Afterburn shadows not showing when rendering to texture - Robert Sundin - 07-04-2006
Hi!
I´m trying to make a baked texture that includes the shadows cast by Afterburn particles. But the shadows won´t show up in the baked texture. Shadows cast by other objects in the scene show up correctly in the baked texture though. Is this a limitation in the render to texture function? Maybe the shadows won´t show up since Afterburn is an "atmospheric", and not an actual object with geometry?
If anyone has any ideas on how to solve this, please let me know.
Regards
Robert
PS I´m using Max 8 + AB 3.2

It's probably because AfterBurn is an atmos. effect.
I'm not sure how you could do that.

Thanks for the answer Kresimir!
I´ll try to find some other way around it.
What I'm trying to achieve is to get a picture of a "slice" of an Afterburn puff that changes over time. The idea was that the dark shadow would outline the puffs shape on several white planes that intersects the AB puff at different positions. I would then render to texture those planes and then use the textures as opacity maps on the planes. Sort of a "fake" Afterburn effect. Does this make any sense?
Maybe it´s possible to achive this in some other way.
Thanks for your help
Regards

You can try to fake AB without AB.
Basically, you can put slightly Noise textures to different planes and render.
If your planes are static, you can use world texture coordinates, so that texture changes over the space... if not, use object's coordinates and play with X,Y,Z offset.

Thank you,
Yes I know about that technique, but it doesn't look nearly as good as the the AB puffs in my opinion.
But maybe I can do it that way anyway.
Thanx alot
