PBR to Source converter (.blend) - A Mod for Source Engine.

A tool to update source textures!

so, you have PBR materials- maybe they are from source 2, maybe you made them yourself, or maybe they came from the internet somewhere.

Have you ever wanted to convert your pbr materials to work with source engine 1?
This'll help you!

I created this based on (and improved apon) another tool I've used for this exact purpose for a long time; and I figured it'd be nice to share for people who want better materials on their models.

NOTE: This doesn't create True PBR or create textures from scratch, it assumes you already have pbr textures (metallic workflow) for a model and all it does is convert them to a format that mimicks the same look fairly well in source engine.

Feel free to use this, but please always give me credit in the following format:

I would also highly appreciate if you send me a link to where you've used this. :)
