This pack adds smooth transitions between versions of panorama(Beta 1.8 - 1.18 snapshots) with new vanilla shaders. Works without optifine.

It isn't compactable with other menu texturepacks.

In version 3.0+ you can add or remove custom panoramas. Just make it as was in original pack and it will work with any amount of panoramas.
Also you can configure transition speed and amount of cycles in <pack>/assets/minecraft/shaders/core/position_tex_color.fsh:
7 line: #define CHANGE_SPEED <speed:decimal>
8 line: #define TIMES <amount:integer>
Now it's easy to add future panoramas)).

You are allowed to make and share add-ons with your own collections of panoramas to pack. Just add me to the credits or make pack only with changed files, so my pack will be padding for your creation.
