I tried CTRL+E with the new 3D editor without success.
The only place where I found options to save in png/bmp/tga/dds is the Save in API mode but this just saves the Atlas texture of the particle effect.
Is there a way to save a picture of every frame of the particle system or an atlas of all those?
Basically replicate the icon for the emitters, but just making it animated in an image file.
