P3Dv6 New Atmospherics Engine

The new Atmospherics Engine in P3Dv6 offers new volumetric clouds that replace the previous EA/trueSKY clouds when using the volumetric clouds as set with the P3Dv6 cloud quality option. Some features of ASP6 are not compatible when using volumetric clouds at this time. This includes: Cloud detection features, in-cloud motion effect, in-cloud visibility reduction, high-resolution radar/precipitation accuracy, and ASCA compatibility.

When using non-volumetric (legacy) clouds, all cloud-detection features and cloud structure/texture ASCA compatibility are available.

Frequently Asked Questions

Q: Can I have ASP3D and ASP6 both installed at the same time, so I can use either one?
A: Yes, ASP6 is a separate product and does not replace ASP3D. You can have both installed and use either one depending on which simulator platform/version is in use.
