Several years ago I made a series of training videos to teach artists how to write real-time shaders in HLSL. The series starts out with very simple concepts so that someone with no programming experience at all can start right from the beginning and learn to write shaders. Further into the...

Sounds like you're making some progress - although 20 passes is insane. Are you joking? I got similar results with 2 passes, and really nice looking results with 4 - but that's probably too many for real-time. Can you put the file somewhere else? I tried grabbing it at that link and just...

I don't have a head that I can give you, but I can probably fix the UVs on the one that you have pretty easily. Let me know where you found it and I'll see what I can do. My experience with the Poisson Disc filter is that it doesn't look that great if you run it just once, but if you run it...

I'm also working on this problem. I'm currently implementing this type of real-time sub-surface scattering as a new node in ShaderFX. I also tried the method that you have posted and ran into problems - not quite like the ones in your screen shot - those are really weird looking - but I wasn't...

I think that artist talent is the most important factor. I completely disagree with deathkiller on that point and I actually question whether it's realism that we're after. If I want realism, I can just take my camcorder out into my back yard and shoot some footage. That's about as real as...

Actually, the fact that people are complaining about the plasticy look is a good sign to me. It means that real-time graphics are getting to the point were we can actually achieve the look of a real surface. Since it's so new, we haven't done a good job of anything but plasticy yet - but it...

Thanks a lot for your quick reply. Using world Z as the up direction isn't a good solution because the closer my light vector is to the world Z, the less correct my results will be. However, this should work for now - as long as I keep my light source on the same horizontal plane as my object...

I'm trying to write an HLSL FX shader that will run in 3ds Max that will allow a model to cast projected shadows on itself. I've got the whole thing written, but I'm having some issues with the light transform matrix. Max doesn't allow me to pull in a pre-computed transform matrix for the...
