ResourceGroupManager.InitializeAll AccessViolationEx[SOLVED]

Hello everybody

I just noticed a strange behavior and trying to investigate why it could be?

We kinda developed our own simple mogre framework taking the tutorial framework as an example so in the end it starts with this.


if (Mogre.Root.Singleton == null)
{
_RootRef = new Mogre.Root("Plugins.cfg", "ogre.cfg", "ogre.log");

SetupResourceLocations();

GraphicsRootInitialize();
//***********************************************************************************************************
Mogre.TextureManager.Singleton.DefaultNumMipmaps = 5;
Mogre.ResourceGroupManager.Singleton.InitialiseAllResourceGroups();
//***********************************************************************************************************
}
else
{
_RootRef = Mogre.Root.Singleton;

}

After this starting code we create the renderwindow's as our simulation goes multi window multi form(Usually having 3-4 renderwindows working. with two scenes.

The question is if I put the command Mogre.ResourceGroupManager.Singleton.InitialiseAll into the marked place. it gives a AVE(AccessViolationExp) but if I use it just after I create renderwindows and it works perfectly but gives the result of bad taste in GUI design empty renderwindows wait for our resources to be loaded. But main puzzling thing is I read through the manual and checked API reference and did not saw a thing about resource group manager needing the renderwindows (Not even viewport nor cameras are created at that time.)

It is not actually a problem but I wonder why this happens can anyone point me to right direction to study for understanding this.

By the way this is the log when it gives the exception.

IIRC, that's because Ogre queries the RenderSystem while parsing textures. But without a RenderWindow the RenderSystem hasn't been initialized --boom-> AVE.

it works perfectly but gives the result of bad taste in GUI design empty renderwindows wait for our resources to be loaded
To avoid that, you can do something like initializing a small bootstrap group first so you can show a loading screen.

without a RenderWindow the RenderSystem hasn't been initialized
Interesting fact, that I can't initialise the the whole resource system when I don't have a render window.
Good to know, because I thought about to fork my main application (sonar simulation) to work without any render render window.

Yeah we thought something like that too as our simulation is designed to be extended to be a CAVE simulation but currently works with 3 screens also in result reporting we use mogre too so I thought I should be able create the root and start the engine without the render target but it seems we will just go around it like smiley said. No problem actually just a simple redesign will be enough for us.
