UPDATED: see my response below...     Hi,    I have problem with performance when rendering into RenderTexture. First I will describe my scene:      I have two images/textures with 512x512 dimensions. I have on RenderTexture with size 640x640 I generate random curve on this RenderTexture. Then I use this generated RenderTexture as sprite which I put onto screen. Finally I add additional sprites to complete scene.    Because the curve in Rendertexture has to be filled from both sides with images
