Cockpit problem...

I'm trying to convert a rfactor 1 car to rF2.
Among the many difficulties I am encountering, there is that of the car body that is visible in the cockpit view.
Infact, i can see the roof and the pillars of the car body (which is less high) to penetrate the roof of the cockpit.
I tried to see how it's made the ISI Kodi (which also uses an old style cockpit).
Even in the Kodi, the body of the roof is more lower than the roof of the cockpit, but in incar view, the car body is not visible at all, I can see only the cockpit geometry!
I looked at the contents of the .gen files of the Kody to see if special measures had been taken, but I found none.
What is the trick?

 

There are sometimes different mesh that is seen just when in cockpit view, and those seen when viewing from external cameras. Their positions may differ. There may be no need to have both with the power of today's computers. I think everything under the "COCKPIT" heading in the gen files is what is seen from cockpit view.

 

Make sure the material isn't set to 2 sided

 

WCCARBODY?, nope, single side...

 

rF1 uses separate cockpit gmts doesn't it? rF2 doesn't have a separate one. So rF1 probably implies some exclusions that aren't apparent in the files.

 

ISI Kodi uses separate cockpit as in rF1



As you can see, the cockpit doesn't match the carbody, in cockpit view you should see even the two uprights (those of the cockpit and those of the carbody), in reality, as in Rf1, in rF2 the display is correct.
In my car on the other hand, I see both cockpits, that of carbody.gmt and that of cockpit.gmt.

Why?

 

What objects do you have in Instance=Body_in? One of then will be your issue for sure.

Is the car body interior a separate object or attached to the main body?

 

This is a common problem I've encountered with some rF1 conversions.

You'll need to split the interior from the exterior in the 'carbody' GMT. Create a separate GMT for the interior, and then mess with LODs to make it work. It's time consuming, and quite tricky, but it can be done with 3DSimEd.

You basically want the 'cockpit' GMT LOD at 0.00 to 5.00, then 'interior' GMT LOD at 5.00 upwards depending on if you have LODA, LODB etc.

ISI Kodi ZR is done in the rF1 way and works, mine not.
