SkyMaxx Pro v5 - A revolutionary weather rendering engine for X-Plane 11!

X-Plane's most popular and best-selling add-on is back as version 5, and with some great new features!

Maxx-XP, in co-operation with Sundog Software, and X-Aviation are excited to bring you another game changing experience to the weather rendering in X-Plane 11! SkyMaxx Pro v5 is an X-Plane cloud and sky replacement engine boasting all-new technology for X-Plane that it's almost like having an all-new sim!

FSGRW Integration!: The FS Global Real Weather engine is able to process a wide variety of cloud identifiers, such as Cirrus, Cumulus, Stratus, Cumulonimbus and Towering Cumulus. Cirrocumulus, Nimbostratus and Stratocumulus depiction in X-Plane 11 is planned for the near future. This detailed, cloud specific information is passed onto Real Weather Connector, allowing SkyMaxx Pro v5 cloud types and their corresponding cloud textures in X-Plane 11 to be correctly interpreted and drawn for different altitude levels, while at the same time FS Global Real Weather injects real-time wind data into X-Plane 11. This adds a highly sophisticated level of realism to the X-Plane 11 world, and greatly enhances the immersive environment for both low-level GA flyers and high-altitude airline pilots.

How SkyMaxx Pro works
SkyMaxx Pro is a plug-in that disables X-Plane's cloud and weather rendering engine, then replaces it with the SkyMaxx Pro's version of clouds. It takes cloud data from the already existing X-Plane weather menu that you are used to, so there's nothing new to learn. What you gain are some amazing visual effects!

New features in Version 5:

GPU Ray-Casted Clouds
- Featuring the most complex, realistic lighting effects of any cumulus cloud layer offered (you will still have the option to run v4 style particle-based clouds).

Extended Draw Distance
- With the volumetric clouds we are able to offer extended cloud draw beyond that of v4. This allows for volumetric clouds to the horizon.

New Light Interaction
- Lighting and how it affects clouds is much more realistic with the volumetric clouds. Incredible scenes await you!

Load Optimization
- Techniques used to lessen the load between your GPU and CPU with proper distribution between the two for the volumetric clouds.

Integration with SoundMaxx
- Lightning effects in SkyMaxx Pro 5 will trigger 3D positional thunder sound effects when SoundMaxx is installed
