Adding functions such as Material Reset, Look At, and Physics Simplification Opt

[h1]Material Reset[/h1] After unchecking the "Enable Material Settings" option in the material panel, a reset button will appear. Clicking it will reset the material settings. [h1]Look At Camera[/h1] By checking the "Look At" option in the camera panel, the model will continuously face the camera.

This operation can be undone for the model on the "Model" - "Modify" page.
