Brawny for sleeves, lean for no sleeves.
The veil won't appear on armory and menus unless you use Apofes' Advanced Shader Mod.
Two versions. The optimized one has lesser model polygons than the unoptimized, which lessens the performance impact on your game. There's no noticeable difference between the two until you set the object detail quality setting to Low.
Noticeable difference when Object Detail Quality is set to low(applies only to Optimized Version).
1. When down on planets, the lower tier Level of Detail of the mod will kick in even when up close, where the quality of the model is degraded.
Optimized version is to make the game not fully render the model when viewed from a distance. This is done to reduce resource consumption of the game (especially VRAM).
Installation: extract in your helldivers 2 data folder (rename patch_0 to patch_1 and so on if you have existing files with the same name) or use mod manager.
