This is a draft user page. It is a work in progress open to editing by anyone.
Remember to check for any notes left by the tagger at this article's talk page.

This page explains how to use existing normal maps to create detail textures that can be used to add more detail and simulate bumpmapping in GoldSrc GoldSrc's vanilla OpenGL renderer.

Icon-Important.pngImportant:This page assumes the existing textures are designed for traditional Source Source Engine-style rendering. If the textures are designed for PBR, they should be baked into traditional textures first. Only a $basetexture and $bumpmap will be used.
Warning.pngWarning:Only normal maps (DirectX or OpenGL) work with this method; ssbumps cannot be used!
