Okay, here's how the new model previewer will look. I'm restructuring it to be more dynamic, easier to use and to be able to have more room for new file types when they need an editor.
There will be a graph of the right side popout menu with a row for each bone and its checkbox and a column for every frame. The graph will have a vertical and horizontal scrollbar and the popout will be resizable. The animation list will be moved to the left popout, where the bone list was.
There will be a keyframe point at the column and row for the bone and frame the keyframe modifies and clicking the point to send its data to the editor.
The CHR0, SRT0, VIS0, PAT0, etc controls will dynamically show and hide on the bottom popout when you select an animation from the animation list, if the animation has the file type attached to it. There will be a new tangent editor and an interpolation graph that you can edit for CHR0s, SRT0s and SHP0s.
The new layout will probably need a lot of getting-used-to, but it's definitely going to be much better.
Have you labeled the materials1 values, or whatever you're calling them? Do we know what they all do now?
Yeah, pretty much everything in the materials is known, except for the lighting section.
Shaders, which used to be materials2, is completely figured out.
