Thanks for this update, but unfortunately I have the very same problem as the user "Blade" has.
I got a single model in a scene with blocks but it is not visible.
It has no texture file as skin but a skin defined as "skin1" including a material set-up. In MED it is rendered as green, like it should.
But when I run the level from SED it is not visible, the statistic panel however lists one entity and one visible entity which must be it.
Other facts:
- entity is created via ent_create and gets a simple action attach which just sets a pointer to it
- nothing else

any suggestions?
(yes in the prior version it worked just fine)
