Hi everyone, sorry if this is a silly question, but i cant find an answer on google and ive been fiddling for quite awhile!
Basically ive been modelling a bugatti veyron and the body is all done. I applied the symettry mod but there was still a gap so i increased the threshold value. This has sorted out the gap for the whole car except the hood where there is an extrusion that it dosent like. I cant increase the threshold anymore as it distorts other places of the car.
So i thought that I would delete/weld the vertices that are causing the hole but I cant edit the vertices for both sides because whenever I go into sub-object selection the modifier is turned off and I only have half a car. I can get vertices up with symmetry on but I cant edit them.
So how do I keep the symmetry on whilst editing the vertices? Thanks!
Here is a screenshot where you can see the hole on the hood of the car.
