So I want to try to model Crackle glass for a personnel challenge, but really have no idea where to start. Any ideas? I thought about bump mapping but I don’t think it would look much like this…
in cycle
there is a script to make cracks for 2.6 also
see wiki page
If you wanted to get really hardcore you could use the fracture tool (in the add-ons) to make physically accurate cracks. Just make sure you don’t use smooth shading to render the result; the edges will look funky.
A more economic alternative would be to map a glossy texture to a voronoi pattern. I think I’ll go and try that right now.
I just tried the fracture tool, not exactly accurate but close.
Thanks for that tutorial Ricky, ill watch it and see if I can use anything from it.
(edit)
Without smooth shading, better but still not there
(edit again)
Tried bump mapping in cycles, looks pretty bad.
IDK, the top fracture image looks pretty good, and with a little tweaking could probably give yo want you needed.
Yeah this time I used two particle systems for small cracks and larger ones and duplicated the amount of vertices on the mesh.
Results are pretty good
