Official API for Neighbor-Aware Block Rendering(Connected Textures Support)

Hello Minecraft Bedrock team,

I’d like to suggest an official and performance-safe way to support neighbor-aware block rendering in Bedrock Edition.

Currently, resource packs and addons cannot change block textures based on adjacent blocks. This makes it impossible to implement real connected textures (like glass, paths, stone variants, etc.) without heavy block replacement hacks that cause lag, flickering, and instability.

I understand Bedrock’s rendering pipeline (RenderDragon) is optimized and sandboxed for performance and cross-platform support. Because of that, I’m not asking for full shader or engine access.

Instead, I’d like to propose a limited, official API, for example:

• Exposing simple neighbor flags to the renderer (north/south/east/west/up/down)

• Allowing block texture variants to be selected based on those flags

• Keeping all logic engine-side to preserve performance

This would:

• Greatly improve visual quality

• Reduce the need for unstable script-based block swapping

• Empower addon creators without breaking Bedrock’s design philosophy

Java Edition already benefits from connected textures through mods, and providing a native, controlled solution in Bedrock would be a huge step forward for creators and builders alike.

Thank you for your time and for continuing to expand Bedrock’s creator tools.
