Merge actors vs one model

Hello guys,

I have a question about merge actors in Unreal Engine 4. I created model of one step of stairs and I wonder what is better for optimization in engine. I created one model with for example twenty steps and i merge this into one mesh in my modeling software or better is creating one step of stairs, export this model with material and then merge this 20 steps into one in Unreal Engine. is there any difference when looking for optimization?

It doesnt make a difference as long as the triangle count is the same, but I advise you do your modeling work in your modeling software then export to Unreal Engine. After that you can optimize using Unreal’s LOD system.

Ok, I will follow your advice. Thank you :slight_smile:
