I've mentioned this before, and I still think it would be an incredibly useful tool. Moving the UV box with arrow keys would be a large time saver for small adjustments. I used it often in Cubik Pro.

The "particle" texture is used for when a block breaks, or is run across. It doesn't really apply to item models.

I tried that, but the syntax doesn't match up with the example PE entity file I have. I'm pretty sure it wouldn't work.

When I select "PE entity" in the model settings and attempt to export as a json file, it says I can only export blocks and items. I looked around the forums and couldn't find a fix for this. You said on the 16th that PE entities were on the todo list, so I assume it's an unfinished feature? I just ...

This is just a small addition, but something I used a good deal in Cubik Pro was the ability to move the face in the UV window with the arrow keys. It's super useful for, among other things, textures that are mirrored to the opposite side of an image. Instead of clicking and dragging, you can just ...

Bug: "Avoid bleeding edges by modifying UV mapping doesn't seem to work correctly."

Feature Request: "Seperate grid sizes for 3D workspace and UV mapping. I've found myself switching grid sizes a good deal when working with models larger than 1 block."

Added: "Hide/show elements applies to all existing elements, not just what you have selected"

There a bunch of little things that take more time to do in Studio than they did in Pro. One that comes to mind is having to click on each dropdown in the element texture assignment menu, whereas in pro, you could mouse over the menu and use your scroll wheel or arrow keys.

Another feature idea. It would be great if voxel spheres could be created with an intersection as the center, as opposed to a block. That way (especially when working with minecraft) you could create spheres with even number diameters.

What is the model you're using? You may have created it larger than the 3x3x3 block limit Minecraft has.
