I have been having some issues with a couple car mods, I don't see it replicated anywhere else and this may just be on my end. When I turn the lightbar on, either a piece of the model (one was a part of the wheels I think) will be enlarged and flash along with the lightbar or one of the textured planes for the orange strip of lights will be enlarged and flash. So far this happens with John11's Stanier for SAHP, where the side orange strips do that, and JMs FIB pack on another Stanier. If you guys have any ideas on how to fix this issue, I'd appreciate it! I haven't tried anything for these issues other than getting the enhanced lightbar system to see if that would fix it. It didn't.

As in; f.ex the front grill disappearing with the lights?

That's because they're marked as "extras". 
If you open the .xml for ELS of that car, you can see them marked as ELSenabled. 

Find out which extra it is (Using SimpleTrainer f.ex) and then set the isELSenabled to false. 

I don't think it's an issue with ELS. Die Probleme traten auf, bevor ich ELS installierte.

Can you show us exactly what happens then?

Sure thing give me a second.

@A Stranger here we are.

Looks like those cars require a carcols file.
Did the download come with one? 

not sure, but I'll check

 

Yes but it must be some values. I edited the 3 car's scripting now to see if that fixes that. Halved the scale of FIB stanier, fixed a rotation value on one of the orange stationary lights for the back of that LSIA traffic scout, and reinstalled the entire stanier. Testing it now to see the results. 

nope didn't work
