The Ol' #pragma Message

For particularly necessary to-do reminders, the JM_TODO macro below will print to the build console (and on the warning/error list) as a trivial warning -- so it won't interfere with builds that treat warnings as errrors. Then you can just double-click it and jump to that spot.

The Code

#define JM_PRAGMA_STRING2(x) #x
#define JM_PRAGMA_STRING(x) JM_PRAGMA_STRING2(x)

#Quixel Megascans Scripting Reference ###Updated: Aug 19th, 2016

The Megascans Bridge allows the user to send assets from the Bridge to external applications. The Bridge currently supports the following tools:

3DS Max
Marmoset Toolbag 2
Unity 3d
Unreal Engine 4

#Quixel Megascans Bridge API ####Updated: Aug 19th, 2016

We have developed an API to fetch information from the Bridge. The following is an initial list of endpoints any software will be able to retrieve information from.

Megascans repository path
Zip folder paths
Get all assets (folder and json path)
Get selected assets (folder and json path)
Search results (folder and json path) against a string

	// noise point sequences"

	// Comments are left by me, not from the code.
