Fixed #24357.
Description
It seems there are exporters like the one from Cinema4D which might export FBX assets with negative material indices. I have found no official documentation about valid values of the FBX field
LayerElementMaterial.Materials.a
. However, negative values are not supported inthree.js
.The loader now reports a warning when negative material indices are detected and uses
0
instead.Just want to note that an asset with missing material definitions is a model authoring error and should be fixed in a DCC tool.
