This tutorial is amazing, there is only 2 things i'd like to point out, - When trying to port source 1 models, you haven't explained how to get the .vtf source texture files into .png or some equivalent, For that, you can use VTFEdit, a free tool that lets you convert in bulk these type of files. You can then use the .png file like explained in the tutorial. - CATS addon for blender is not supported in blender versions 5.1 and above, thus if you have the tilted head problem and want to fix it, there is this tool that seems to work in blender 5.1 and just does that https://github.com/InconsolableCellist/ApplyPoseAsRestPose Thank you for your work, this ressource is amazing !
