Knapping, clay forming and smithing textures question

[Torvosaure]

Hi!

I'm trying to make a theme pack and I have an issue, I want to make a 16x textures pack but the issue is that I don't know how to fix this when using 16x16 textures for metals (ingot) :

 

If I rescale them to 32x32 (without any interpolation) I'm getting this :

So.. anyone know how to make it work properly?

More like... how to make theme pack using 16x16 textures properly without the need to scale up (like grass top atlas, clay, ...) for some textures and fix texture position for crafting system like knapping, clayforming and else?

Are you saying your taking a 16x16 texture and stretching it to a 32x32 texture currently? And you want ti to be lossless when stretching the texture?

No, that's not what I'm saying. When I use the 16x16 texture, some of the clay forming/knapping, etc., uses part of another texture. What I want is a 16x16 texture that doesn't have this issue.

When I scale up (without stretching) to 32x32, the pixels is not perfectly aligned to the voxel, creating some parts cropped in the texture.

I can add the fact that upscale back to 32x32 create an issue for rock with breaking blocks overlays (make it 2 by 2 breaking animation).
