Tired of the many basic attempts at creating an Overgrown version of the Portal 1 aesthetic? The Flawol Overgrown Portal 1 Pack (or FOP1P, pronounced 'fop-ip') has you covered! This pack aims to resolve this problem by faithfully remixing all the texture set of Portal 1 in the Portal 2 Overgrown style. This pack features: 27 textures, composing of every possible variant for the Concrete, Metal and Plastic texture sets all lovingly damaged faithful to their looks - and more! Blend Materials for every possible floor variation! With both of Portal 2's dirt and moss blends being used! Every P1 Test Chamber Model retextured and adapted with a remake of P2's Craquelure texture, creating an authentic Valve-style look to the models. (Pellet Models and Turret not included) Credit is Required

Rusty BTS Props

This is a pack of assets that I recently made for Portal: Divinity Chapter 2 and have decided to also let the public enjoy. It features many of the iconic BTS props given a new rusty skin. Includes the pellet behind models, roommovers, gantries, cable beam, new colors and dirty skin for the bts lights, rusty conduit model, and has an extra gray colored conduit for good measure. NOTE: The chamber models use November's plastic. The material points to its original file location and you need November's overgrown plastic texture for it to work. If you want to use an alternative just edit the vmt to point elsewhere. NOTE 2: It might note fit extra lush environments because it's mostly intended for use in a sandy corroded environment, but it should still look a lot better than the clean assets in overgrown environments.
