Descrição
Hello,Sorry for my english,I have 2 methods for rendering reflection of water. On the screenshot you can see cubemap and screen space reflection. If I use cubmap then I get the correct image. For flat reflections(ssr/planar), I always see the formulatex2D (reflectionTex, screenPos.xy + normal.xz);in
