textures are blending with an orthographic camera

I hope I’m not breaking protocol by posting here. I’ve posted this in the support forum, but the responses seem more frequent here…

I’m setting up a simple game with an orthographic camera. The background and overlaid sprite use plane meshes. When I use an orthographic camera, the textures for the two objects are blending. If I switch the sprite to a cube mesh with a very small z dimension, it works.

But shouldn’t I be able to use planes for everything in an orthographic world? How do I prevent this texture blending?

Thanks,

What shader are you using for the sprite materials?

I tried the default “diffuse” shader and a few others. I played with the settings but it didn’t seem to make a difference.

Are the two planes exactly on top of each other or is one closer to the camera? Two objects in the same position will tend to “fight” each other from a rendering point of view and you’ll get pixels from both.

Yes, they were exactly on top of each other. I resolved it by separating them. This is a paradox with orthographic cameras though - changing their z position has no effect on what is shown, but changing the z positions of game objects does. I guess the way to think of z position in an orthographic scene is more like layers than actual position.
