mike Posted September 18, 2002 Share Posted September 18, 2002 That's exactly what i mentioned in my post before. 1. make i3d texture ( simple sphere ) 2. Place a normal light(fastshadow) with a projectormap (some black and white noise ) on top of the athmosphere object, wich includes the above 3d-texture and than render the scene.

danteA Posted September 19, 2002 Share Posted September 19, 2002 What about the volumetrics tutorial by Jason at http://odforce.net/tips/ ? Quote Link to comment Share on other sites More sharing options...

Ok here it is. I have not included textures for floor and background. Again the main importend thing is the "projectormap" and the light must LOOK through the i3d texture. vol.zip Quote Link to comment Share on other sites More sharing options...
Szymon Posted September 19, 2002 Author Share Posted September 19, 2002 Done before downloading your file Mike Thanks for explanation It was very helpful. Weird, but every time I want to make something in Houdini it's simpler that I think. I have to practice more to think Houdini I gues For those who can't sort out the problem, I'm also ataching the file. Don't forget to change the path in v_texfog1 shader, and light4 Projector Map. Mike, thank you again VolTest.ZIP Quote Link to comment Share on other sites More sharing options...

tuangD Posted September 26, 2002 Share Posted September 26, 2002 Hi again, I think I can make a simple volumn light now. I've attached an image here. And I have another question. Look at the picture when light pass those colored glasses. (normal vex texture with diff and transmit value set to be the same) fog has the same color still, may be because of the Fog color setting. So I just want to know. Is there any way to also change the color of those fog to sync. with those colored glasses? thanks all in advance Quote Link to comment Share on other sites More sharing options...
mike Posted September 27, 2002 Share Posted September 27, 2002 sorry no special idea at the moment, but I will try something.... Quote Link to comment Share on other sites More sharing options...
mike Posted September 27, 2002 Share Posted September 27, 2002 OK, one possible way, use a second light with a projectormap which looks like your colored glas, set this light to orthographic an place it exactly at the "glasobject". It is only a fake, but it works Quote Link to comment Share on other sites More sharing options...

sirogi Posted November 17, 2002 Share Posted November 17, 2002 just to revive this thread... it's simple enough to have nice light beams running through i3d volume clouds...but what if you want volume shadows? (like the poster oroginally intended) create one atmos. object for the light rays and another for the actual clouds....the first one to figure out how to cast decent volume shadows from the cloud inside the atmosphere gets an ice-cream....(or a beer ) cheers....
