Texture vs Mesh

siejang · Oct 2018

Hi,
I'm making an environment scene, and I'm using PBR and 2k maps for my scene.

I wonder which way is better to optimize my scene for game engine. Which one is more heavier? Texture map? Or More Meshes?

Anyone knows tutorial or website that I can check for optimization of my environment scene?

Any help will be great!

Thank you.

Run a profiler in-game, see whether you're Transform-bound (generally vertices) or Fillrate-bound (generally materials).

In practice tho it's hella more complicated.

This depends on what game engine you are using. Does the game engine have texture streaming? does the game engine have streaming geometry? There are game engines that have both of these things and some have neither - but they'll both change the way you build assets and construct scenes.

I'm using Unreal 4 engine now.

Download some of the content on the asset store from Paragon and have a look at how they're made. This will give you an idea of the kind of polycounts and texture sizes that are reasonable.

There are also lots and lots of tutorials and documentation for Unreal:
