What's New:

* Optimised mesh structure that allows better control of individual parts. Previously part control is done at material level meaning invisible parts are still taking up certain rendering resources.

* Major updates in physics. 99% of PMX models should work as expected now.  And the issue after changing model scale has been fixed.

* Fixed a few issues with PMX compatibility, more models can be used now.

* Improved detail texturing of skin and hair materials.

* Loading is done progressively with configurable phase in effects. No more freezing during load.

* Optional items support. XPS optional items are now supported and can be quickly accessed under the new optional items menu. For PMX models, previous sliders that controls body & clothing parts are now grouped under the optional items menu for easier access.

* Alternative textures. Some XPS models come with alternative textures, this is now supported under alternative texture menu. To allow the program to locate alternative textures, the files need to be located in subfolders of where mesh file is found and they should have the exact same file names as the default textures.

* Other bug fixes and improvements.

Breaking changes and known issues:

* Material settings are renamed to avoid issues with duplicate material names for some models. This means material config generated from older versions will not be recognized in 1.1. 

* Model config files are relocated to settings directory under your content library. Previously they were stored next to the model mesh file. This is to avoid triggering rescan of the content library after changing model settings. The program is still going to load config from the old location if config is not found at the new location but once the new config is generated it won't attempt to read the old config again. 

* The new optional items setting overrides material toggles. Certain material toggle state might now restore after reloading the model if they are also controlled by optional items.

* Facial expression animation seems not working, still investigating.
