This additional part is very much a hack on how to edit the brushes of Layout LOP to bend them to your will... It's a much more technical video than usual but taking the time to explain how Orient attributes and Quaternions works to control the rotation of our assets.

First by using AttributeVOP (visual coding similar to UnrealEngine) or VEX scripting (Based on C language) 00:00 - Introduction 00:30 - What we want to fix 01:35 - Making brushes editable 03:51 - Fixing Scale 06:06 - Checking Orientation based on Normal 08:37 - Breakdown of align_to_normal 09:31 - What is a Quaternion ?? 10:40 - Fix paintbrush with AttributeVop 22:23 - Fix paintbrush with VEX 28:25 - Outro If you interested in learning more about scripting, especialy Python scripting.
