After months of development I have finally created a 3D TPT mod! Does it lag? Nope. It works based off of the current engine, using layered particles to store 3D information, and a fancy ray tracing renderer that lets you rotate the scene and view creations in 3D!

The mod is still WIP, so some controls and UI elements are not complete yet.

Download:

All platforms (Download)

Features:

- Rotatable 3D view, layering based 3D renderer

- 3D pressure, ambient heat and gravity maps (additional z layers "estimate" values from a base layer)

- 3D SPRK, heat conduction

- 3D brushes, such as cubes, pyramids, spheres, etc...

- Additional 3D quick options (see README.txt)

- Random extra tools I added for fun, such as dynamic transform tool (scale and rotate, in 3D!), better prop tool and configurator.

- (WIP) 3D moving solids and fluids (3DSD, 3DFL)

- (WIP) Other cool "rejected" TPT stuff like magnets and planets

Controls:

Use arrow keys on the side to pan within a layer or rotate, use Ctrl-O and Ctrl-I to move between z-layers. You can draw on only 1 z-layer at a time (unless using a 3D brush, in which case it's centered on the z-layer). Rotating the camera still restricts you to the xy plane, the z-layer rotates with the camera.

You can use buttons on the top left to quickly change camera view to front, back, top, etc...

Todo / Known bugs

- The particle limit's still the same, so your 3D creations are limited in size

- SPRK sometimes causes infinite loops when conducting between 3D sheets

- Pressure approximation is unrealistic

- Better indicator for current z-layer (maybe draw the plane or a grid?)
