I know it looks bad on the white background, but actually that’s alpha. These renders are meant to be decals over another pic.
Especially the translucency on the Ruby one.
Feel free to use any of these or the blend itself for your own projects.
Any advice on making the materials more realistic would be much appreciated.
Basically I want them to look like real gems.
In the Blend, one model has all three materials.
Just select which one you want in the material panel.
(I have them set permanent so they’ll stay with the blend whether or not they’re attached to a mesh.)
Feedback and critique is most welcome.
(Be as harsh as you like.)
Also an unrelated (and rather dumb) question:
How to set the Render resolution within Blender?
