---------

- Fixed shadow matte using the wrong background when display or brazil overrides are active.
- Fixed enabling the Sun or the RDK skylight adding the light to the scene when active lighting method is not "Scene Lighting".

-------------------

Features
--------

- Support Rhino Display Appearance "Backface settings".

- Shadow matte is applied to the groundplane if the assigned material is a basic material with 100% transparency and 0.0 ior.

Bug Fixes
------------------

- Fixed a bug that caused Neon material to update slowly when used as a child material.
- Fix Page objects being added to Neon scenes.
- Fix Block objects not being hidden when affected layers are hidden.
- Fix Materials not updating for block objects.
- Fix reference objects not appearing on the scene on startup.
- Adjusted the ways the Neon material polish and frost controls are interpreted. This will result in a reduced effect that should better match what the user expects.
- Neon no longer prints an error box in rare cases where an object was already in the scene, and the same object was being added again.
- Fix bitmap textures being read at a much slower speed than previous betas.
- Fix RDK Gradient procedural colors being swapped.

- Fix "Swap colors" on textures like Checker causing crashes.

Beta 7 2012.06.18
-------------------

Features
--------

- Added a new Command "NeonHUD" to toggle the visibility of the Neon status overlay.
- Added a new Command "NeonRenderControl" to allow pausing the rendering of Neon and locking Neon from restarting from updates.
- Neon will now automatically pause and resume while the user runs any of these commands: Render, RenderPreview, RenderInWindow, RenderWindow or ReduceMesh.
- Removed Neon HUD from ViewCaptureToFile/Clipboard captures.
- Fully support the different RDK procedural noise types.
- Support Brazil Plane primitive. Infinite plane is supported by creating a large finite plane.
- Support Rhino Display Appearance "Color & Material usage" settings.
- Support Rhino Display Appearance "Background" settings.
- Support Rhino Display Appearance "Flat Shading" setting.
- Support Rhino Display Appearance "Lighting Method" settings except "No Lighting".
- Support Rhino Display Appearance "Use lights on layers that are off" setting.

Bug Fixes
------------------

- Reduced the effect of bump to better match Brazil and Rhino rendererer.
- Neon no longer overwrites changes to the display mode settings
- Neon retains document settings such as max passes correctly.
- Fixed two-point perspective "missing function" error.
- Fixed Brazil Light domes and the RDK skylight using Y-up coordinate instead of Z-up.
- Raytraced (Neon) displaymode now defaults to "Use Renderer" as the background mode.

Notes
--------

- When a new update happens and Neon is paused, it will unpause and start rendering unless it is also locked.
- If Neon is locked, nothing the user does should cause a restart. All the updates are cached, ready to be processed when unlocked.
- If Neon is locked and the scene is modified, the wireframes will not match.
- Sparse convolution is really slow and does not work in the bump slots

Beta 6c. 2012.05.29
-------------------

Features
--------

- Speed improvement for models with many mesh quads
- Shader compile speed improvement.
- Support Brazil "force 2-sided" setting

Bug Fixes
------------------

-------------------

Features
--------

- Support Brazil Advanced Material: Velvet
- Support Brazil Utility Material
- Support Brazil Global Fog environment
- Added an overlay to the viewport which displays Neon status

Bug Fixes
------------------

- Initial world update when loading Neon is now properly run on the Render thread, resulting in shorter blocking times for Rhino
- Properly hook up Depth of field F-Stop control. This means that the Focus radius control now does nothing.
- Default light in Brazil no longer has shadow
- Enabled shadow bias controls for lights
- Fixed Adjustment being applied twice on bitmaps and HDRs. This fixes bugs like the opacity texture being inverted in Brazil Default Material
- Initial passes are shifted a few pixels - this is now fixed.
- 32-pixel repeating integrator pattern has been removed.
- Brazil Physical sky will no longer render a black sun if the sun is below horizon and Render sun is enabled
- Object to Object GI no longer bleeds through groundplane

Known Issues
---------

- Brazil Advanced Material: Velvet transparency does not match the Brazil transparency
- Global Fog does not fully match Brazil

Beta 4. 2012.05.03
-------------------

Features
--------

- Added pass throttling proof-of-concept code. Should improve Rhino rendering/boolean etc performance.
- Support Brazil Two and Three color gradient environments

Bug Fixes
---------

- Sun updates should now be realtime
- Fixed "Use sun colour" checkbox not working in Brazil Sun settings

Beta 3. 2012.04.27
-------------------

Features
--------

- Support Linear workflow (with latest Rhino 5.0 Beta)

- Fix updating a Brazil Advanced Material taking too long
- Enabled backface reflections for non fully transparent materials
- Fixed Basic material emission slot not working properly when reflected
- Fixed Brazil GI Environment having the wrong projection and ignoring the mapping of the texture
- Sped up adding and removing lights from the scene by a large factor
- Fix groundplane not emitting or receiving GI rays
- Fix groundplane "show underside" option not being hooked up

Known Issues
---------
- Brazil Physical sky colorscale is slightly off
- Brazil Physical sky will render a black sun if the sun is below horizon and Render sun is enabled
- There is now a hardcoded limit of 60 active lights in the scene
- Object to Object GI bleeds through groundplane


Beta 2. 2012.04.19
-------------------

Features
--------

- Support for Two-point perspective.
- Support Brazil Fresnel Blend as a texture in a child slot, IOR map is currently disabled.
- Disabled baking for sphere, planar and cylinder mappings, as per current Rhino behaviour.
- One processor core is now reserved for modeling.
- Initial Support for ViewCaptureToFile/Clip
Notes:
Same size capture works straight away.
Custom size capture needs to re-render the scene, blocking Rhino until it is done or the user cancels the process via hitting ESC.
Doing a custom size capture will cause the viewport to restart rendering after the capture is done.
High-resolution captures (capture dimensions larger than current screen dimensions) are not supported.

Bug Fixes
---------

- Fixed a rare bug that caused Neon to render with wrong featureset.
- Moved "Baking Texture..." trace to log instead of Rhino Console.
- Fixed a crash bug with several materials
- Auto-save caused a restart (along with several other events - saving a named view, cplane etc)
