Stuntmunky90 Posted April 3, 2006 Posted April 3, 2006 HOW DO U MAKE THOSE SUN RAYS UNDER WATER? anyone know? Quote
trajcedrv Posted April 3, 2006 Posted April 3, 2006 1. Add decal to the surface which has black-white (transparent) water- like pattern 2. Make klieg light above the surface, turn shadows to raytrace (you may add noise to the light) 3. Turn volumetric on for that light 4. VOILA: sunrays under water! Quote
Eric2575 Posted April 3, 2006 Posted April 3, 2006 Can you post an example of the decal please? When will Charles update the water tutorial? Two years ago he indicated it was in the works Quote
trajcedrv Posted April 3, 2006 Posted April 3, 2006 [attachmentid=15709] To make things more complicated: I have (with sucess) used two planes that had decals similar to the above one (sorry about low quality, but I think that you can get the picture ;-P), set to transparency and at the angle of 90 degrees at each other, and then made them slowly move in front of the light (at the angle of 90 degrees: one at the x, other at z axis)... volumetrics that result have very water - like qualitu... Hope that this makes sense! Quote
Eric2575 Posted April 3, 2006 Posted April 3, 2006 So this would be a targa image? Is the white saved as the Alpha Channel? Quote
trajcedrv Posted April 3, 2006 Posted April 3, 2006 I don't have actual files with me (I am at work, so that was the reason I put this example, made with MS paint) I was using Gray decal painted with airbrush tool and it was used as transparency decal... I'll see if I can post an example, but I think that you could manage on your own Drvarceto Quote
