Black squares issues

Hi all,im getting a strange issue...some black squares in the car.....
Anyone know what cause this issues?
Thanks in advance.

 

Update on this issue:
So far i think is related to the track and not the car,because i have removed the REFMAPO and the issue is gone.....
Also do not happen in Sebring by example,oficial track installed in devmod.
Some help is required mrs devs,for me dev mod as some bugs.....also some cameras setting as stoping working like shaking etc,only work if i put RF out of focus.
Please check this,because modding RF2 is starting to be a litle frustating whit all thoses issues.

 

Skip Barber,same issue....

 

Which track is it?
If it's a 3rd party mod track and the problem is related to it, you can not blame the devmode.

 

Looks like censorship to me. Some items have been redacted? Sorry couldn't resist a joke.I think @Bernd could be right though.

 

Is a track converted from RF1,but only now is strating showing this issue,is one of the firsts track for drifting that i have converted,i know that is a track issue,but the first version converted and released never have this issue,i tested to make shure and no problems in single player

 

Rofl...that was a good one actualy

 

Same track in single player,altough is the frist version,no issues.

 

Here i can agree.
Devmode and single-/multiplayer should work in the exact same way.

 

Update on this:solved the problem for now using the low setting for car reflections...strangers in the night......
