Resource Pack will change a lot of things in Minecraft. Let's see what Better Plus can boast.

Blocks

Let's start with the fact that this resource pack will make your world smoother. Now the vegetation blocks have a larger grass layer.

The water now looks more transparent, and the water lilies on it have become more beautiful.

Wooden things now have a darker oak-like texture.

The logs have a certain roundness, and the birch has a spring color. I think spring lovers will enjoy walking through the birch forests.

Mobs

Don't you like creepers? Interesting fact: creepers are considered something like a plant. So now it will be harder for you to see them because they have acquired a darker color to disguise themselves as the environment.

I was the only one who didn't understand why iron golems lost a pumpkin on their head when spawning? Well, it's time to fix it!

Now the drowned wear the clothes they used to wear when they were zombies.

The blazes have suffered minor changes regarding the animation.

Weapons

Player's inventory has been changed. Now icons of armor is blocky. 

Pumpkin blur is now colored.

The wooden and stone tools began to look less strong. And the helmets have a similar texture as when the player wears them. 

Shield has wood-like texture. 

Elytras now based on smooth membranes. It looks so beautiful. 

Items

Many items have been changed. Most have acquired logic, others beauty.

Other

New Sun and Moon texture. 

New chat bounce animation(Thanks to Chainsketch)

Removed the circle on mobile devices.

Java door sounds. 

Please, don't redact my resource pack and don't use something in your projects.
