In this 2,000+ word deep dive, we will dissect exactly what “1024 upd” refers to, how it relates to texture memory and export resolution, why the default 1024x1024 texture atlas cap is choking your high-definition maps, and—most importantly—how to apply the “unofficial update” to force Dungeondraft to use higher-resolution assets (up to 2048 or 4096) without crashing. To understand the “upd” (update) part, we must first understand the “1024.”
"texture_atlas_size": 1024, Change it to: dungeondraft 1024 upd
The fix is not a magical download. It is a deliberate, five-minute configuration change that re-architects the software’s core texture pipeline. By changing two numbers in a JSON file and opting into the beta branch, you transform Dungeondraft from a low-res sketchpad into a professional-grade battlemap studio. In this 2,000+ word deep dive, we will
The short answer:
Dungeondraft, developed by Megasploot, uses a system. Think of a texture atlas as a giant grid-sheet where all the individual pixels of your terrain brushes, object textures, and material patterns are packed together. When you paint a forest floor, the software doesn’t load 50 individual tree textures; it loads one master sheet. By changing two numbers in a JSON file
