The material that I’m using appears very small on the object. Is there any way to scale it without having to adjust the original image?
Re: Material Scaling
I have the same problem 
please some one help us…?
Re: Material Scaling
You need to re-size the texture image in sketchup, in the material editor. Simply choose a different size for the image.
Re: Material Scaling
but then u gotta make sure ur materials are linked materials.. coz only then the changes that happen in SU will be correspondingly made in the Vray materials as well! 
Re: Material Scaling
I would always start with the materials applied in sketchup
1 - you can immediately see what you are getting
2 - you can scale and rotate the texture etc
3 - it provides the UV info for vray
only if you want to apply further layers (bump, reflection), is it necessary to either link the material or apply a vray material (I do this for glass)

Re: Material Scaling
The recommended workflow is through a SU linked material. The main issue is because SU does not create UV information for a object unless you have a SU material with a texture applied. Without that UV information it will be very hard to get things adjusted right.
Re: Material Scaling
I am new with dese kind of programs and i do not know hou to use the SU linkt material.
I am using when I download a Texture form this site than I need to set the UVW at U 0.002 & V 0.002 to see a correct texture in my renders.
What am I doing wrong…??
Re: Material Scaling
1 - download the vray material
2 - in sketchup, ‘import’ the material and apply to the model
3 - this is then a regular sketchup material and can be re-sized, rotated, re-positioned etc. in sketchup
4 - if you want bump etc. then follow the tutorial for creating a vray linked material. so that you can apply the bump map that came withthe downloaded material.
Good luck

Re: Material Scaling
thank you for your help.
I have one more quetion if I re-size my texture in sketchup (downloadid from this site) end I want to add the bump-map do I need to resie that than in the UVW map…?
thanks for your help
Re: Material Scaling
I am pretty sure that the bump map will be scaled the same as the texture (it will get its uv info from the same place) so you don’t have to adjust anything.
