This is probably a dumb question, but is there a way to turn a color transparent on a texture. For example if you create a blue background with a red circle in the middle.
Can you turn that blue transparent so you only see the circle?
I know you can have transparent textures. If you load a image that already has alpha on it, but I'm not sure if you can turn a texture color transparent after its been created or loaded.
I do this with sprites all the time, but I've never seen it done with textures.

First, I have no idea about what's possible with PB's engine, I never used it and I will never use it.
However if I wanted to do what you describe, I'd use a pixel shader to change the colors.

Look at CreateTexture2.pb in your folder Examples\3D. It does exactly what you are looking for.

or here if you need to play with shaders.

Thank you, Comtois. That example was exactly what I was looking for.
I thought I looked through all the examples, but I guess I'm blind because I don't remember seeing that one.
