Title: overlapping trans maps glitch
Post by: karate5662 on June 09, 2008, 05:03:45 pm

When i render using the raytracer and overlapping trans maps, the trans maps seem to cancel eachother out:

Are your transparent shapes fully enclosed 3D objects or are they just single poly thick?  The ray traced transparent materials only work properly on fully enclosed 3D objects.  The ray tracer keeps track of whether it is inside or outside of the object - so it get's confused when there is no inside.

I'm assuming that you are using the new ray-traced materials dialectric or transparent.  If you use normal Anim8or materials for transparent objects that aren't full solids you should get the correct result.

The dust objects are just a single polly thick. I'm only using the default anim8or materials though, so i shouldn't be having this problem.
I'll try fully enclosing the objects anyway and see if the helps.

ok...
the problem went away but now they cast shadows on themselves in raytrace mode even when I don't select fo them to cast shadows.

Send me your .an8 file and I'll loonk into the problem.  If you can reproduce it wouthout the tank then it would be better to send that file.  I'll need the textures that you're using for the dust as well..

I can't seem to reproduce it any more.
I'll let you know if it happens again though.

head over to animanon.com and go to the "get tanked" contest board.
I have one that's 10 times better.
