Model Gap Fix in All the Mods 10

Model Gap Fix is a small client-side mod that fixes a long-standing Mojang bug, MC-73186. That bug shows up as thin gaps in block models and item models, and possibly in other models too.^[1]

The fix is simple. The mod removes texture zooming, so every model face uses 100% of its texture instead of a slightly zoomed-in part of it.^[1]

Who it's for

Everyone who plays the pack benefits, and you don't have to do anything. The gaps were most noticeable on custom block models and on some 2D items, and the mod cleans those up automatically.^[1]

What it does for 2D items

Removing zoom alone creates another kind of tiny, flickering gap in 2D item models, because they are generated quad by quad. To cover those, the mod changes the item model generator. It never makes a quad that covers a transparent pixel, and it builds multiple quads for each row of solid pixels instead. That lets it slightly enlarge the side quads without opening new gaps. According to the mod's page, this extra step only applies on Forge, because Fabric doesn't get those tiny lines.^[1]

Will it hurt performance?

No. Removing texture zooming just removes some code and has no real impact. The item model tweak can add a couple more quads for concave item textures compared to vanilla. The author calls that negligible, and says it could only matter with high-resolution resource packs.^[1]

In this pack

The pack ships Model Gap Fix version 1.21-1.10 as the file modelfix-1.21-1.10.jar. It was already included in earlier releases of the pack.^[2]

Unverified The sources don't show any recipes, quests, configs or progression role for this mod, so there is nothing to unlock or craft. It is a background fix rather than part of the pack's progression.

Good news: there's nothing to craft to get started with Model Gap Fix. It's a simple client-side mod that fixes the Mojang bug MC-73186, which causes gaps in block models and item models. It works on its own, so you don't need to set anything up.^[1]

What it does for you

The mod removes texture zooming, so every model face uses 100% of its texture. That closes the gaps on items, where they're most noticeable, and on block models too. The gaps were especially visible on custom block models and some 2D items, which is handy in a pack with lots of modded content.^[1]

For 2D item models, the mod also changes how the item model generator builds its quads. It no longer creates a quad that covers a transparent pixel, and instead makes multiple quads for each row of solid pixels. That covers the tiny flickering gaps that removing texture zooming alone would leave. The source says this last part only applies on Forge.^[1]

What to do first

1. Load into the world as usual. The fix applies to rendering automatically, so there's no item to make or quest to start.^[1]
2. Look closely at a 2D item or a custom block model. Any seams or gaps that vanilla rendering would show should no longer appear.^[1]

Unverified The sources I have don't confirm any items, recipes, quests or config options for this mod in this pack, so there are no recipes to show here. If you see something different in game, treat it as unconfirmed.

Model Gap Fix doesn't add machines, multiblocks, power, fluids or item handling, so there is no automation to set up. It's a simple client mod that fixes a rendering bug where gaps show up in block models and item models, and it may affect other models too. The gaps are most noticeable on items, and also on custom block models and some 2D items.^[1]

How the fix works

The base fix is removing texture zooming. With it gone, every model face uses 100% of its texture, which immediately closes the gaps on models. It also covers block models and anything else that uses those same functions.^[1]

2D item models need one more step. They are generated quad by quad, and removing texture zooming alone leaves very tiny gaps that flicker. To fix that, the mod changes the item model generator so it never creates a quad covering a transparent pixel. Instead it creates multiple quads for each row of solid pixels in the same direction. That lets the mod slightly enlarge the side quads without opening new gaps, so everything is covered seamlessly.^[1]

Performance

The mod shouldn't slow your game down. Removing texture zooming just removes some code and has no impact. The item model tweak can add a couple more quads for concave item textures compared to vanilla, so it could be very slightly worse in that one case. The project page calls this negligible and says it would only matter with high-resolution packs.^[1]

What you'll find in the pack

There's nothing to craft, power or configure for this mod. The only source for it is its project page, which describes a purely visual fix.^[1]

Unverified The sources don't say which mod loader this pack runs, so it's unverified whether the extra item-model quad step applies here. They also don't confirm any items, recipes, config options or quests for this mod in the pack.

There isn't much version history to tell for Model Gap Fix, and that's normal for a small fix mod. All the Mods 10 8.1 ships version 1.21-1.10 of the mod, and it has been in the pack since All the Mods 10 0.32 or earlier.^[2]

The mod's own changelog for 1.21-1.10 has a single entry: it fixed an issue on NeoForge. The changelog doesn't say what the issue was.^[3]

Unverified Whether the pack's own release changelogs mention Model Gap Fix is not shown by the sources here, so no pack-specific changes are listed.
