# UnityNormalMapInverter Convert normal maps from DirectX (-y) to OpenGL (+y) "Sky in your Eye? Flip your Y" - doctorpangloss This is a simple tool for converting normal maps from DirectX style (-y) to OpenGL (+y). why are there 2 standards that contain the same information but have slightly different configuration? beats me. But ive seen too many people use the wrong type in the wrong engine, so I made this in-editor tool to fix it, which is much easier to use than opening gimp, decomposing the colors into the RGB components, inverting the G channel, recomposing, and overwriting. A render engine will use either DirectX or OpenGL style normals. Some common examples include: OpenGL: - Unity - Blender - Houdini - Maya - Zbrush - IClone DirectX: - UE4/5 - Godot - CryEngine - Source Engine - Substance Designer/painter How do I know if my normal maps are fucked? Cause they look like this:  HOW TO USE: 1) Open the NormalFixer Tool (Tools/NormalMapCorrecter)  2) Drag the normal map into the only slot on the tool. Then press Invert Normal Map. (it might take a while to convert the map, depending on the size)  3) Set the desired file destination + name. Click “save”
