THREE.BufferGeometryUtils.toTrianglesDrawMode problem

Questions

Hello everyone !
I’ve a problem with the new version of three.js. After that to my mesh I always do .drawMode but not is unavaible so I tried to use console.log(new THREE.BufferGeometryUtils.toTrianglesDrawMode(this.mesh.geometry, THREE.TriangleStripDrawMode)); but when I do that with TriangleStripDrawMode I’ve this error log
TypeError: attribute.clone is not a function
at BufferGeometry.copy (three2.js:11075)
at SurfaceGeometry.clone (three2.js:11036)
And attribute.clone is on three.js file line 11075
If somenone know why !

Maybe because the attribute is of type InterleavedBufferAttribute? This class has no clone() method so far.

Yes that’s right so you can’t use THREE.BufferGeometryUtils.toTrianglesDrawMode with TriangleStripDrawMode or you have to remove in threeJs the .clone …

Well, the workaround is the de-interleave the buffer data before using BufferGeometryUtils.toTrianglesDrawMode() for now.
