Jordan's picoCAD Painter

Jordan's picoCAD Painter

This is a texturing tool for picoCAD models! Similar to tools like zbrush and substance painter, it lets you draw your textures straight onto your model! Unwrap your meshes in picoCAD and then load them in this tool in order to texture your models in a new, intuitive way.

This is a temporary itch.io page I'll hopefully improve it with later updated versions, I just wanted to get it out there!

Features:

- Draw directly onto your models!

- Full undo/redo stack!

- Draw onto the texture directly in a more traditional manner

- Both square and circle brushes with a customizable brush size

- Optionally limit your brush to the mesh triangle you started in (in order to stop yourself from going over the edges of a face!

- Limits your colors to the 16 picoCAD/pico8 palette so no need to worry about colors changing

- Save the models with your new textures

- Supports both save and save as (and correctly renames the filename in the file format!)

Instructions:

1) UV unwrap your model in picoCAD or the Unofficial picoCAD Toolkit.

2) Launch the painter and open your file!

3) Left click and drag to paint the current color, either on the mesh itself or in the texture window!

4) Move the camera with freecam controls. Hold down right click and pan to rotate the camera. Hold down right click and use wasdqe to move around the space. Hold right and scroll to change your movement speed. Hold shift to double your movement speed!

5) There are most of the normal keybindings (control+z, control+y, control+s, control+shift+s, control+q) along with a few unique ones (c opens the color palette, t opens the texture window)

6) Adjust the brush color, size, and shape in the top menu bar. Turn on or off the triangle limit to limit the brush to drawing in the same mesh triangle that it started in. (it uses triangulated mesh triangles not the original picoCAD faces because of a limitation of Unity, there may be multiple triangles per face but triangles will not cross between faces).

7) Save the modified picoCAD project file from the menu in the top left! The resulting file should work fine in picoCAD and every other tool!

This is the first release, there are a few known issues, but hopefully it'll be useful for you anyways! Issues that will likely be fixed in a future version:

- The undo/redo stack doesn't get reset when you open a new file (so if you undo items it'll go back to the other file's texture)

- While it does export correctly (and work when you bring it back to picoCAD), the alpha color is shown as visible when you draw it onto the model.

- Double sided faces are only shown as single sided faces

- No-Texture faces are still shown with a texture

- Often you'll have texture bleed on color borders (this may be unsolvable and on Unity's side).

- No way to change the background color at the moment

If you find a new issue please let me know and I'll try to fix it! (Or at least list it here)
