Old-School #pragma Messages to Yourself

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 "Fun" to be had (i.e. a big rant) in writing a general-purpose physical movement component (compound colliders representing static and skeletal meshes and more, but still interacting with the world as a physical entity). NOTE: All comments in this gist are by me.
// Comments are left by me, not from the code.
// Because why not have a default set or make the method abstract or, really, anything but this. Luckily no one would ever
// think to use ::GetMaxSpeed as a divisor or anything.
inline float UMovementComponent::GetMaxSpeed() const
{
return 0.f;
}
// FUN FACT: UMovementComponent defines a plethora of methods for managing the maximum speed of a component. It does not,

#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
