Object disappearing\reappearing problem

[dmitri 0]

Have a large square foliage object. Displays fine, except when moving from the centre of the object to the edge. As I approach the edge, the object disappears, reappearing as I move further away. I have smaller objects with the same LOD\Geo setup that display fine.

Only happens from two of the four sides. Displays fine from all other distances. I've tried triangulating, reducing the size of the object, changing the class - no go.

Any ideas?

what lods do you have? and how many? can you recreate the problem in o2 viewer? usual suspects are a empty lod or a view geometry issue. maybe you have turned faces in one lod, would make sense that its only from 2 sides then. you said with smaller objects all is fine, how large is it?

O2 viewer is fine. My view geometry is empty (doesn't make a difference if it's occupied). Three detail lods. Normals are uniform.

It's just larger than the grid in O2, about 15 by 15 meters in ArmA.

I have cut the object down by 75% and now it's fine, so I guess it's size related. Seems the engine assumes the object isn't visible to the player once it's taking up a smaller space on screen and removes it. Something to do with the canocclude\canbeoccluded properties maybe? I've tried every which combination, no difference.

It's a criss cross network of planes, so I guess I can just recreate the original size using multiple objects in visitor. Trying to keep my object count down so that isn't ideal.

Objects in ArmA seem not to be drawn if they are outside of player FOV.

It seems that in case of some (if not all) objects it only checks if the center of the object is within FOV.

I am intrested how come that big objects such as aircraft carriers don't have this issue, maybe memory Lod points stop it from dissapearing?

Anyway, this is why I think OFP-style tree clusters could not work... (or could they? How is it solved with old imported Everon with pine trees forrests etc...)

Good luck with your work, the cluster looks nice.

They work just fine, VTE is full of them.

Does the Geometry work even if the objects have been placed via config (clutters) m8?
