applyMatrix not applied on morphAttributes?

When I apply a matrix on a bufferGeometry using applyMatrix(), it does not apply the matrix on the morphAttributes of that geometry.

How do I apply it on the morphAttributes?

You can call matrix.applyToBufferAttribute(...) on each attribute used in your morph targets: https://threejs.org/docs/#api/en/math/Matrix4.applyToBufferAttribute

Thanks, that works well and is easier than the temporary solution I tried…
