Hi! There is no way to do that. But if you are willing, you can create your own new entities.There are very few modders that do that, so any new addition will be great!

You can ask @Logics to provide you a Blender template scene for the objects in game. He is behind the Project-X mods.

Also there is a guide about importing entities from @kkroasan

Thanks, I'll continue down that route.. just getting errors from the exporter tool when I'm actually trying to make a new asset.

I've also been trying to do something like this. I really want to make new walls and roofs and things. I got a flooring to work pretty nicely, but I'm having a lot of trouble with walls. No matter what I do they still use the original wall model and my custom model just gets slapped on top of it. I have been scouring anything I can find to try and figure it out.
