I have to render a scene, once per light, and blend the result of the various passes. I heard and read that one way to increase performances and Render Targets to use would be Ping Poing.

Since I am a bit of a newbie in the context, can you explain a bit more such idea to me (in terms of Render targets + blending in my situation)

Thank you very much I really appreciate any type of help

I have to render a scene, once per light, and blend the result of the various passes. I heard and read that one way to increase performances and render targets to use would be ping pong.

I'm new to this context. What does this mean in terms of render targets + blending?
