Starting shape (mesh) can be any of 7 primitives. Extrusions allowed and encouraged. May delete faces but models must remain connected.

What is picoCAD?

"picoCAD is a program to build and texture lowpoly 3D models. Where many programs for modelling and texturing are bloated and overly complicated, picoCAD aims to make it fun, easy, and accessible by focusing on the bare essentials. It is built on the PICO-8 platform and comes rich with constraints. Experiment to find your own workflow and anything is possible!" -Johan, creator of picoCAD

How to submit?

Please submit an animated Gif spin of your model, the model txt, and if you have it, the texture png. Example.

To create a spin, navigate to top left drop down menu and click "Export Gif". Select either fast or medium spin.

To copy the model txt, click view files in top left menu and copy it from the folder.

For learning how to create an page read Your First Page.


  1. Models are required to incorporate the theme. Limitation is an optional modifier.
  2. Make your model within the jam timeframe
    • You may sketch concepts before the Jam starts but do not use assets made before the jam.
  3. Make only one submission.
    • You may work as a team and submit a group-made model.
  4. Use only picoCAD to make your model and submit animated Gif spin of it.
    • Do not use external modelers/editors for editing model or gif submission, including editing the model txt files. Pixel-art editors for textures are the exception.
  5. No harassment of any kind. No NSFW content, offensive content, excessive gore/violence.
  6. Entries that violate rules will receive a warning and be removed before voting if changes aren't made. 
    • You will be asked to submit a new model or edit to make your model valid. Models made before the jam started cannot be submitted.
  7. Have fun!


Models will be voted based on following criteria:

  • Visual- aesthetic enjoyment from the model
  • Technical- high quality modelling and/or texturing
  • Concept- creative take on the theme/limitation and/or novel use of picoCAD's capabilities

Voting will be open to submitters only. Submit if you are able to so you can participate in voting!



Be sure to read the manual included with picoCAD!

Waporwave and I have also written a supplementary guide for picoCAD. Included is a beginner tutorial, overview of modeling and texturing, and a FAQ section answering common questions and showcasing tricks like inverted normal or spheres!
