Senior Material Artist at NVIDIA Stan Brown has recently shared the second collection of highly-detailed 4K 3D materials created for Portal With RTX, a ray-traced remaster of Valve's original 2007 Portal developed by NVIDIA Lightspeed Studios.
According to a new ArtStation post shared by Stan, he was responsible for bringing "Portal's classic materials to 4K PBR, trying to translate as much as possible from the original 512px texture files." The materials shown in the gallery were created from scratch using Substance 3D Designer. Attached below are some of the renders shared by the author, you can check out the full collection by clicking this link:
