5.) You will get lifetime updates
II. Shader usage:
v1.1.2 (May 2020): Major new release. Blender 2.82 compatibility + some fixes + full Eevee support added
1. Corrected typos on the shaders
2. re-arranged the nodes so they will be approximately in the middle when you first open the file (they were mis-aligned and off-screen after first opening in previous versions).
3. Full Eevee support is here! The shaders were completely re-worked for Eevee and now they have transparency depending on the angle you look at the water (like in real life and Cycles). The main node works with Eevee now, no graphical glitches visible anymore, but it is still quite slow so a GTX 1050 Ti is a minimum requirement. The "Water performance" nodes work perfectly and are still recommended for Eevee. Since Eevee version is made differently some nodes don't have the same settings as the Cycles version, but they don't need them. The Eevee and Cycles variations are in different .blend files now.
v1.0.1 (February 2020): Initial release, the description is for this one. Additional information and new features description will be added to new updates.
