Title: Lot of cars placement on curvy surface
Post by: Bormax on 2016-09-01, 19:30:52

Hi guys,

Almost in every project which needs exterior views I have to place a lot of cars on streets and parking lots. Problem is that here, where I live and work, is not any flat pieces of ground. Always roads are laying on curved ground surface. It is really long time annoying job to place tens of cars on a roads rotating each of them by all axis in order to put all 4 wheels to the road surface. Normally I use proxies for car's bodies and leave only front wheels as a real geometry to have possibility to turn them if it is needed.
Can you suggest some fast way how to make cars aligned to the ground surface? Please, share your way how to place lot of cars on curved surface fast, if you succeed with this.

Thanks in advanced!

Forest or corona scatter would work.

Select and place if you have max2015+, some script that does the same job from scriptspot, otherwise.

For stills with a handful of cars, I place them manually in the top view to put them in the right spot and rotate to point in the right direction.  Then I use Itoo's Glue plugin to drop them all to the surface.  Your pivot point for the car&tire must be at the lowest point of the tires, and it works better if your tires are linked to your car.  But otherwise it works pretty well.  Alex mentioned Forest Pack... here's their tutorial on how to do that:  http://www.itoosoft.com/tutorials/tutorial_parking_cars.php

Hi. You can use CivilView to do that. CivilView has been in 3dsMaxDesign for several years, and is now also part of 3dsMax (since v2016). It places your cars along splines at put them "down" on any surface chosen.

It takes a little learning, but then it's really fast to use. You can even build a library of your own cars (or other objects).

Hope it helps

/in Soulburn scripts Collection exist perfect placement tool /Object Painter/ for random placement lot of random object's on curved surfaces///Faster and convenient than 3dmax /Select and place/

1 step/ Add collection of cars  and surfaces in /Obect Painter/ and turn off /random rotation/position/scale/ option in script menu . Rotate all collection of selected cars manually, following the direction that you need
on the road or the parking lot and ...  paint ///
2 step/ Select all cars and place them with Glue plugin on curved surface///

Note: It is important to Pivot Point position of the car, exactly in the center and bottom of Bounding Box of the car///

I do it almost every day in different projects, very useful :)///
Good luck///
