Before starting creating any models, we will first need to cover which of the programs to use for importing and working with Bloodlines / Source models. Luckily we have a few selection of programs to choose from. As a bit of side note, as there are no working way to decompile the original Vampire the Masquerade: Bloodlines models, these tools should get you ready for when it happens. We got confirmation that Crowbar, the most recent Source model decompiler, will be able to decompile the original models in the next update.
