Paid Plugins + Scripts Model(GLTF) Viewer

This update fixes skinned models whose animations would not play, models disappearing after loading, and incorrect foliage transparency.

What's fixed:

1. Skinned animation playback: rigged glb models now play their animations correctly. Enable "Load as Skinned Mesh" before loading the model. Otherwise the model loads as a static mesh and animations won't drive it.

2. New "Material Alpha Mode" option: choose how materials handle transparency: glTF Default, Opaque, Cutout, or Blend. Changes apply immediately without reloading the model, and the setting is saved in presets.

3. Foliage alpha fix: glTF marks leaf materials as opaque by default, which ignored the texture's alpha channel. You can now enable transparency with the option above.

Known limitations:

- Fully opaque textures (such as Pine brance x02 in pine_tree_1) show no cutout effect. This comes from the texture itself.

- With "Keep Transparent Materials" turned off, all materials are converted and transparency may be lost.

This update mainly fixes bugs that have not been solved before, so that the loader can basically achieve the same parsing ability as blender:

1. When loading a model with a high number of vertices, it is easy to have problems of vertex stretching and surface breaking.
2. Some models are distorted when loading (the reason is that some models, such as glb transformed by fbx2gltf tool, have no normalized weights).

1. The support for skinned animation has been greatly improved this time. Skinned animation is fully supported. Now there will be no more problems when loading animation and playing.
2. Optimize the hierarchical display/hiding logic of the model. Now only the level with actual Renderer will join "Select Node", which avoids the problem that too many options in the old version interfere with selection.

some new features supporting feedback have been added:

1. Added mirror switch. This function is added because the gltf model may have different coordinate systems. So you can decide whether to mirror the model according to the actual situation when the model is loaded.

2. Now, for the model with multiple nodes, it is convenient to control the hiding and displaying of each node. And can be saved to the scene.

Please see the video demonstration for details.

brought a number of core functions and bug fixes:

1. Loading. glb is now supported.

2. Add multiple preview modes (wireframe, no lighting, universal coloring).

3. Support scaling of models (some models are not suitable when imported).

4. You can now choose to automatically add appropriate collisions to the model when importing.

At the same time, the problem that the loaded model will be reversed along the X axis is fixed.

A number of other improvements.

Please see the introduction video for details.
