After OptiFine starts supporting the pot model, it will look like this as a block

This resource pack changes the texture of the brush, framed pot and suspicious sand to those that were shown in Minecraft Live in 2020.

Obvious problems:

Pot in vanilla minecraft cannot change its model to the one that was presented to us on Minecraft Live, or at least I do not know how to do it. So its old texture before the release of OptiFine can only be seen in the frame

The item in the suspicious sand cannot be stay at one point, it leaves the block, and does not stand in its center, as we were shown on Minecraft Live

At the presentation in 2020, we were shown two types of brushes, at this time it is possible to implement this either through a mod or by renaming the item. Which is impossible while snapshots are coming out
