Quick question for everyone...when creating an interior game level... (in my case, in a sewer)
in general, do the corners/bends in the mesh need to have the vertex's welded?

i'm talking about those i have selected in the above image.... and also around the doorways, etc...

because a base scanline render of it, in 3ds, it all flows smooth, and doesn't look right (no texture created for it yet, so i'm not sure if applying a texture to it would fix what i'm talking about or not) any ideas?

Can't see the picture. If you find it all smooths together with the verts welded, then you need to look into assigning smoothing groups.

As for what a game engine needs, that varies a bit, but usually it's best to weld everything if you can. Separate objects obviously won't be smoothed together and can't have their verts welded, but within a single object, yes usually it's best.

However the exporter might well break the verts again as it will need to do that to define which polygon has which texture on it. If you have two materials/textures on adjacent polygons, but the shared verts are welded, that's not allowed by most game engines, so it will duplicate those verts and make two separate quads. But usually you don't need to worry about that sort of thing.
