Mobile platform builds hang the engine upon Play if a material is using 3 textures

Bug number: 759846

I seem to be getting hangs when the platform is set to iOS or Android if a material has an Albedo, Normal (Height map too), Albedo x2 applied. It will crash Unity straight away.

Setting graphics emulation helps stop the hang in a simple scene but for my larger project it doesn't and I can submit that project/bug as its very large (over 10gb project). From what I can tell, it might be related to the above.

Anyone else getting this?

Happens in both 5.3.1p1 & 5.3.1p2.

 

You can always create a new empty project and just pull out a small subset of assets that prove the problem.

That give you two benefits.

1. it might reveal that the problem doesn't occur the way you thought it does

2. it gives you a small project that you can easily submit as a bug report.

 

Thanks Kurt for the reply.

I did create a small project and reported the bug with the small attachment and it would hang with the minimum number of steps mentioned above.

 

Well, at least that's a Good Thing(tm). I hope your bug gets looked into.

Meanwhile, if I were you I would keep experimenting with combinations of textures and material settings to see if it is in fact something else that is aggravating the condition. You might wanna go back to an earlier version of Unity (install side by side) and see if it also hangs.

 

I noticed a new 5.3.1p3 and gave it a go. Sadly this issue is still open and hope someone from Unity take notice. No one replied to my submitted bug either.
