Trail Renderer… a bit broken in this version anyone else noticed anything weird going on with it?
from the 5.5.0f3 project to 5.6b3 I’ve noticed the trail render in game view is doing some pretty things… ie the end trail seems to snap to random screen positions, however in the editor view it working fine and looks as it should… was working fine in 5.5 aswel.
It’s most likely from advantage if you can create a new project, isolate that issue and submit it using the bug-reporter along with an explanation how to reproduce the issue. That way, it’s in Unity’s bug-tracking pipeline and should get fixed eventually.
A few minutes after you submit the bug-report, you’ll receive a confirmation email. Unity often asks to put the Case number from that confirmation email here, so they can find your bug-report more easily if they look at this forum thread.
I think I’ve seen a bug reported that sounds like this issue… will be fixing it after Christmas 
I know… I checked a fresh scene in 5.6 to see it to see … and didn’t have the problem.
Anyway staying on 5.5 for now, I thought maybe moving the project to 5.6 would be fine but its these little things that always set me back and I need to make progress on the game.
I’ll check 5.6 again next year then, before 2017 is out 
5.6b4 its still happening
the trial is following mouse movement… it seems that this glitching only happens when the mouse position hasn’t changed position since last update, if the gameobject transform the trailrenderer is on is constantly changing position then the trail doesn’t show this weird glitching behavior.
as side note if you would like to make this bug into a feature of trailer renderer I have another use for it, it just needs to snap to another object in the scene instead of some random position I have no control over
The 5.5 trail renderer seems to glitch a bit on small movements and tight corners or movement reversals, spamming corner triangle fans to build the cornering. Also, sometimes it looks like the vertex data length changes and old vertices are being rendered when they either shouldn’t be or are dirty and need to be updated. I haven’t tested anything in 5.6 beta.
for me its totally fine in 5.5 … only in 5.6 is it going weird
You can track the progress of this bug here: Unity Issue Tracker - Regression from 5.6.0b2 : Trail Renderer is broken in 5.6.0b3
Hey, I can confirm that this issue is fixed in the upcoming 5.6.0b6 build.
ok great shame it won’t make it in to b5 but I guess its just another week
