Description
This PR closes #93537 and closes #94515 .
When using
textureProjwithsampler2DShadow, there is a bug in ANGLE on MacOS browsers(https://issues.angleproject.org/issues/354101888), causing directional shadows to not work. This issue is resolved by replacing textureProj with textureProjLod, which functions correctly.UPDATE: It was marked as fixed in Chromium 130.0.6697.0.
