Hi guys. I’m loading a model from 3ds max using ThreeJSExporter.ms. Ok, model and texture loads but the mesh is not smoothed. Is there a way to smooth a loaded model?

The model must be smoothed in the editor. If it was smoothed, it wouldn’t seem like the model, and would take a lot of memory up.

Try doing `geometry.computeVertexNormals()`.

It’s smoothed in 3DS Max. I needed to smooth it in three js.
