The only difference between local and http assets is that mesh, skeleton
and texture assets will be loaded asynchronously, meaning we pass the file
path to our asset cache for the file to Ogre and let its background worker
(separate thread) load the asset and inform us once its done.
I think the threaded way might be more prone to crash when you are close to
running out of memory. You can disable this threaded loading completely
with startup parameter --no_async_asset_load as you can see here
https://github.com/realXtend/naali/blob/tundra2/src/Core/OgreRenderingModule/TextureAsset.cpp#L73
local:// refs are never loaded with the thread as their disk source can be
from anywhere. And we would need to add every local storage path and
recursively all of its sub folders into ogre as a asset location. At the
time of implementing this I saw this not to be important and it would make
messy code. We could inspect if ogre knows to search sub dirs in locations,
meaning that we would only need to pass the root for all local storages and
then use threaded loading with the disk source filename. It would be nice
to get the loading path exactly the same for all storage assets, so we
could detect bugs like you have here (local not crashing, same web assets
crashing).
Anyway, profiler is your friend! View -> Profiler or 'prof' in console.
This thing will tell you everything you need and more. Ogre tab shows
totals of used memory. Textures can sort you the biggest memory spenders so
you know what textures you should optimize. Prefer making your textures
.dds DXT1 when you dont need alpha and DXT3 if you need alpha. There are
plugins to photoshop and others to convert other formats to dds. Microsoft
DirextX SDK gives you texconv.exe command line tool and Ludocraft has
written this
https://github.com/realXtend/naali/tree/tundra2/tools/TextureTool it is
located in tundra source repo /tools/TextureTool just go there and build
it. Seems like once its done you can use this
https://github.com/realXtend/naali/blob/tundra2/tools/TextureTool/ConvertAll.cmd
read
instructions there.
