It’s a good question, not a silly one, and you are correct in your understanding of how light interacts.
Short answer: No!
Little longer answer:
I think, like most, there is a misunderstanding of the process of exporting a model, and where we find the answer.
Let’s try and understand exporting first.
Many people when learning, think exporting a model means using one model and it’s materials in different software, Blender and Unreal for example.
Exporting, simply put, is basically saving the model from Blender as a specific file type to use in Unreal.
The Blender model (.blend) still exists, a new file (.fbx for example) is created and saved for use in Unreal.
You could think of it as a duplicate model.
However to answer your question on the bevel node,
The bevel node is a Blender shader node, it and all other nodes only work in Blender.
However, to export the model to a game engine, you first need to UV unwrap and bake out texture and normal maps.
UV’s and texture maps can be thought of in the same way, saving to a specific format to use in other software.
I hope this makes sense!
