• WARNING: Model has 2-dimensional geometry

Spent like 4 hours searching and trying to solve the solution but can't seem to figure out what the problem is. WARNING: Model has 2-dimensional geometry (less than 0.500 inches thick on any axis)!!! WARNING: Error with convex elements of ff_arch_brace_physics.smd, building single convex!!!!     Model has 6 convex sub-parts That's right at the end of where it build the collisions. I built a collision mesh from a cube in Blender and traced the model I'm trying to import by duplicating edges and vertices then just hitting F after selecting some of the edges/verts to construct a face. I've got no idea what the problem as as all the vertexes are weighted to the bone, they are all in the same vertex grouping, the model is fairly large (large enough for someone to stand in it) so it can't be vertices too close.
should post the model for us to take a look at
https://i.imgur.com/idKEKRB.png https://i.imgur.com/zz3N1ch.png I'm trying to work on a Reach forge prop model pack, I know the mesh is not too complex either. Just I don't know why it does this, I can't even add a simple cube as a collision mesh without it spitting these errors out.
Is this the colission mesh? That's not how colission works. You gotta use convex shapes.As much i can pin there. https://i.imgur.com/rHGOVZ0.jpg
bshadow is right, but to expand to his responde, the model had no 2d geometry, that's the message you get when collision mesh is not done properly. In the source engine, the collisions themselves are only simple convex shapes, to make them concave you use multiple convexes. This thread might be useful, it explains how to do a collision mesh properly: Just ported a model but 2 issues occured If you need a cryptic "official" explanation you can read up the valve page about it: Collision mesh Also, I know it's stupid, but I had to do this at least once when I was having the same problem, it helps to look up what exactly a concave shape is, because when you compare the actual meaning to your model, you can start to see the problems. Note that a convex shape doesn't have to be simple, if you are smart with it, you can use a single convex with a complex shape to reduce the number of vertices, don't think that you did the physics wrong because the .SMD is bigger than the actual model, it happens often since collision meshes have strict rules to follow, the model themselves don't.
I went through everything manually, still said I had errors, I used Blenders clean up to remove convex shapes and still getting errors. In fact it says there are now 8 convex subparts now.
Make sure your mesh and mesh parts are all single convex smooth meshes. Like this bunny collision. Does it have a gun on it's head? lol https://i.imgur.com/lRz4mXv.jpg
Nah, it’s a forge piece from Halo Reach. I wanna create a pack of Halo Reach forge props for building, but I’m just stuck on collisions. I know how to do everything else.
I'm still having issues finding out what the problem is. I can't even create two simple quadrilaterals without giving me the same error. All I did was create cubes and move them into place. https://i.imgur.com/0xqGnKW.png       WARNING: Model has 2-dimensional geometry (less than 0.500 inches thick on any axis)!!!       WARNING: Error with convex elements of ff_arch_brace_physics.smd, building single convex!!!!       Model has 1 convex sub-parts       Collision model completed.
