Disappearing object!

[Guest]

I've been racking my brains to come up with a solution to this problem....and drawn a blank. I've tried everything I can think of to do with Geo, ViewGeo, FireGeo and Res LODs but thhe damm thing still doesn't work properly.

Problem is this:

Open the gate (animation works fine), run to the end of it and look around a bit and the gate disappears. This happens roughly when you can only see the last third of the model, and facing away from the original position of the gate. If the gate is closed (as it is by default) there are no problems. It only happens when the gate is fully, or just about fully open.

Now you see it:

Move my mouse half a cm to the left and now you don't:

MLOD format p3d in PBO HERE.

My first born to anyone who can give me a working solution!

Does this happens too, if you don't have alpha channels in your textures?

Haven't tried that, but it's an option I would really, really, really, like to avoid if possible. But I'll try it out....just got really sick of trying to make it work

Imho the wrong (or unfavorable) use of the lodnoshadow property may be the reason of this effect.

All Lods which are not use to cast shadow (beginning at the smalest resolution)

should be the lodnoshadow property.

All (resolution)Lods without this property can used by the engine to drop shadow,

in normal it's the smalest resolution without this property.

(to many points for the shadow could have a negative effect)

Add the "named property" canOcclude  1 to your geometry lod should fix your problem

Alt + P for the named property window

Also possible that you need to animate the selection in your view geometry or just take out the selection that may be blocking it

Tried both CanOcclude 1 and 0 and ViewGeo stuff with no success. I think the file I uploaded doesn't even have a ViewGeoLOD.....I got rather sick of trying to fix it.

The lowest ResLOD is the one making the shadow (1.000 in this case). I'll trying changing the shadow making LOD to one of the other ones and see if that helps.

Thx guys...I'll get back to you and see if anything helps.

Cannot confirm it, it's just guesswork but found a similiar effect when experimenting with matrices, especially with class forest, where it seemed to be close related to the aspect angle and matrix entries (especially scale and offset). So, perhaps it might not be a matter of LOD's. Maybe, perhaps clipped in one of the other display matrixes from DirectX. As said, just a guess.

[Guest]

Hmmm...if I can't fix I'm still going to use them. It's just not ideal obviously.

I had such a problem, as I tried to use proxies that are bigger than the model without the proxy.

Perhaps try something like this: Make a vertex or a small face that is invisible at the point/line where your gate will be when it is fully open. (in your normal resolution LODs)

If you don't have a "view geometry" then its using geometry as a "view geometry"

And if you animate the selection in geometry (how else are you stopping people from walking thru it?)

From my experiences you can't just name the selections the same as your animation in the view lods,it needs to be a new animation and synchronized with your view lod animation.From my experiences with folding wings on planes.

The way I have always done it (and I've never had a problem until now) is to let O2 name the GeoLOD components, then use the same names for the corresponding sections in all other LODs (ResLODs, View/FireGeoLODs). In fact this was the only way I could get a couple of very complex objects to work. Have a look at the pbo and you'll see how I've done it.

Congratulations! You will receive my first born by mail sometime soon (or whenever I get around to having kids)!

I put a couple of points where the gate ends it's animation and presto.....it doesn't disappear. Never ever come across this before, so thank you thank you thank you for the solution, and thanks to everyone else for the suggestions.

Yes great work ,coolbeans

Hehe,

looking forward to your first-born. Gonna hold it as a slave; it has to earn the money for a new PC and VBS1, then I'll give it back to you

[Guest]

Hehehe.....fair enough
