure the result will be adequate for the object-to-render. Also, if you adjust the UVs for one shader, that would not necessarily work for other shaders (no perfect value). Not many people ask for this, so it’s better to discuss the pros and cons of having such adjustability.

To be honest a per-meterial preview uv-tiling adjustment wouln’t be unwelcome…

sure, modifying the preview .vrscene would be partial solution. IPR is fast but mat preview is faster. VRay introduced quite a quality upgrade for the swatch a while ago but it is missing some functionalities of native 3ds max one (scale - although quite limited and preview options for cylinder and box).

UV tile scale adjustment per preview ranging from 0.01 to 100 would obviously be perfect.

IPR sure, if it would be stable or didn’t update if I farted, but it’s not.
