V ray texture

After i apply a texture from v ray editor i can not change the texture size in sketchup. Does aynone know why?

What texture exactly (name)?

For example the iron blurry 5cm, and every texture with a size in v ray that i apply i can`t change the size in sketchup.

If it does not have a texture in the Diffuse slot, use Binding > Custom Mode/Texture Helper for resizing
