I’m not coming over very often, it looks like the forums have changed so I hope you don’t mind me posting this up again.
Back in January I started a blog about materials. I’m still updating it on a regular basis, even it’s it’s not as often as I wish I did.
I’m still working with the udk, (although I’m planning on getting UE4 real soon) but everything is transferable. The nodes just look less fancy on my screenshots
I hope you’ll find it useful.
