Sidefx Solaris Houdini | Part 3.5 : Editing Layout LOP brushes
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.
Showing here two ways to manipulate these attributes. 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. I have a full course available on my gumroad called “How not to suck at Python“.
