With the v36.00 release, we’re transitioning to the Left-Up-Forward (LUF) coordinate system. This replaces the previous Forward-Right-Up (FRU) setup from v35.00 and brings us in line with industry standards used by 3D tools like Autodesk® Maya® and Universal Scene Description (USD).
All transforms in UEFN—including those from Actors* and Verse—now use LUF coordinates. Rotations are expressed using Euler angles applied in LUF order, rather than Yaw/Pitch/Roll style.
What does this mean for your projects?
Your existing content won’t be broken or modified.
You will notice changes in how transform values appear in the editor for existing projects, including environments created with Scene Graph.
The update may require you to adjust your mental model when interpreting coordinate values and rotations.
Hey all! To prepare for v36.00 and LUF coordinates, you don’t need to make changes to your code or content for your published islands to function properly.
@Flak A possible typo in line 1935 of the Verse.digest.verse:
# * *yaw* is right-handed rotation about the Down axis,
ps. there are HEAPS of new efficient + useful calculations in this section now since v3600 - thanks so much!! <3
also cool: we can now extend rotation & vector2/3 with our own helper functions yeww!
