Hello. Sorry, my first post here, I’ll be careful next time.
The project is all mine, it’s not even a game or anything fancy. I just opened the starting empty scene, removed the furniture, added my fbx model from Modo, fixed all the textures / surfaces, removed collision from my mesh and added some hidden primitive (that works fine) and I’m just able to move around my scene, which (for now) is all I need to visit the room.
So, no BluePrint or C++ or plugins. Not even sure you can be more basic that this.
I’m going to try to re-install visual studio (just did this morning) and see if that fixes the problem.
Thank you for your answer.
