Models auto hide

[Gilmer]

Hello, im trying load the scene in c++, but im having the following problem. The models auto disappear. If i pass with the camera in a certain limit, all models, that are not vegetation, disappear. I was directly changing the file .sbx, and realized that when have few models, the problem is less, but if have lot models, the problem is greater.

 

 

My code is this:

Anyone had the same problem? i dont know what do.

You can try SetEntityViewRange(scene,3,1).

[Gilmer]

i cant, show this error:

 

error C3861: 'SetEntityViewRange': identifier not found

 

I do:

 

TEntity scene = LoadScene("abstract::pista1.sbx");
SetEntityViewRange(scene,3,1);

 

[Canardia]

It might be called SetEntityViewrange() or EntityViewRange().

Oh yeah, the Wiki says it's called EntityViewRange:

http://www.leadwerks.com/wiki/index.php?title=Entities#EntityViewRange

[Gilmer]

Another strange thing, that happens, is the FPS that drops, when i add some "road_node" in the map. For sample, in the map, have a lot "road_node", this influence on something? Because, look this:

 

With the road:

Without the road:

http://i54.tinypic.com/18hov9.jpg

 

very strange this..

[Canardia]

I think it's because the Lua script is doing calculations all the time. It could be fixed by having a global Lua variable like "nocalc=1", which would stop all all Lua scripts from doing anything.

[Gilmer]

hmm..i understand..

i will test this about the road scripr, because is making the lot diference in the FPS.

 

Now, about the camera, i test this command, it compile, but continue to dont work, the models hide in a certain distance from camera to some model, that i dont know what is.

 

Thanks lumooja

[AggrorJorn]

have you set any view distance options for them via their default lua script?

[Gilmer]

No Aggror, i see script by script, and none is be setting this.

 

I found this function in Wiki: SetWorldCullRange(), but ever time that i execute, resulted in "C Stack Overflow". I deleted the "atmosphere" entity from editor, to set this function in own code. My code is this now:

Just to you could see the difference:

 

The map in editor:

 

And the same map, with the same camera angle, in c++:

[ZioRed]

It really seems issue with view range, in your previous code you called (now commented):

 

EntityViewRange(scene,3,1);

 

But it is not intended to be used in that way, you should cycle through all the scene entities/children and call EntityViewRange for each of them and not just to the scene. But since you are using a SBX and calls LoadScene then I think it's easier if you set the view range to INFINITE directly from the editor interface for each object.

[AggrorJorn]

Also when an object has the default lua menu you can set its viewrange to either near, far or infite. Have you tried that?

Well, after thinking that all the objects in the scene loaded with LoadScene are children, I tried your code with "EntityViewRange(scene,3,1);" (whose third parameter is recursion) on a sample scene with a house on a terrain and it works, when I move far away from the house it is ever visible, so make sure you have the latest 2.4 engine/newton/shaders.pak

Thanks guys for the helps..

 

So, i saw script by script, and none has this function. I tried change in itself editor the view range, but the problem continue.

 

Uptdated all files, and try ever again, but same problem.

The strange is that ever models hidden when I'm in a certain position, until the models that on my side.
