Hey there,
@Rolo. Although not yet perfect, that's an interesting design you got there.
Here's some suggestions I have that might be useful:
> UV Wrapping: The texture looks weird on the base since the shape of the faces are trapezoid but it seems you mapped it to a square shape. The only other way i see this getting fixed is you alter the mesh a bit or alter the uv map.
> Billboard: In Magos' Model Editor, open up the Node Manager Window and then right click on the Bone that you attached the rune geosets to
(Ideally there should be one bone for each rune), then toggle the Billboarded option
(there are other options like Billboarded Lock X, Lock Y, etc.).
Hope it helps.
