Installation

The particle editor is disabled from the Workshop Tools by default

To enable the particle editor we have to edit these files:

steamapps\common\Counter-Strike Global Offensive\game\bin\sdkenginetools.txt

steamapps\common\Counter-Strike Global Offensive\game\bin\assettypes_common.txt

Search for particle and comment out like this

	//m_ExcludeFromMods = 
	//[
	//	"csgo",
	//]

	//m_HideForRetailMods =
	//[
	//	"csgo",
	//]

Save and now when you start the workshop tools you can select Particle Editor

warning

This has to be done every game update (I think), or at least once in a while
