I managed to get the textures to stop flashing but this looks more like a lighting issue. I'm using CoT, RLO, and RealVision ENB. Does anyone know how I can fix this? It only does this when I turn on UseOriginalObjectsProcessing in the ENB menu. How do I get that option to actually work properly?

You'd maybe have better luck asking on the RealVision ENB page?

Why are you using Original Object Processing? That effectively turns off the ENB and it will default to vanilla lighting, which as you noticed is severely lacking.

Because without it, the colors are too bright and with it on the colors actually look good. The grass especially.

Then do not use the ENB. Maybe just use ENB Boost.
