i think i’ve found it, it is not vertexColors={THREE.VertexColors} any longer but just a boolean now: <...material vertexColors />. not sure when that change was even made, i still see examples on google using the old syntax but i find no explanation.
edit:
but still no idea why it starts to make a problem between 140 and 142
Starting with r141 the project starts to keep legacy code for only ten releases. We have used this as an opportunity to remove all code which was deprecated up to r130.
That means the previous constants THREE.NoColors, THREE.FaceColors and THREE.VertexColors have finally be removed and it’s required to use a boolean now.
