Unable to import .vox file with multiple parts

[OkamiWong]

When I import the .vox file with multiple parts edited in the world editor of MagicaVoxel 0.99.4.2 as a static mesh, the result mesh is cracked;
When I import it as a destructible mesh, the unreal editor suspends.

Unreal Engine: 4.24.3
I used the proper build of the plugin.

This would be kind of an issue for me as well. I know the plugin still works and builds just fine for 4.25.1 so I'd love to see this supported if there's still interest in the contributors to keep plugging away at support.

Hi @OkamiWong, @datapawwolf

I trying support extension formats in support-vox-extension-format branch.
Please check it out and try to build plugin.

Build destructible mesh is heavy process.
Try it with small objects.

@mik14a Thanks for the update!
However, I had trouble building it in UE4.25.1. Here is the log:

Sorry @OkamiWong

It has been updated to use sub-modules for the vox reading process.

git submodule update --init

Need update the libVOX sub-module.
README will be updated later.

I'll give it a shot soon myself! I appreciate the updates to plugin. ^-^
