Issue with Trail renderer in Unity 5.3.x

Hi,

I am trying to render trails in Unity 5.3.x and i get two issues:

1. In Forward rendering mode the Trail flickers constantly and most of the trails are invisible half of the time
2. In deferred some work as supposed, others dont appear and others work half way (sometimes appear, sometimes not)

The same scene in forwards rendering may show a flickering trail group and changing to deferred on the fly fixes it and looks great (in other scenes does not happen that well and both forward and deferred are not working ok)

This was not happening in previous versions (e.g. 5.1.1f1).

Any idea what it might be ?

Thanks

 

Some videos showing the system in deffered and one altermnating between forward

Trails in deffered mode (seem to work 100% in this sample, so i guess in deferred all my Trail based effects would run ok with tweaks):

Comparisson (shows problem in forward rendering):

Thanks a lot for the heads up.

Maybe i will have to re-create Unity's system from scratch to avoid the issue.

 

Cool - thanks, Richard
