It sounds like you might be referring to a specific memory or rumor about Dungeondraft, the popular map-making software by Megasploot.
There is no official "1024 update" in the version history (the current version is around 1.0.4.x and beta 1.1.x). However, I think you’re likely recalling the "1.0.2.4 update" — a patch from the early stable release days.
Here’s the story behind that update, based on community memory from 2020–2021:
| Setting | Default (Old) | 1024 UPD (Tweaked) | | :--- | :--- | :--- | | Texture Atlas Size | 1024 | 2048 or 4096 | | Max Texture Memory | 512 MB | 2048 MB (2GB) | | Asset Thumbnail Cache | 256 px | 512 px | | Export Anti-Aliasing | Off / Low | Forced 4x |
In essence, the dungeondraft 1024 upd is a performance unlocker for high-end PCs. dungeondraft 1024 upd
defaults.json File%APPDATA%\Dungeondraft\~/Library/Application Support/Dungeondraft/~/.local/share/Dungeondraft/If you’ve been following the Dungeondraft patch notes or lurking in the Megasploot Discord, you’ve probably seen the buzz around the 1024 update.
No, it’s not a new sci-fi asset pack. It refers to a quiet but powerful shift in how the software handles custom assets and texture resolution. Whether you just updated your program or downloaded a pack labeled "1024 Ready," here is why that number matters for your next campaign.
A major component of this update revolves around the "upd" (upscaling) workflow. Prior to this, if a user wanted a larger map, they had to upscale the final exported JPEG in a separate photo editor, which often resulted in blurry artifacts.
With the 1024 update, Dungeondraft handles this natively. The software can now intelligently utilize "Ultra" quality texture packs released by the community. This means that the detail isn't just stretched; it is rendered. A wall that looked like a smear of grey pixels at 256 PPI now shows the grain of the stone and the cracks in the mortar at 1024 PPI.

Planning a physical session? A 1024-exported map scaled to 300 DPI prints beautifully on A3 or Tabloid paper. Lower-res assets turn into smudged blobs on paper—1024 keeps your props, blood spatters, and runes sharp.
There is no official button labeled “1024 upd” in the settings menu. Instead, the term refers to a manual configuration edit combined with a beta branch update that changes how Dungeondraft handles texture memory.
In late 2023 / early 2024, power users discovered that by modifying the defaults.json file and forcing the software into a 64-bit memory-aware state, you could change the atlas size from 1024 to 2048 or 4096.
The “UPD” stands for Update — specifically, the 1.0.3.2 beta patch and subsequent community tweaks that allowed for "texture_atlas_size" : 2048. Step 2: Locate the defaults
Verdict: 9/10 The 1024 update is not just a patch; it is a structural evolution. It solves the biggest limitation of the software—resolution caps—future-proofing Dungeondraft for 4K monitors and high-end Virtual Tabletops.
Open defaults.json with Notepad++ or VSCode (not plain Notepad). Look for the following line:
"texture_atlas_size": 1024,
Change it to:
"texture_atlas_size": 2048,
For extreme setups (RTX 3070+), use 4096. Do not exceed 4096 — the engine becomes unstable above 8K.
