So I'm a beginner at blender and I need to make a wooden structure for a catapult. I'm wondering if evey beams needs to be a separate obect or all on one single obects.
If they should be separate, should i delete the non visible faces and so make the beams hollow?
If everything should be on one obect, wouldn't it be too difficult for the UV unwrap?

After that i'll have to texture it on adobe 3d painter and then import it on unreal engine
