When changing texture size, other vanilla armors are affected

[turtle1230]

just took the FancyPants-Master texture pack and upscaled the armor textures by a factor of 2 to create 32x32 Minecraft textures.
I changed the TEX_RES in the .vsh file to 32.
As you can see in the image, other armors Netherite (Gold, Iron, etc., also tested) are negatively affected.

Minecraft 1.21.3 FancyPants-Master 32x32 / upscaled

Download for the upscaled texture pack.
Let me know if you need any further information.

With kind regards,
Turtle
