I don't think this is expressly forbidden in the spec, but @lexaknyazev, you'd probably know better than I would. \r\n\r\nOn the other side of that, there's also `nodeViewportMatrix` which is `VIEWPORT` and a `VEC4`, which I'd say the validator is correct and that shouldn't be allowed.\r\n\r\nEdit: I'm also not sure if this is a validator issue or something we shouldn't be doing that needs to be/is already being tightened up in the spec"}}
