All of the sudden I encountered a scaling problem.
After applying a vray material from the library to an object a scale is set.
Adding a uvw map on the the object I can adjust the scale as I need it in the viewport, but the rendered scale wont change.
No matter how much I adjust the uvw map, I always get the same render resutl although the viewport shows the changed scale.
What am I missing???
Tried reinstalling vray, didnt work.
No real world scale options checked.
Did I press a key shortcut by mistake or put a check somwhere in the render settings?
Using Vray 5.1.1 with 3ds max 2021
Maybe the texture’s map channel does not correspond to the UVW map channel applied to the object? Do attach some screencaps so we can take a look.
The Channel is the same but I think I found the issue due to your hint 
It had to have something to do with the mapping and I discovered that when importing vray material from the vray library the default mapping source is checked and a triplaner map loaded, blocking any adjustments in the uvw modifier.
I unchecked the box and the texture rendered as seen in the viewport.+
Is that new?
I didnt have this issure before.
Thanks for your help!!
Well, some materials from the library are just set up with a Triplanar node. To manipulate the mapping you may do so in whatever way you like.
Thanks for clearing this up
