stained glass, volumetric
Can anyone describe a quick way to get the colors of an image mapped stained glass window to show up in the light beams using LightFog?

not 100% sure but you may need to use a barn doors style technique or a cookie cutter and place the image in the colour component of the lights's attributes. try that, I would try it out for you but my machine is rendering so I cant stop it right now.
I may try later if I get a chance. Alan |
Also might be a good idea to look at doing it in post.
A good VFX rule-of-thumb, is that unless you need to fly through it, or something TRUELY volumetric, you can do it in post with a LOT more controll, and WAY faster:) After Effects 5.5 pro bundle, for example, has a "volume-light" type of 3d light effect, that does EXACTLY this effect you want:) -Simply put a few locators in your Maya scene to help you line up the "beam". -then save that file out as a .ma file (just the locators and camera, no geometry) (you can even ANIMATE the camera!) -then import that into after effects -place an After Effects light in the scene using your locators as exact guides. -add the stained-glass image to the light color -turn on fog -tweak light position, and parent it to one of the locators. -and you're done! FIRST though, you might wanna try what Pure was saying about the lights' color channel. It might work perfect for you. With Maya, you never know:) hehe... Good luck! |
