CSS fonts

Use a font converter like transfonter:

Upload all fonts
Enter subset (usually latin, can also copy/paste your specific subset if needed, saves a lot of weight)
Woff/woff2
(Optionally) if the exported font has issues, try a different hinting param

WebGL fonts

Convert fonts to msdf format in a single texture and compress them

Install msdf-bmfont-xml from npm

I'm learning unity by redoing old projects or scenes of videogames (coming from a webGL background), and documenting things I get stuck on, as well as findings.

OpenUPM (and other UPM)

Basically npm for Unity. Just need to add dependencies and scopedRegistries to Packages/manifest.json, Unity will detect the change and install the package.

Importing upm packages in a shader (ShaderLab)

Add this line in CGPROGRAM, after #include "UnityCG.cginc":

#include "Packages/jp.keijiro.noiseshader/Shader/SimplexNoise2D.hlsl"

img sequence to mp4

ffmpeg -framerate <fps> -pattern_type glob -i "*.jpg" -c:v libx264 -r 30 -pix_fmt yuv420p output.mp4 where 24 is the desired fps

mov to mp4

ffmpeg -i input.mov -vcodec h264 -acodec mp2 output.mp4

mp4 to gif
