A simple solution for 'vanishing instruments'
« on: August 14, 2014, 04:59:30 pm »

Some of you may know about this, but I'll post it anyway.

I remember some people had trouble with the instruments on Basler Turbo BT-67, so they simply vanish while in Oculus Rift mode, and/or using higher FOV.
This problem may not be only present on that plane, but on any other 3D model containing small sub-objects.

The solution would be:

Open eng.cfg with any text editor you like, then change the next parameter:
   From: min_obj_size = 5.0,
   To: min_obj_size = 1.0,

From what I understand, this says: When Any object size on screen, is under 5 pixels, then it will be vanished/occluded.

For instance, the object size is taken from it's bounding box. So, I used to take a triangle, collapsing it (to not be able to be seen), and moving it few meters away in any direction. This way, I had a bigger bounding box/object which won't be occluded so easily.

I may be wrong with something, but this worked for me, so I hope it will work for you too :)

Apparently there's a bug in Oculus mode, culling by object size doesn't take the split screen and distortion into account, behaving just like the FOV was increased.
