How to load a lot of resources without Error #3691?

NeronBurningRome

At the beginning of my game I'm loading Textures from BitmapData taken from .swf files. I'm trying to load 800 pictures like this and the Error #3691 comes up at 699th picture. Is there a way to load more without this error? Or do I have to limit number of pictures to max 700?
Also question - will this number be different on different computer with different graphic card?

May want to check out this thread, it looks like it has a solution if you're using AIR 50 or 51 and if this is related to Starling/Context3D:

Thanks.
I'm still using 30.0. Right now I don't have time to upgrade this. But it seems that this limit is coded into the software and is unrelated to user's graphic card. So if I limit number of pictures to 600 and it loads on my computer without error, then it should also load on other computers with weaker graphic card.

Adding the error description as context. Error 3691's description is: Resource limit for this resource type exceeded.

So it sounds like you have created too many textures. Stage 3D has a hard limit on the total memory available textures (There is also a maximum number of textures you can create, but according to the documentation it's 4096, which is much higher than 700). You cannot increase any of the Stage 3D resource limits with any AIR version from Adobe. It is a strict limit.

However, AIR 50 from Harman added an ignoreResourceLimits property to Context3D that should allow you to load more texture data into memory.

Sory for missing the description, I thought it's a common error.
In this game I have few more textures above the 700, but it's just a few. No way I have 4096 textures all together. So I don't know where my error is coming from if I didn't reach the limit. Their size probably matters too. Few textures are 2000x2000, most of them are around 500x500 though. I think there was stage3D property indicating the amount of memory used by textures?

Yes, I believe that there are memory size (in bytes) limits too. I recall some folks trying to convince Adobe to increase the limits so that they could take advantage of higher memory available to newer GPUs.

The Context3D documentation lists various limits, including on texture memory size. I may be reading it wrong, but some of it seems to be conflicting a bit. Regardless, it should give you a ballpark of the texture memory size limits.

You could potentially hit that limit if you load and unload textures from time to time (navigating between views, level changes, etc.), but you forget to dispose some of them, resulting in a memory leak. I suspect that you are hitting the texture memory size limit, though.

Context3D has a totalGPUMemory property, but it includes all resources, not just textures. However, I believe that textures will typically be the largest portion of that memory.

I tried to read totalGPUMemory but got an error saying it's null.
My situation was not about lack of disposing, because the error appeared at the beginning of the game on initial load.
Nevertheless I limited nr of pictures to 600 so I don't get the error anymore. And as I understand it this is a software limitation so it's unconnected with user's hardware, so people playing on different computers (it's desktop air) won't have that problem.
Thanks for help.
