Almost every shield resource pack I have found only serves to change the position, size or opacity of the shield, although there are others that do change the model, they are not usually compatible with banners, so I wanted to make my own version of the shield.

The only thing that bothers me about the vanilla shield is the plain texture when using banners, hiding the wood texture and the characteristic nails of the shield. I also wanted to change the shape and make it more interesting.**

Features:

The shield now is wider, more detailed texture with metal border, bigger wood planks, nails and a more medieval shape.
The tactical shape of the shield allows you to see clearly when it is in the left hand.
Fully compatible with banners, using the wood texture for the color map, all drawn manually, instead of a boring plain color.
Tweaked some patterns to match with Wavy Banners
Bigger scale in item frames to use the shield as decoration.
New unique texture on the back of the shield.

Note:

I recommend Wavy Banners for more consistency with the patterns.
If you want a more vanilla shield but still improved, you can use Better Vanilla Shields [Coming Soon].

Dependencies:

This requires <s>Optifine</s> or better yet Entity Model Features [EMF] + Entity Texture Features [ETF].

This resource pack is also available on Modrinth.
