I've spent hours on this and I simply cannot get it to work. 

I've set up some bugs crawling over a mesh following your youtube tutorial, doing the same. It works well in popcorn but in unity the particles are not in the right place. Yes, I'm using the projection childed under a localspace.

I've attached 4 videos. The first shows the effect with projection in popcorn. The second shows the same in unity. 
Then to show that the mesh is actually correct, I removed projection and turned off velocity. That way it still samples the spawnposition. As you can see, those tow videos Do match. So why doesn't projection?

I'm using popcorn 1.10.3.31081.

Hi Andreas,

Can you look in your PopcornFX editor project's settings, in the "Scene" section, the axis-system should be set to "Left-Hand, Y-up".

If it wasn't the case, you need to change it and possibly rebuild the mesh resources.

It is set to Axis_LeftHand_Y_Up
Hmm, then it might not be as obvious as I thought.  
Can you send us an email to support@popcornfx.com with the following info :
- Invoice number (from the email from the asset store)
- Unity version
- PopcornFX plugin version (found on the PKFxRenderingPlugin component)
- a package of the problematic fx (in the editor right-click->export to package)

We'll try to see what the problem might be.
Cheers,
...
