====== Version 6.1 (Beta) ======
Release Notes

The biggest change for version 6.1 was the addition of deferred rendering support. That is, integrating SpeedTree into a deferred rendering system will be much easier with the new shader templates & asset compilation path.
----
===== General Notes =====

1.  Support for deferred rendering added. The Compiler application will export shaders for use with deferred rendering and the Reference Application runs with an example implementation.

  * CMultiRenderTargetsRI and CRenderTargetRI classes added to abstract platform render target systems.

2.  Improved internal profiling, particularly in the culling & LOD functions.

3.  Added ST_INLINE macro to issue more forceful inline directives.

4.  Added feature in CView::Set() help combat sudden leaf card over-the-pole flipping.

5.  Added more documentation about the shader system in general, including the new deferred features.


----
===== Bug Fixes and Performance ====

  * Several alternate coordinate system issues fixed.

  * Improved memory usage when dealing with large instance counts.

  * Eliminated depth-fighting in billboard geometry when wind is enabled.

  * Several PIX warnings removed for all DirectX builds.

  * All page titles in documentation now correct.

  * Wind effects would sometimes be lost in billboard shaders.

===== Reference Application Changes =====

1.  Overlay system added.

2.  Deferred rendering support added (as of the beta release, this was done for DX9/10/11, and PS3, with Xbox 360, PS Vita, and OpenGL remaining).

3.  SupportingData/ folder added in the Forests/ section. It contains files common to multiple forests, as well as misc shaders like the overlay and deferred lighting.

4.  Added FullscreenQuad.h/cpp, used in the deferred rendering system.

5.  SFC file changed:

  * "render" block replaced by "forward_render" and "deferred_render". Deferred render block includes directives for specifying lighting and other pass shaders.

  * Overlay support added.

  *Added surface_adhesion value for each grass type.
