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.  |

Doesn't it do directional shadows if you use a point light?

Math for the normals wasn't quite correct in the previous image. I think I've fixed that, and I cranked up the ambient light and down the environment light to make it look a little more natural. Here it is on cells with a circular arc profile.  |

uberzev: I had hoped that, but as far as I know, the FF lighting system does not support directional shadows.
Here's the default stone again with more correct lighting:  |

Cast Shadows! Very cool - do you trace them or is it some smart displacement trick? |

They're traced. It's a little bit slow (requires about 200-300 heightmap lookups per sample), but I think it's worth it. I submitted the filter this weekend, so it should be available shortly.

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. |
