How best to optimisie these meshes?

[EdBennett]

I’m working on a tool which helps me layout rooms by using 400x400 planes. It’s working well but I was hoping I could get some advice around how to optimise this so at run time it works well.

Now say for example I have a 2 by 4 group of these static meshes to make a wall like this:

Now for optimisation I have a couple of options that I can think of:

1: Calculate each the dimension of the group and then replace with one static mesh scaled to fit the area.
2: Use the actor merge to make one static mesh.

Now my preference would be to do 2 since I think it would be simpler also my hope is it might allow me to do more complicated shapes like entire rooms bakes into one static mesh.

However I’m not sure what the overheads would be like. It would mean I would need to create a unique static mesh for every single room. Also I’m not sure merge actually reduces the amount of vertices.

If I’m make 20 call of the same static mesh is that less than say 2 call to 2 different meshes?

Speaking theoretically . Isn’t it more efficient to have the first option. Have one static mesh which can be instanced to generate a complicated object . If you have a complicated mesh made of many instances of the mesh then it works out to be more efficient than one large static mesh. This way reduces the number of draw calls . Somebody correct me if I’m wrong
