Hi,
The shader properties for playcanvas have changed in latest engine update - if you could please update this function
this is the fix required below
xrcontroller.prototype.makeShadowMaterial = function({ pc, material }) {
const n = material.resource || material
n.chunks.APIVersion = pc.CHUNKAPI_1_65
n.chunks.endPS = "\n litArgs_opacity = mix(light0_shadowIntensity, 0.0, shadow0);\n gl_FragColor.rgb = vec3(0.0);\n "
n.blendType = pc.BLEND_PREMULTIPLIED
n.update()
}
Thanks
