Hi!
When setting Renderer 1 “AA Samples per pixels” to 32, the topmost shape becomes smooth. However, when trying to use its output as a texture, it becomes pixelated again, despite enabling the same setting on renderer 2.
I don’t know anything about graphics programming for the time being, so troubleshooting is a bit difficult.
I’m using DX11, by the way - I couldn’t find a way to achieve smooth shapes with DX9.
