Model Gap Fix guide for All the Mods 10 0.32 to 0.50

Same as in the All the Mods 10 8.1 guide

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.

There are no machines, multiblocks or power systems here. Model Gap Fix is a simple client-side mod, so everything it does happens in your renderer while the game draws blocks and items. It targets a single long-standing Minecraft bug, the one that leaves thin see-through seams in block models and item models, and possibly other models that use the same functions.^[1]

Removing texture zooming

The core of the fix is that the mod removes texture zooming, so every model face uses 100% of its texture instead of the slightly shrunken slice it used before. That one change immediately cleans up the problematic gaps on models. The effect is most noticeable on items, but it applies to block models too, and it especially helps with custom block models and some 2D items.^[1]

The extra pass for 2D item models

Un-zooming the textures alone isn't quite enough for flat 2D item models. Those are generated quad by quad, and the base fix leaves behind another kind of very tiny gap that flickers as you move. So the mod also changes the item model generator itself.^[1]

• The generator never creates a quad that encompasses a transparent pixel.^[1]
• Instead it creates multiple quads, one for each row of solid pixels running in the same direction.^[1]
• Because the quads now stop at solid pixels, their side faces can be slightly enlarged without opening new gaps, which covers the remaining seams seamlessly.^[1]

Performance

You shouldn't see any performance cost. Removing texture zooming just removes some code and has no impact. The only nitpick is that the item model tweak can add a couple more quads for concave item textures compared to vanilla, which the author describes as negligible and only a possible concern when running high resolution resource packs.^[1]

What this means in the pack

Since the mod is purely client-side and works by patching the renderer, there is nothing to automate, no items to craft and no recipes in the modelfix namespace. It runs the moment the pack loads and applies to every model in the game, including the ones added by the other mods you're playing with.^[1]

Unverified The pack ships no config files for this mod, so there are no in-pack options to tune its behaviour, and no in-game toggle could be confirmed from the available sources.

This one is short, because there isn't much to configure. The project page describes Model Gap Fix as a simple client mod that fixes gaps in block models and item models by removing texture zooming, so every model face uses 100% of its texture. It lists no config options.^[1]

The fix is applied automatically. As far as the page describes, you don't need to turn anything on or tune anything for the gaps to disappear.^[1]

Unverified No config files for this mod are available for this pack, so I can't confirm whether it has any options or whether the pack changed any values from the mod defaults. Don't assume the pack has custom settings for it.

All the Mods 10 0.50 ships Model Gap Fix version 1.21-1.10 (file modelfix-1.21-1.10.jar). The mod has been in the pack since All the Mods 10 0.32 or earlier, so it is a long-standing part of the modlist.^[3]

The mod's own changelog for 1.21-1.10 has a single entry: it fixed an issue on NeoForge. No further detail is given there.^[4]

The pack changelogs have no entries for this mod, so there is nothing more to report about changes between pack releases.^[3]
