I am really new in 3d Rendering and like.
I've generated .stl mesh files using Fiji/ImageJ. I imported them in 3dSlicer and I can see them.
When I'd tried in Blender (hoping to have nicer rendering options), they are imported but I cannot see them anywhere.
Here is an example of the .stl
Here a rendering of the .stl with 3dSlicer:

This is what I (don't) see in Blender

What am I doing wrong?
