Clarification with Texture2D.ReadPixels.
Just want to clarify with ReadPixels. I have a plane with a few materials on its surface, and I want to use ReadPixels from a camera (hidden; doesn't show up on-screen) on this plane. Effectively, it'd give me a single image to match the plane.
Is this how to use it? And I wouldn't need Unity Pro? (Note: It's just a snapshot; not actually using it as a Render Texture like the Unity Pro feature.)
No, if you don't read from a rendertexture, then you're reading from what's actually on the screen. Using a rendertexture is the only way to do that with a "hidden" camera.
I see. Thanks!
Though, I do wonder whether it might be possible to, during LateUpdate, switch the camera on to render, then switch it back off really quick before it's rendered?
No, in order to read pixels they have to be rendered to the screen. (Or a rendertexture.)
