Creating a Combat Knife Game Asset – Part 3 – Baking Normal Maps

Posted by Chris Plush on Jun 11, 2018

In the third part of this step-by-step game modeling series I’ll show you how to bake a normal map for the knife using Blender.

Whether you want to use this knife inside Blender or export it for a game engine like Unity or Unreal, I’ll show you how to make sure your model and its normal map look right in all other software. Check out the other parts of this series below:

Part 1 – High Poly Modeling in Blender
Part 2 – Low Poly and UV Unwrapping in Blender
Part 4 – Texturing in Substance Painter

I’ll also be showing you the steps for baking the normal map in 32-bit to avoid the color banding that the default 8-bit bakes produce. Then we’ll save the normal map as a 16-bit png file. This avoids color banding and gives you high quality normal map files. These files can then be converted to 8-bit in software like photoshop and instead of color banding the final result will have dithering instead, which looks much nicer than the banding.

Shout out to Aidy Burrows and Martin Turner for helping me sort out some info for this tutorial!
