You can also orginize it

Maybe this can help

@Theoasterix you don't need glasses as windows. You can link glasses with lights as child... you do not need so many things. Keep materials, it will be all right.

@Theoasterix Well, maybe you can just reorganize it. Maybe not to call it "extralights" and "indicators", but "miscs". So far as lights ID are correct it will work. Indicators work fine with right ID even if they are miscs. Just don't crash without collision parts.

@Theoasterix Yes you should, for all parts. That is what I ment... "Reset all collison parts to parent".
That means all parts will have axes same place as bumper.

@Theoasterix yes, because round parts are set as glass to break, ID121 , and flags 3and4. That is why openIV shows it in diferent color. But try first what I wrote you earlier , make just simple grouped collision for bumper, make just two parts and and group it (you can split bumper collision in two parts and group it again), you want your bumper collision with shown corners around it... leave all other things for now. You just want bumper to be removed with everything in it for now. Later you can go for breakable parts if you like.

@NajPotez I also checked my mods to be sure, in carcols it should be enaugh just to turn off bumper_f bone.

@Theoasterix Yes.. that is normal, I think. You can maybe try to make just simple grouped collision for bumper, make just two parts and and group it and see what happens. Your glass will not crash, but (so far as I remember dealing with it) all parts inside your bumper should turn off with your bumper bone... I am so sorry - I want this to be solved almost same as you. I know it can be, because I did it with some of my mods. For your tuning bumper, also, try to change collision bone to chassis ( if it is not)... just don't give up yet:)

@Theoasterix It is hard to see what is wrong... Are all collision parts reset to parent?

@Theoasterix ...Ok, now try this: Click on last one, "extralight_2 [COL]", press and HOLD left Ctrl, and check all your "[COL]s" in there fom bottom up. Last one "bumper_f [COL]". All 4 parts should be highlited yellow. Now click on "Group" - you will have now just "bumper_f [COL]", but underilined.
Now...uncheck "L0", and everything but "COL". Convert "bumper_f [COL]" to Compound. If you did everything right you will notice some lines as corners around it. That should be it.

@Theoasterix You need something like this... I actually never published this version of thismod... I did not like that glass don't break on mod parts... but so it is even on original vanilla cars

@Theoasterix because it is not grouped. you have to make parts of it and group it.

@Theoasterix Linked (group) collision. I used it for Renault8, add-on version, and it worked. It was not bumper, but grill, but should work for bumper too.

This week
(adding some extras)

@GreenAid

OK, this should be it:
L1 = 65,7K polygons
L2 = 15,6K polygons
L3 = 557 polygons

Finishing, I hope to publish it till tomorrow.

@GreenAid Medium 170k, Low 66k, and, to be on the safe sade:), I even made LOD3
