I’ve am workin on this map for about a month now , and it mostly consists of modular meshes .
So i saved the level , went for a 30 min break , after i come back , now it gives me this error 100% of the times when i try to open my level.
i’m using the 4.3 release version of the engine , and the map file which crashes is about 10 mb .
i really cant understand what is causing this problem , and here is a picture showing the error. second attachment is the dump file and log file zipped in one[link text][1].
Please understand that i put “a lot” of effort and time in this level i cant really let it go to waste

I noticed in the first line of the error , it says collision .
In fact i was actually working with collision before i save the project and quit the engine . but :
- all the collisions i made were inside the engine , didnt import any collision primitive .
- i only used the box and capsule collision primitives.
- only used 1 collision primitive per mesh so no overlapping collisions.
- i didnt move the collision.
i remember that 4.3 got a huge update to collision , could it be the cause of the problem ?
in the mean time i go and play with collisions to see if in fact it is the source of the problem.
I took a quick look at that code and it’s attempting to load cooked data out of the DDC, which for some reason may have become corrupted. Try deleting your DDC file (it’s a cached set of cooked data based on your assets) it will just get regenerated the next time you run.
ex: C:\Program Files\Unreal Engine\4.3\Engine\DerivedDataCache\DDC.ddp
If that doesn’t work and If you’re sharing a DDC over the local network you may want to try running with, -ddc=noshared on the command line when loading the editor.

i pinpointed the problem . it is in fact collision .
I started to remove the collisions which i last applied to meshes , and i see that whenever i click on the meshes with " Capsule collision primitive " it crashes the editor .
it ONLY happens on the meshes with capsule primitive , all the other primitives are fine .
I deleted the .uasset file from the project folder (i couldnt delete it inside the engine. everytime i click on it , editor crashes ) . i reimported the same mesh , this time with custom primitive made in maya . now everything works again .
btw i didnt delete the DCC file , and i’m not sharing the DDC over a local network.
