Hey Just … WebThe 2xN image is now your signed distance field for all four quadrants of the light (remember that one quadrant is basically a single camera frustum at 90 degrees). Render the lightmap. Blur the lightmap (based on the distance from the light) so that you get soft shadows. My final implementation was (each step being a single shader): Do (1).

WebApr 24, 2024 · Small (M)SDF font textures have artefacts. I am testing some font rendering with Multi-channel signed distance fields (MSDF).
