I’d like to add a couple of more variable types (such as material instances and sounds) to the default PhysicalMaterial.h file so that I could retrieve them after shooting an object, for example, and use them to spawn sounds, bullet hole decals, etc. instead of having to look for the physical material in a library and then retrieving the variables from there as it would be a lot easier and better for performance to add the variables directly to the PhysicalMaterial.h class.
The problem is that if I add any variables that are not simple floats, booleans, integers, etc. I cannot compile the engine. I get all kinds of errors.
I’ve tried including the EngineTypes.h.h and Actor.h files in the PhysicalMaterial.h, but it didn’t help.
Is it possible to add any other variables, such as sounds, to the PhysicalMaterial.h file, or am I wasting my time?
You can add is the short answerr but why you want to do them in that ? Still if you show the compilation error we can take a look. I bet it needs physicscore.
What I would recommend though in terrms of this mechanics.
Make a base impact class that is spawned on a valid impact and just gets hit data from projectile or hitscan.
And on that class you can branch your things like sounds, decals, phsyics volumes, vfx and whatver rather than doing it in physical material .h
This way actually is very nice even if you want to push forward you can use that for footsteps, punches in the game which I do also, so you don’t have to think later on what happens when you hit/impact something, it becomes a logical container.
Upon compilation I get hundreds of errors from the seemingly unrelated files, mainly from InputCoreTypes.h.
I’ll post them here but the list is very long.

I tried making a child class of PhysicalMaterial.h, but the engine does not allow you to reparent physical material assets or create new ones based on that class, so you can’t assign them to your meshes.
So I was able to add some variables to PhysicalMaterial.h . I also tried to add something more complex like a MaterialInterface as you do with include “Materials/MaterialInterface.h”
reference to it and had no problems (with my limited knowledge)
Also you need to add Engine dependency to PhysicsCore.Build.cs or if there is a dependency.
When I directly edited the builded engine code however I get errors similar to your output, however when I build the engine from source have no issues as modified engine.
This being said, I would like to give a heads up for couple of things, just as opinion.
As logic I would expect here to have phsyics properties and coralated things as another class, like sound etc.
However If I was building a physics related feature in Engine, let’s say Sound Propagation which is coralated with porosity and density I would expect it to be listed here. That is a nice feature important for some of the competetive games like Siege. Can be many other physical properties like hardness etc. not subject of the this thread.
Or let’s say I want to build a new physics feature as Heat Dispersion. I would expect to see Heat Dispersion Coefficient to be here as well as melting point , freezing point etc. So in future I can add that to world landscape material and if there is a heatsource in game like a fireplace, I can do various things with physics like: melting snow, increasing the damage received from fire with distance, changing material visual effects like red hot metal etc. gameplay mechanics, like make stamina drain faster if you are in a very cold zone Many possibilities so it creates even more believable world with minimal effort.
However I would not expect to see a SoundFile, as physical material property, however can be if you need to, Imo those can be another class.
Let me know if this was helpfull.
PS: Thanks also your question push me to make space and time for building the source in my local development space.
Many possibilities so it creates even more believable world with minimal effort.
