Solved Trunk not working

wont appear ingame, trunk w/ spare tires
you can select the trunk in the trunk option, not under

 

Problem shows up clearly in the log. Spawn the part and check your log.

 

not sure what this means

 

It means that you declared a flexbody but didn't do anything with it.

Refer to the wiki: http://wiki.beamng.com/Introduction_to_Vehicle_Creation

In other words you should have a node group which matches the group name you declared in the flexbodies section. I'm not certain about coltris, but the coltri group name should probably match as well?

 

well, it looks fine, but i might juts be bad at this

 

...and what nodes are in that group? (compare with a stock part if needed!)

 

I think it's because I left it as is, if im correct it should match with the flexbodies
