Model Gap Fix — Guide

What It Fixes

You are most likely to notice the problem this mod solves when:

• Holding an item in first person and seeing a faint transparent line down its edge.
• Looking at dropped items or items in item frames from a shallow angle.
• Using higher render scales, GUI scales, or certain resource packs that make the seams stand out.

After installing the mod, those outline gaps are filled in and the item silhouette reads as one continuous solid shape.

How It Works

When the game bakes a 2D sprite into a 3D item model, it walks the outline of the opaque pixels and generates thin side faces around the shape. Model Gap Fix slightly lengthens each of these side strips along its own axis so that neighbouring strips overlap at the corners instead of leaving a sub-pixel gap.

The adjustment is tiny (a fraction of a pixel) and does not change an item's overall size, texture, or shape - it only closes the seams. Because it hooks the model-baking step, the fix is computed once when models load and has no per-frame cost.

Performance

The mod does its work during model baking (when resources load or reload), not every frame. Item models gain a couple of extra fractional-pixel quads at most, so memory and frame-time impact are negligible on modern hardware.

If you use very high-resolution texture packs and are extremely tight on video memory, the small increase in generated quads is the only thing to be aware of - in practice it is not noticeable.
