Bristle brush issues when imported using Unity Toolkit/SDK
Using this brush in a project in unity causes the brush strokes to disappear the further away you get and you have to be very close to the piece for it to look as it should. Using icing or hull behind it helps but it is still not a proper representation of the artwork using that brush.

It's worth having a support post on this so I can track all the info in one place.
@cattasraafe Can you remind me what you said about it being OK if the sketch was exported in older versions of Open Brush?
I had been asking if a version difference might have an effect.
Say if a project started in tiltbrush and was finished in openbrush.
Would that project have any issues with current versions of unity or openbrush.
No idea at the moment.

Here's my result from an old sketch:

Changing alpha cutoff to zero does this:

(which is exactly what I would have expected it to do)
andy set mine to .08 and its seems to be a sweet spot
Is that different to the behaviour you're seeing? Is this the correct brush type? (Coarse Bristles)
I'm going to need more info. A quick test on a simple scene with 1 bristles stroke in it doesn't seem to have any problems but I might be doing something different to you @cattasraafe @zandyxr
Multiple brush strokes are the issue. Can send a screenshot before/after
A simple example scene would be best if you can
I cant right now Im super behind but this is .23
