Bug DrawMeshNow() the electric boogaloo?

I have been trying to use Graphics.DrawMeshNow() and the render basically flash at random, I also happen to debug log the current camera, which also happen to alternate widely between null and main, and that seems to match the the flashing of teh mesh rendered by Drawmeshnow ... WHAT IS HAPPENING? is there is a fix, is it a bug? Why camera current becomes null?

 

I'm on built in, unity 2018, in editor (for now)

haven't tried on build yet because i didn't have mastery over the parameters yet (like correctly positioning mesh to stamp on the texture where i want).

I haven't tried over srp, or other unity versions, because I'm not sure what's the trade off yet about features, as im still doing experimental stuff, so i sticked to the devil i know. I'm doing a proof of concept before porting elsewhere.

 

I don't remember if I filed a bug report oups ... I think I did, but it's still there in 2020.3.23f1

I work around it by not doing render (DrawMeshNow) in update but in start ... which work in editor (stable, since the render only happen once), but nothing work in build I don't get it

 

Will do
