well, i'm alive and kickin'
But i haven't had much time to work on shade-c in the last weeks as i have some personal stuff going on. I will most likely continue working on shade-c in june.
As for new effects:
Yes, i have some new things and some of them are already working quite good. But i won't release a new version until they work the way i want. I also wan't to change shade-c so it makes use of structs instead of skills as heelx suggested.
To name some of the new things i was working on in the last weeks/months:
dynamic gamma correction for the hdr shader (i'm this close to get it done finally)
Soft Stencil Shadows (PPE)
different kinds of toon shaders (PPE and object based)
advanced normalmapping shaders
team-fortress-2-like character shader
some shader "studies" which i might include as they turned out kinda nice

some screens:
scene without any shaders



First try at TF2 shader



PPE toon shader + tf2 shader



PPE toon shader



object based toon shading



Gooch shading + PPE toon shader



Some screens of my demo app (guess you have to see it in motion to actually notice the new stuff )










Well, thats it for the moment. Nothing really fancy, but i kinda like it
