Advanced 3D Shadow Casts Only on One 3D Object; Other One Not Working

[DizainoKoma]

I'm working on a project with multiple 3D objects. I created a shadow with a solid for one 3D object (the red one), and it worked perfectly. However, when I tried the same method with a different 3D object, the solid just doesn't recognize it. Any ideas on what the problem could be?

Nevermind. The other 3D object gbl files didn't have "cast shadows" turned on. Sorry.
