Description

Blender Version
3.1 Release Candidate (March 7, 2022)

Short description of error
If using a curve that only has 3 points (ie. one corner) and Limit Radius is active, the corner radius will jump immediately from nothing to a full curve between the nearest point. Adding a 4th point (and beyond) to the curve reverts to expected behavior, except when additional point is in a straight line with 3rd point, which causes a different error at corner (see image; 3rd example).

Same behaviour in both Bezier and Poly modes.

Steps to Reproduce

  • Open .blend file
  • ☑ limit radius
  • Radius sets to it's max for curve with 3 control points

Yes, please always share an example .blend file (this just speeds up the process and makes sure we are all on the same page).

Behavior is same since Fillet curve node added in master- rB0d350e0193f1af82274ba78f5f93702c14646a86
Not sure if it's limitation. Will mark this report as confirmed for now
