sanostol Posted March 22, 2010 Share Posted March 22, 2010 Hi I'm working on some volumetric lights in houdini right now. The lights are instanced and I need volumetrics with shadows. the litfog atmosphere shader works, but with many lights it gets very slow. so I turned to the fastzmap, as I understood it in that way, that it uses the existing shadowmap to create the volumeeffect. but unfortunately it does not look good right now. the cone has no falloff at the borders and it does not use the light fallof. another thing is that it uses aperture and focal instead of the coneangle of the light, what makes it tricky to adjust.Mixing volumes seems not to work well, too. Does anybody know how to use it to get something like this: best regards Martin Quote Link to comment Share on other sites More sharing options...
