I was wondering if anyone knew how to render multiple frames from a camera or texture to a buffer in Unity and to then blend them together? Is this possible? If so how would I go about doing so in Unity?
The Image Effects source code should give you a good idea how to render into a render target. You can import the package and look through the source code to get an idea of how they happen.
The basics are:
- render a quad that covers the full size of the render target
- the shader does the blending you're talking about by using the previous render target texture(s) as input
- the output goes into a new render target, which can then be used as input for the next
