Seeing the QC would help in diagnosing the problem, as a temporary solution thought you could just disable the solidity and draw clip brushes manually around it.
Edit: actually I just realized what's probably the problem, the QC key $concave probably didn't get decompiled, add that to the collision models properties.
While you are correct, so I won't dislike your post, it's not really relevant as scaled dynamic props don't display in hammer nor would scaling it create the issue in the screenshot of the OP.
Blinx is correct, the collision model has been recompiled using the shrink wrap method which can be caused by a few things. Considering it's a decompiled model, it is likely $concave missing in the $collisionmodel {} part of the QC. If that doesn't work, you will need to manually edit the collision model in a modelling software.
Here is the QC file, it looks like i will have to edit the collision manually. I decompiled the original model (mp_capbottom.mdl) via Crowbar, edited the $ModelName and $scale. If there is any thing anyone can gather from this, I'd appreciate the input. Thanks for the responses so far, I appreciate all of you taking your time to respond!
