Is Merging Meshes In UE4 a Bad Practice?

Hello I am just wondering if merging my static meshes such as walls is classed as bad practice within game development? I’m just wondering if this causes extra tress on game performance? Thanks :slight_smile:

Hi Nickmadd,

Combining Meshes on import is common practice. For instance if you are importing a building with the walls, floor, ceiling, doors, and windows all as separate meshes in your 3D program. You can combine them on import and they will be one mesh but they will be on different Material Elements so you can texture them correctly. In this situation, this method is much more efficient than importing them all separately.

Please take a look at the link below for more info on the static mesh pipeline.

Thanks, TJ

Yeah but when You use Actor Merging You decrease the Lightmaps quallity? With is equal to increase build time. Am i wrong?
