Yeah, I’ve been trying to get to the bottom of this, but I can’t for the life of me link the debug physx code with ue4. This makes stepping through it nigh impossible. I need to do this in order to see where everything comes into play in physX code. As it stands now I can’t tell if the changes I make have any lasting effect, which is infuriating. Part of the problem is due to the fact that the whole setup for dll placement has to do with the VS version. This complicates issues because I’m compiling UE4 in VS2015, as well as compiling the PhysX in VS2015, but UE4 only has it listed as being compiled in VS2013, but has precompiled dlls for PhysX from VS2015. I’ve tried changing the location and outputs of file types, to try and replace them, but everything I do breaks UE4, all the way to the point that I had to redownload and recompile the whole engine. But I haven’t my engine successfully compile since. These problems are very disheartening.
