Fixed the problem completely. I will try uploading the game to see what happens, but now the build seems to work nicely.
What I did at first was change from the regular model.material, to the model.material in the render folder that I took from the Tans VS Meteors Project, but it turned out to only partly fix the problems and the lights didn’t work as well as they should…
But doing what @sven wrote here worked perfectly, model rendered well and with correct lighting.
Thank you 
@sicher Hey I saw your post about tutorials and how 3D is definitely planned, just wanted to mention this what sven posted here could be added to it
Cheers!
