I want to adjust the texture of the slabs of beef, venison, etc. in-game, because it looks strange walking around houses and seeing raw meat on people's plates and on the cooking grills in the fireplaces. The question is, how do I find the name of the texture, when everything's packaged into those BSA files?

(oops, this should have gone in the mod section...sorry about that)

You have to extract the contents of a BSA file using BSA Commander first. In this case the files would be under Textures/Clutter, with names like IngredVenisonSteak01.

Thank you for the info. Here's the result:

Well done, Tchos.
