Realistic Textures for VEX CAD

Does anybody know any good textures to use for VEX CAD on Autodesk inventor?

For some parts, I have had to download the STEP files from the VEX Website, but I can’t find any realistic-looking appearance textures for them. Some help would be appreciated.

I’m mainly looking for textures for the High Strength Drive Shafts

Those aren’t textures, you’ll need to apply materials to those bodies. I did this in my Build a Bot series.

Just Google Inventor Appearances. Don’t get confused by the difference between physical and regular appearances.
