Crash in WebGPU: Error: no matching constructor for vec4 about three.js HOT 7 CLOSED

I'm preparing a PR that I think will solve this issue as part of its changes. (It's quite a large PR so maybe will take a week or two to finish it)

from three.js.

I now think you can solve the issue just by changing attribute( 'color' ) in the line

Yes, this change worked correctly! Thank you. I can make a PR with this change now.

The error message is about the variable DiffuseColor, and that there is some exception assigning this variable.

DiffuseColor is for example mentioned here in the Three.js source code:

@LeviPesin Excellent. Do you understand what causes the error in this case? Is there some work-around quick-fix I can try? Thank you!

from three.js.

Possibly your geometry has a color attribute (i.e. storing vertex colors), which is of type vec4, not vec3 (it should be auto-converted to vec3, but if not, that's a bug)? So as a workaround I would suggest changing it to vec3.

from three.js.

How can I modify the code to get a more accurate error message? How can I get a stacktrace from this? Can I find out which geometry is causing this? There are many models loaded from glTF, so possibly some of these models have color attributes?
