00:00:01 Introduction
00:01:30 Create Digital Asset and bring it into Unreal
00:03:38 Auto-Assign Unreal-Material
00:05:20 Bring Houdini-Material and Texture into Unreal
00:11:35 Bake Texture from Houdini-Output directly in Unreal

Note: If you bake a flow map, this map needs to set "flip green channel" in unreal.

This video explains the basic workflow of bringing a cube as Houdini Digital Asset into Unreal and making use of Materials (both, already existing Unreal-Materials or create a new Material/Texture coming from Houdini). Also, we'll setup a Houdini-Bake-Node which we'll trigger from Unreal to update our bake results after we modified our digital asset in Unreal.

The Maps Baker HDA allows you to very quickly bake texture maps through either custom attributes, texture reprojection, or generation. Provide the tool a low-poly mesh, and a high-poly mesh and bake from one to the other. This tool is a lightweight baking solution similar to the other solutions, but instead fully written in COPs using VEX. It is EXTREMELY fast.
