I recently made a small demo that reads an STL file from the always awesome thingiverse and creates a model in Unreal. Note that it reads the file directly from Thingiverse, not from the local drive.
At present, it’s only working with simple models- more R&D will be required to get it working with more complex models.
The model in the screenshot is the awesome “Low Poly Fox” by Thingiverse user slavikk.
