    Hello!

    I have several semi transparent planes that at times overlap and I'm trying to achieve this effect:

    $Maxh8.png

    ...rather than what it's doing right now (using the Transparet/Diffuse shader) which is this:

    $5610-untitled-2.png

    Is this possible using shaders?

    Regards/Per

    No... Well, not easily. You could mark every pixel where such an object renders with stencil, so that you don't render another one at the same place.

    Have the same question. Maybe bringing it up would help?

    It sounds like you want to render a bunch of opaque things to a render texture, and then composite that semitransparently to your scene.

    No. Render textures are a Pro feature.
