Trail Render with Orth Camera possible?

Hi
I'm creating a "2D" sprite based game and wondered if it's possible to have a trail render on objects? I tried using a perspective camera, and it worked well. But switch to orth camera (that I need for pixel accuracy), and nothing appears. Am I missing something?

Thanks

 

I've just tried a trail render with 3.1 in a simple test situation and it seems to work fine. Try switching to the scene view while the game is playing (and the trailed object is moving) and see if the trail appears when you zoom in close.

 

OMG You're right --- why didn't I see this before? *Stupid late nights*!
