I have a game I developed on Unity and since roughly a week (upgrade from Unity 2019.1 to 2019.2 ?), running my game on IOS crashes after few seconds with EXC_RESOURCE RESOURCE_TYPE_MEMORY (limit=1800 MB, unused=0x0)
I profiled my app, optimised textures but keep getting the issue. I am not really able to find where the issue could come from. Could someone let me know if memory values from Profiler below seem abnormal.
Thanks !
1GB of GPU memory used is very odd, especially you have 518 render textures that uses more than half a gig. Where are you using that many render textures? Did you release them properly? (Unity - Scripting API: RenderTexture.Release) Also, have you tried using memoryless RenderTexture?
As a background knowledge, GPU memory and CPU memory in iOS devices are shared, i.e. they are using same chunk of physical memory, so the resource limit counts both usages.
Thanks for your answer. I found out I was duplicating a lot of meshes and textures and cleaned them up. However the app is still crashing. Looking at the Simple memory analysis shows 1383 textures for 1.09 GB (I am sure I don’t have that many textures), but looking at the Detailed analysis, it shows me 211 textures for 227MB. Where could the difference come from ?
As my app is crashing at scene loading now, I can’t even play with textures. How can I dig in more into the real issue ?
Thanks a lot !
