From a sketch on a grid to a game you can ship

The game-development tools are designed to hand work to each other. Level Editor maps import into Level Modeller as real meshes. FPS Lab loads both, baked lighting included. Everything also exports to the engine you already use.

Level Editor

Sketch the layout. Draw sectors in 2D, walk them in 3D. The fastest way from idea to playable space.

Up to now, putting a wall next to another wall in PapaiArt Tools – Level Modeller meant eyeballing it, squinting at the seam, and then typing coordinates into the Inspector until the gap went away. Your box landed at x…

FPS Lab 0.8.8 - New animation features

This update is all about the animation system. Three things, and each one removes a workaround you were probably already writing. The Play Animation node has a new Blend input: how long, in seconds, the object takes to…

PaTool LevelEditor 1.9 - EFPSE Export 2.0

Until now, exporting to EasyFPSEditor meant surrendering to its 64-unit cube grid: a diagonal wall came out as a staircase, and any floor height that wasn't a whole tile got rounded to one. That's over. Angled walls…
