very nice. How would I animate the traffic cars? As far as I can tell these are just static...like this it would seem that even the potential for creating still images is limited to ones with a very high shutter speed where you don't notice that the cars are not moving because of motion blur.

Hi,

If you want to just add a bit of forward animation to simulate motion blur then this is possible but you must animate the source geometry (the car) and then convert it to a Proxy object. Here's the steps you'd follow to do this:

  • Convert the car model to a single mesh as in the original tutorial
  • Add an XForm modifier to the car.
  • Activate the XForm Modifier's Gizmo sub object level and animate the car moving forward. The distance and time will have an effect on the motion blurred results so it's worth experimenting.
  • Export the car to a proxy making sure that it stores the animated frames. The exact parameters are different depending on the renderer used.
  • Add the Proxy to your Forest object as normal
  • Go to Forest Pack's Animation rollout and turn on Follow Geometry
  • Turn on your renderer's motion blur and render


This was tested with the new Forest Pack 5.0 beta.

Obviously this won't allow you to create complex driving animations but for adding some simple motion blur it works fine.

I hope that helps, please let me know if you have any further questions.

Many thanks!

Thank you for the tutorial.  I had been using Civil View to place parked cars but the randomization options here are great.  It would be awesome if you could write a traffic plugin for animation.  The only options out there for us are not very well supported.  Your support and constant updates are among the best I've seen for 3ds Max plugins.

I am having difficulty with the color randomization.  At first it seemed to be working, but now I am getting all cars being one color.  I am using Mental Ray so I had to interpolate from the tutorial.  I am also using the Civil View cars which are aXYZ vehicles.  They have multiple sub-object slots that are used for color randomization.  Any ideas what I could have done wrong?

Hi,

Thanks for the kind words. Colour randomisation should work the same in Mental Ray as in V-Ray. Would you be able to send me a simplified scene of what you have so I can take a closer look? I'f you prefer not to post a link here, please send to support@itoosoft.com.

Many thanks!

I downloaded your Mental Ray files for the tutorial and duplicated your texture.  It seems to be working now.  Thanks.

Hi Paul. I was super excited to see the "official" parking tutorial with some clarifications that improved my own workflow quite a bit (I'm still trying to automate a bit more based on CAD parking lines that are already provided by the client so I don't have to do the added step of creating distribution lines...but your solution was pretty easy considering the old way of doing things). The random car paint colors using Forest map was great...took me a bit more time to tweak my library, but it's worth it.

Regarding the vehicle materials, I created a preset for a standard parking lot after I got everything working following your tutorial, but when I went to apply that preset to a new project, the car materials were all messed up (metal tires, non-transparent glass, way-off paint colors), so something obviously was getting mismatched between the individual car materials and the forest material. I checked the Material slot in the Geometry rollout and everything seemed to be assigned correctly, but I could click the assigned material and see there were two instances of each in the scene (one on the Forest001 object itself, and one on a hidden object on the forest_templates layer). When I clicked "Clear" above the Geometry>Material slot, everything magically went back to the way it should be and renders correctly. However, the Material slot for each object is empty.

I don't want to mess around with it much more since it seems to be working, but does this issue make any sense to you? It's one minor extra step to assign the Forest Pack preset and then select all the Geometry items and Clear their Material, but it seems like that shouldn't be needed. Is it possible I created my preset incorrectly? I can send example files if needed.

Thanks!
John

Hi Paul,
Thanks for your car park tutorial it has been really useful.
I was just experienting with using railclone to create the carpark road markings and Forest park for the Car and I wanted to use the same spline for both but I can not align them.
I have attached a max file , but it has seperate splines for  them.
I was wondering if you can tell me if i am doing anything wrong?

Thanks for your help
