WebGLBindingStates setupVertexAttributes BUG #20196
Description
When I use the scene with both InstancedMesh and normal Mesh, and set the scene.overrideMaterial =Depthmaterial; then object.instanceMatrix Is the undefined value, because normal Mesh does not have this property. In the setupVertexAttributes method of WebGLBindingStates, const attribute= attributes.get(object.instanceMatrix) On line 386, an exception is thrown. It is suggested to modify the get method of WebGLAttributes and add judgment:
function get(attribute) {
if (attribute === undefined) {
return undefined;
}
if ( attribute.isInterleavedBufferAttribute ) { attribute = attribute.data ;}
return buffers.get ( attribute );
}
