[Closed] SwarmAgent problems UE (trying to invert a NIL matrix)
Hi I'm trying to port our project from 4.7 to 4.8, I have fixed some c++ errors and now it compiles and I can play the game.
The problem is that all previously generated lightmaps seems to be broken, so I decided to recompile lights.
The swarm agent starts but in the "Lightmass Starting" process this error appears in the log:
After this, the build process ends but there is no crash.
What can I do to solve this?
I have launched the engine in DebugGame configuration and this breakpoint is reached in the gathering scene geometry process:
I think that this is a problem with some foliage mesh, becouse I don´t use any instanced static meshes directly in my project.
I have tried to compile in an empty map with some foliage meshes and it works.
I will keep investigating but It would be nice some help please.

The question is answered, right answer was accepted
At the end I achieved to fix this issue by changing this lines in UnrealMatrix.h:
This is what the Inverse() functions does inside, after this I recompiled the editor and the unreal Lightmasss and it worked fine.
