You aren’t making much sense on this one…
For one, the image you shared is literally just any animation you drop in the abp without any changes.
And secondly, cached poses come with their own cost.
While I would suggest splitting standing and crouched into different caches if it serves a specific purpose, the less amount of overall cached poses you have the better off character performance is.
Particularly when you start to have a significant amount of characters that use the ABP. Think a Mount n Blade situation with an army of 400plus.
