FOSS gamedev and creative worlds

I'm making a mod that adds kind of futuristic looking tools and a nice crafting system with it. But when I hold the tools some of the tool appears invisible on the edges where it makes a face side. Why is this?

Are the edges anti-aliased? If so, that's where your problems lies. Make sure the pixels on the edges of the png image are solid.

Redid all transparency but it still didnt work. Can I email my mod to you and have you see what the problem is?

You cannot add any translucent pixels to block/item textures, else the wielded item will have glitches.

I know that. I meant the transparency around the tool

I posted the mod, can you look at the textures for me gambit?
