MSAA?

[VinnyVicious]

Results are very noisy without any filtering. Is it possible to add MSAA to this rendering technique?

It looks like your textures don't have mipmaps. MSAA only helps with anti-aliasing along triangle edges.

But yes, you can enable MSAA by creating the intermediate framebuffer attachments with MSAA. Try adding BGFX_TEXTURE_RT_MSAA_X4 to the createTexture2D() calls here:

Cluster/src/Renderer/Renderer.cpp

Line 221 in a25ff32

bgfx::FrameBufferHandle Renderer::createFrameBuffer(bool hdr, bool depth)

(Note: This won't work correctly for the deferred renderer, you'd need some post-process anti-aliasing there)

Oh, that does the trick:

Thank you, you're a genius. :)
