Seems to be an issue with the mesh creation in shaded display here. In v5 as soon as an object is in view in shaded display the mesh automatically generates. I’m finding I have to click the object before it will generate.
Check run. Poly surface is valid. I’ve had this issue with a number of imports. It seems when the imported object imports out of view this happens. If the object imports into view then it meshes automatically (as it does in v5).
If objects come into the file out of the view and the view is shaded, it is normal that they may not shade until they are in the view but it should not require a selection - I’ll see if I can reproduce that … I can -
