I will be releasing guides as Works In Progress and updating them as I go. I've decided to go with a Series of guides because there is just too much information to pass on and if I wait for this to be complete before releasing, we'll be using Blender 3.0.
This will be a series of guides that will be dedicated to the modelling processes required to take a model from Blender, be it a build from scratch, imported FBX, XNA Lara, MMD, Valve MDL/SMD/DMX, OBJ, DAE, PSK, PSKX or whatever format that is currently imported in to Blender and covert it to a usable prop, misc, character model asset to be used in the Source (TF2) version of SFM.
