Filter Forge - Hard Shadows

Active Topics Search

jitspoe Posts: 187 Filters: 27	I was kind of disappointed that the ambient occlusion shadows did not include directional shadows, but the FF team made up for that by including scripting, so I took a shot at making hard directional shadows. Who's up for some rock hard shadows? Or would it be hard rock shadows (dunanananaaaa!). This is the default stones component. I mixed my directional lighting with the Filter Forge lighting so we could have ambient light and AO for more realistic appearances. Still a work in progress, but I should have a snippet ready for Monday.

Sphinx. Filter Optimizer Posts: 1344 Filters: 38	Cool, I'm looking forward to playing with it. About the sample count - you can stick in a blur (very small radius) btwn the heightmap source and your shadowtracer to get some sort of cache like functionality. That should reduce the real sample calculation greatly. Njyldgarkn sample cache!
