Vertical line of transparency running through the particles

[gopolygongo]

Hi, Not sure if this is a vfx graph problem or not but I am having an issue with transparency (see image) when my camera is at certain positions I get vertical line of transparency running through the particles, its not linked to the rotation of the camera just its position. Has anyone seen anything similar or have an idea what could be causing it, I’m now at the point where I am randomly turning things on and off with no effect so any help would be greatly appreciated,

Cheers M

Hi, I guess you probably have to make your particles face the camera position (Orient block in output)
