Hmm weird, I guess I will have to explore the source code.
If you have some spare time, could you explain how does the planar reflection actor work?
I can’t say I understand why it needs to update every frame :p… what if the camera is stationary? there is that scenario too (we could render at half framerate when the camera isn’t moving).
And as I understand it, it doesn’t need to read outside the rendered region either but instead use the camera position/rotation that it was rendered at (like I said, this can result in slightly unaligned reflections but it works fairly well in GTAV).
Thanks for the reply!
