Question by Kourosh · Oct 10, 2011 at 10:18 AM · shadertransparencyissue

Strange effects of two transparent objects on each other.

hello friends,

I have a waterfall over a transparent stone. When stone's transparency is 0 the waterfall appears, and when is 1 the waterfall is hardly seen. I'm so bewildered as where to look for the cause. I just guess that tweaking shaders might be helpful. (but don't know how).

Any suggestion on this matter?

It could be a numerous of things, but I'd first check that the shader use 'ZWrite On' on both objects. It sounds like the stone gets rendered on top of the waterfall.

Thank you save. Waterfall uses Particle/Alpha Blend. when I add ZWrite On it's no longer a waterfall. gets so dark.

Ok, here is how I solved the problem.

I used Queue in tags like this:

Tags { "Queue" = "Transparent+1" }

This will relatively render the object on top of other transparent objects.
