shadow terminator

Post by lacilaci » Thu May 30, 2019 10:40 am

how high or low on the "todo" list is treatment of the shadow terminator?
I'm gonna need some sharp lighting on cad models and I'm scared :lol:

Subdivision surface wouldn't help?

it's a cad tesselated model, you can't subdivide those, also subdivision doesn't help much with stronger bump mapping.
On top of all that I will probably have to use some sharper lighting at some point and that will definitely look much worse.

This needs to be fixed/treated... The question is when.

I also wonder if it is possible to make the bump mapping so that stronger values don't break overal lighting. Cause sometimes I tweak bump mapping close up and everything looks nice, then I back off with camera and it's a shit show of weird lighting

I see...

The Disney BRDF uses a different glossy model, maybe it will help.
