Just for the fun, I've been trying to reproduce the avatar Jamis use on the forum:
I still far from it, it's quite difficult to play with the materials when it takes a couple of minute to render the scene (yeah that pesky dragon add a lot of work ) I've acheived an interesting result, but I've played with a lot of parameter, but am unable to get a transparency result like on his avatar.
Also counting that he is probably using a spot light; but it is hard to tell as the resolution is really low.
Jamis, if you are around, would you like to share the scene, or at lest how the material of the dragon is made?
I have to admit that playing with the material is (for a complexe scene at least) more painful than I originally thought. Maybe I should add an option to render just a small part of the scene at full resolution to see the changed of the material without spending minutes between each changes just to see the difference. Rendering the full scene at low resolution is useful for object placement for exemple, but light interraction or just material interaction is too low resolution to be really useful.
Hello godzil! Yeah, my avatar uses a spotlight, from (0,10,-10) to (0,0,0), with a width of 25 degrees and a fade width of 5 degrees. I'm afraid I no longer have the specific scene for it, but it's a glass texture, probably typical of what I've shared elsewhere on the forum (low ambient/diffuse, high specular). I wish I could be more helpful!
