MC Toolkit

Overview

MC Toolkit is an Aseprite extension for Minecraft texture creators. It offers tools to create, edit, and export pixel art textures. Basically, it's a collection of random tools that i've made for myself.

Compatible only with version 1.3-rc1 and higher.

Features

It's highly recommended to have a backup of your working file before using this extension, because not every feature works really well at this moment.

Hue Shift - Hue variants generation

Creates up to 8 color variants from a single texture with configurable hue shift angles (5°-180°). Features advanced color correction including saturation, brightness, and contrast adjustments, plus an accent color system with customizable strength and color temperature controls.

3D Block Render - Interactive block preview

Provides real-time 3D visualization of your textures with mouse rotation and scroll wheel scaling. Includes auto-rotation with adjustable speed, customizable background colors, and automatic updates when selection changes.

This tool is highy inspired by Block Preview extension, but i wanted it to work for a selection, not for a whole sprite.

Render Adjacent - Tiling verification

Displays your texture in a 3×3 grid pattern to verify seamless tiling. Offers scalable preview with 1x-8x zoom, grid and background customization, and export options to new sprite or clipboard.

Intermediate Colors - Smoothing with nice preview

Applies one of 5 processing algorithms (edge_smoothing, bilinear, anti_aliasing, selective_smooth, smart_dither) to smooth textures. Includes intensity control, color sensitivity threshold adjustment, brightness and contrast controls, and palette reduction options.

Export Selection - Quick export

Provides quick export functionality for 16×16 selections using Aseprite's native export dialog accessible directly from the MC Toolkit submenu.
