Why it is invisible?

Why when i mod the car (make a skin or add new engine) the car disappear , and when a disable the mod and Ctrl+R , then appear again? Just...Why??

 

You are most likely missing a { or } at the start or end of the file. Or both. You could send the files here if you need more help.

 

here is the .jbeam file , which is just add a engine to sunburst...

 

You need another } at the end of the file

The last lines should look like this:

],
},
} <- this being the one you need to add

 

yeaaa! It finally work ! thank for ur help !
