[SZ_DXH]

Greetings to all of you, 
does anyone have a tutorial to port car mods from the b41 to the b42? 
I have tried it in many ways and I achieved this ;v im new

 

here is an example, cant get in or view the vehicle mechanics and my character is like no col with this, and for the truck yeap that group of whells same thing 

 

 

this is in b41 all working right

 

 

 

and this is my best result using  a b42 car mod as a base but the wheels are crazy, some times my character can pass trow like there is not coll but alleast i can drive it 

but surprise has coll and i can puch cars off the road, i want to bring some of my collest cars that i have,  if can some one can create a tutorial for porting i will apreciate so much

The wheels problem looks like an issue with Vehiclewheel shader in build 42. Please try revisiting the scripts where you define models and remove lines where you set this shader to models entirely. Like if you have a line "shader = vehiclewheel," - remove the whole line.

You also might want to fiddle around vehicle editor to get the shadow to match the shape of the car better or look where seat(door) areas are located.
