Syntax
class FGlobalDynamicReadBuffer : public FRenderResource
Remarks
A system for dynamically allocating GPU memory for rendering. Note that this must derive from FRenderResource so that we can safely free the shader resource views for OpenGL and other platforms. If we wait until the module is shutdown, the renderer RHI will have already been destroyed and we can execute code on invalid data. By making ourself a render resource, we clean up immediately before the renderer dies.
