1.3.1

Version 1.3.1 is a hotfix release that resolves a crash issue caused by missing default physic material.

Fixes

#399 Disable physics material tag by default.

#366 Supported assigning physics materials for 'EDIT' mode.
#205 Improved the Add Physics Materials window with features such as random color, enhanced naming settings, and automatic addition of the physics tag upon creation.
#371 Added a physics tag to physics materials, which can be used as a filter in the physics materials list in addition to naming.
#395 Updated presets to include the improvements made to the physics materials system.

UI/UX

#228 Transferred the settings for the Auto Convex operator into a popup window.
#225 Added a warning about the potentially slow operation of the 'Auto Convex' function.

#377 Fixed a crash related to the Convert to Collider function.
#311 Removed the console warning regarding the Operator naming of the physics material list.
#360 Corrected the display of Oriented BBox, which was previously shown as wireframe instead of using the default shading mode.

1.2.3

This release fixes a major bug regarding the creation of presets. It also introduces the setting to keep the original mesh materials for "Add Mesh" and "Convert to Mesh". This new setting is currently limited to the 'OBJECT' mode.

Features
