Isengard tower graphics bug

[Helliaca]

Several users have reported the isengard tower messing up their screen when zooming in on it.

So far I have failed to replicate this issue.

UPDATE:

One of the people this bug happens to has given us the following info:

• They use a Mac M1 GPU
• This is what it looks like if you zoom out too far:
  
• This is at half zoom:
  
• This is when you draw a battle-plan:
  
• The regular ambient object models AND unit mdoels do not appear AT ALL:
  
• Changing graphics settings has no effect.

Deductions:

• The first picture shows Mt. Doom with the pink color, which implies that our custom pdxmesh shader is not being used. Either way, it does not seem to be a shader-problem in the first place, as we ONLY change the fragment shader.
• Our Barad-dur and Mt. Doom ambient objects have no scale defined, could this be the problem? Idk, as all three images above appear to show Orthanc, which DOES have a scale defined.
• Unit models also not being shown, implies that there is some issue with our models in general when used on Mac M1's.

Next step:

One possible fix would be to normalize the scale of the models to (1,1,1). This should be easy enough for the ambient objects, but not so much for the unit models.

I will go ahead with this and see if the problems persist.

Another option:
Try and set the scale of the ambient objects to 1 and see if we get similar images to those sent to us.

We should avoid adding more custom models until this issue is resolved.

Another idea: Try changing the renderers in the launcher settings (opengl, directx...)

UPDATE: This may or may not have been fixed as of here

Marking this as fixed, if it comes up again I'll bring it back
