So you can see when I go to render, the colour of the materials revert back to the orginal colour. I changed the colour of the materials in sketchup to achieve what I wanted.
VfSU doesn't support textures modified by SU. You must edit the texture in a image editor.
ps. it helps if you post your VfSU version number when asking questions. Some versions behave differently from each other.
