As the title suggests, when using a particle system on an avatar, attempting to upload it when the particle material uses Alpha Blended results in the SDK refusing to upload, indicating it is an "unsupported" shader.
Then tells us to use shaders from
VRChat/Mobile
…which is where this very shader is from.
This is objectively bad. Either move the AlphaBlended shader
out
of
VRChat/Mobile
(E.G.
VRChat/PC
), or whitelist AlphaBlended on Quest
when used with a particle system.
SDK version 3.8.2

Notes
  • Fax says that transparency is not supported on Quest, hence its refusal to upload, but this is actually not true. Transparency is not supported
    on mesh renderers only.
    Particle systems do support transparency.
