How to scale materials?

Hi!

I’m new to v-ray and i was wondering how i scale materials, they seem to be about 1000 times larger than they should be.

Thank you for answering,

UVW MAP - I use MAX, but I think it is the same.

You have to set the mapping scale in Rhino’s object properties.
Add a texture mapping to your object, such as planar or cube, and set the mapping size as you want your texture to appear. A good reference: Texture mapping in Rhino 5 for Windows
