I got sick of seeing people rotate brush work crates, only for the textures to mess up. And forget resizing, as you’ll have to retexture each side.
So, I made each crate (5 in all), and exported them as ASEs.
You can get them here: http://www.hummerdesign.com/prefabs/crates/hummer_crates.zip
When you use them, set the spawnflags to 2, so they are clipped. They’ll make the wood sound too, since they’re using the crate shaders anyway.
Crates are now easy to resize, rotate, etc. They’re aligned to the grid as well, so the’ll match other crates you have. However, all sides have textures, so if you’re doing a row of crates, don’t use these models… these should really be used for accent pieces
