Level Geometry Tools

Spline-based Houdini Engine tools


This is a set of level geometry HDAs I developed while working on a team project as a combination environment artist and technical artist. I worked with the level designers to see what kind of parameters they need, and with the artists to make sure the assets followed the style. In-engine tools like this are very useful for being able to edit the levels easily and allow designers to tweak levels themselves.

Wall Tool

This wall tool comes in both angled and curved walls, with a vent opening in the floor that can be repositioned.

Exposed parameters:

  • Wall height
  • Vent toggle
  • Vent position
  • Trim toggle

Railing Tool

A glowing railing to guide players and prevent falling off of certain platforms.

Exposed parameter:

  • Height

Stair Tool

Floating stairs that also follow a spline, allowing them to be curved or straight and angled at different grades.

Exposed parameter:

  • Step distance

Rafter Tool

Rafters were important navigation method for the player in the game, and worked well in combination with set dressing tools for floating platforms.

Exposed parameters:

  • Size X
  • Size Y
  • Wire radius

Floor Tool

Drawing the floor with a path worked in many areas of the level, but had to be baked out and merged after all the level design edits had been made.

Exposed parameters:

  • Floor width
  • Corner radius
