-**Before submitting a bug**
-
-It is fairly common that loading issues are produced by malformed glTF files, so YOU MUST check the model you're trying to load with glTF Validator before submitting a bug report.
-
-    https://github.khronos.org/glTF-Validator
-
-- If glTF Validator reports the model has errors, then you must report the problem to the owner of the exporter, _not here_.
-- If glTF Validator reports no errors, then you can proceed to report the issue here.
