P3D v4 How to use round earth correction right?

[Itay Dor]

Im exporting my new GP and when i go to P3D i see its flickering and not all textures shown. How i make it like all the big developers are doing it right?

 

[Itay Dor]

I got this but i dont know which tool to use on the newer versions. altho my GP is on 0 in blender

Hi,

You can enable the option to filter out the non-ground polygons, that will get rid of that message. You can also see then which polygons are removed, those are not ground polygons.

For the flickering and such, are you sure you layered the textures in the right order?

 

[Itay Dor]

all of the model it self flickers duo to ground

 

[arno]

And you have the ground flattened at the same altitude you use in the GPW?

 

[Itay Dor]

Yes. Should i make in ADE or with a BGL file or that doesn't matter?

 

[arno]

It doesn't matter, as long as you have a flatten for the airport. And be sure that in the GPW you need to enter the altitude in meters. not feet.

 

[Itay Dor]

still there is a message

 

[Itay Dor]

and dont think about lbpd_conc_edge i removed the texture

 

[arno]

It seems you have enter an altitude of zero meters in the GPW, while the airport seems to be around 600 meter altitude if I Google for this.

 

[Itay Dor]

Isnt it AGL automatically? and btw there is no object now
I figured i have to close the GPW to show the object

 

[arno]

No, in the GPW you need to enter the absolute altitude always, else the curvation can not be calculated correctly.

 

[Itay Dor]

So first i make a GP using GPW.
second i get this model in and apply correction?

 

[arno]

No, the GPW will automatically add the curve correction based on the FS version you select. That's why you need to enter the correct altitude in the wizard.

 

[Itay Dor]

oh and should i check "Optimize refrence point location"?

 

[arno]

It will give you better performance, but it is up to you if you want to enable it.

 

[Itay Dor]

it lifts my whole polygon up so i guess nope

 

[Itay Dor]

also is there a way to make a GP without GPW?

 

[arno]

it lifts my whole polygon up so i guess nope

That would only happen if the reference point location is not inside the flatten of your airport. The optimize reference point option puts the reference point in the middle of your object.

also is there a way to make a GP without GPW?

Yes and no. Of course you can do all settings in your modelling tool as well. The tricky part is the earth curve that you need to get the position truly accurate, I'm not aware of other tools that do that.
