Hi there.
I really want to upload or create my own car's for the Sims 3. I don't know what software I need and what kind of converting program I need. If anyone can let me know what I need for creating car's, it would be much appreciated for myself and anyone else looking to do the same thing.

Thank you

Start here Vehicles, How? by BloomsBase.

I tried it last year, and got incredibly lost/frustrated. Of course, I neglected to follow the suggestion of trying to make a simple/non vehicle, first. Maybe I'll try it again someday, since TS4 still has a a ways to go for the type of game I like to play.

Thank you so much

Glad to help. FYI - to work with most of the models I could find out there, I also had to pick up:L

Zmodler3
Blender
And Forza Studio

Even with all that and a good source of 3D models, I lacked the patience to get everything imported. I hope you have better luck than I do – if so, do a tutorial! :D

Thank you again Yea hopefully they help out and sure, if I get the hang ill try and do a tutorial!
