Animation invisible from up close

[Elektrohund]

I made an attempt to add an additional attack animation to the Blade Master model in MdlVis. It works in-game but if the camera moves too close to the unit the whole unit becomes invisible while the animation is playing. Putting the camera distance to 1300 in the World editor preview window replicates the issue.
Do anyone have any idea what could be causing this?

Have you tried recalculating the model's extents with Magos' Model Editor (Edit > Calculate Extents)?

That seems to have solved it. Thanks!
