Native plugin interface texture manipulation

Hi folks,

I'm trying to manipulate a D3D9 Texture in native code. I used the RenderingPluginExample42 as a reference. Everything works fine, as long as I assign the Texture to a Renderer Material just as in the example. As soon as I'm trying something slightly different (drawing it via GUI.DrawTexture in the OnGUI method or using it as a source texture for a Graphics.Blit) Unity crashes. I can't imagine I'm doing something terribly wrong in the plugin itself since the code is pretty much straightforward and I just replaced the code that fills the content of the texture.

Is there some basic limitation to manipulating textures in the UnityRenderEvent, which I'm not aware of?

Thanks a lot,
iko

AAAARGHH!! Guess what. I DID something terribly wrong. Just not comfortable outside of OpenGL, so I thought there must be some mysterious DirectX magic to this. Glad to see it's actually quite simple.
