func_instance
func_instance
is a internal point entity available in all Source games. It inserts an instance of another VMF file into the current one. You can translate and rotate the instance without breaking anything or creating an off-grid editing nightmare. By default, instances are drawn in Hammer with an orange tint, though this can be disabled in Instancing > View Instances
.

Input through an instance
- Define a Fix Up Name.
- Define a value for the input or output you want to use (if there is one).
- Send an input to the targetname "fixupname-value", e.g. MyInstance-Start. Hammer's UI won't recognise the name, but don't worry.
