I'm super-excited to announce the release of AllSky Free for Unity 3D!

This is a free edition of AllSky! It contains 10 skies from the AllSky set for use in your Unity environments. Each sky is provided as 6-sided cubemaps sized from x1024 to x2048 per-side along with an equirectangular cubemap texture from 4k to 16k in size. Each has an example lighting setup scene! I hope you find these skies useful!

The full version has 200+ skies and is available here.
