Model only visible when {0, 0, 0} point of model is visible.

Hello,

I've (almost) successfully used proxies to create a (static wreck) model that is a copy of an existing BI model with extra memory points. I've got the proxy in LOD's 1 through to 6, ShadowVolume 0 and 10, Hit-points, view geometry and fire geometry.

I've manually created a Geometry (since the proxy's weights wouldn't go across), Memory and LandContact.

Everything works except when I look away from the model (in ARMA itself) the entire model disappears. It looks like the model is only shown when the center point (0, 0, 0) is in view.

Am I missing something? A call to boundingBox on it (in the editor) returns the expected values.

You didn't say but I suspect the model is large, or has points large distances apart within the model.

That being the case ........ very typical of the engine. I've seen this problem many time.

Hey Gnat, thanks for the reply, and thanks for your O2 tutorials, they were very helpful in getting started (particularly your LOD explanations). The object is quite small (+/- 3m on each axis).

It looks like ARMA figures out the visual bounding box (for deciding whether to draw the object at all) by looking at the points in each resolution LOD, ignoring any proxies. Since (for the resolution LOD's) all I had were proxies, it wasn't getting the right bounding box.

I solved it by putting in a few unconnected points around the edges (in each resolution LOD), which seem to have no visual effect but fix the disappearing problem perfectly.

Interesting find ...... thanks for the feedback Ian.

...... wonder if this can be used to our advantage on larger models .........
