I'm trying to composite a shockwave effect with the blender render engine.
My scene is currently set up with two render layers:
Layer one: Text, two lamps and a camera.
Layer two: shockwave.
I have two issues currently, however I think the first issue may be beyond the scope of this question, I'm not entirely sure if it's something to do with the layer comp.
Issue One: The shockwave colouring seems not to be working from certain frames. Even though nothing is keyframed, everything seems to desaturate from frame 40 to about frame 100.
Issue Two: The final render is rendering the shockwave layer in front of the text when the object is behind the text. If I switch the alpha mix over node's inputs none of the actual shockwave renders, only the text layer.
