How to properly cleanup RenderTargets

Hey all,

I'm having a problem with cleaning up my resources at shutdown. I'm using the DirectX 11 Rendersystem and when I shutdown my program I get these warnings from the DirectX Debuglayer:

Code: Select all

Now from what I can see in this log is that there are still some references to RenderTargetViews. In my system I'm using several RenderTextures and I'm suspecting that I don't clean those up properly at shutdown. What I do now in an attempt to cleanup those references is I call

Code: Select all

Ogre::RenderSystem::destroyRenderTarget

Besides that the only thing I call to cleanup is

Code: Select all

Ogre::Root::Shutdown

Now I thought that all the ResourceManagers in Ogre do cleanup themselves when Shutdown is called and properly release any used resources, but obviously I'm wrong.

Can anyone give me some direction in how to get rid of these DirectX warnings and how to properly cleanup resources after shutdown. If you need any more information about how I handle my resources in my program or anything else, please let me know!

Thanks!
