To [R-DEV]CTRifle:Thanks, i saw that tutorial,it was a long read, so i didn't got into the details,just read the short description of cols and lods.I'll read it in detail later as you suggested that i shouldn't worry about it now.
To rPoXoTauJIo:I don't know how to import a PR vehicle as i have tried and failed to do so,before.I never thought the cockpit is that detailed,never noticed it,i thought i was mostly textures.
----------------------------------
So please tell me how to make all models in the same scene , should i clone the jet and then make one as 1p and the other as 3p and then one more for the wreck? or should i make 2 different scene files for the 1p and 3p models?
Hierarchy, i don't know how to do that,but will learn soon.I basically just know how to move vertices and shape a model as of yet.

ops:
So bear with me, if i don't fully understand what you guys try to explain.
