I was able to export the model and get it into a clean project in 4.3 preview that’s available from the launcher.
I went into the mesh viewer and was able to edit the scale.The model is such a large scale though that it the scaling moves at such a slow rate.
I do notice that the scaling speed is completely different from the box/sphere collision and the DOP-simplified collision, which could probably use some improvements, especially with a model this scale.
