High Poly to Unity / Taleweaver Ready - Part 2 Normal Maps
This is Part 2 of my series on breaking down a high poly mesh meant for 3D printing into a low poly mesh with textures that is appropriate for Unity / TaleSpire / TaleWeaver. This video takes things slow and offers a detailed explanation of the workflow. Mistakes are left in with explanations of how to correct them. It also takes the fast and loose approach to UV unwrap and texture painting. The 'correct' way using seam painting will be covered in another video for those interested. Also, if you don't want anything explained and want a rapid 'just the facts' version, that is coming soon as well.
This video covers: Prepping your mesh, converting it to a low poly mesh, creating a cage, creating the UV map, creating the normal map, and previewing the results in both Blender and TaleWeaver.
