Include Particule to a landscape

Hello,

I’m testing and trying to include particules to a landscape which is a city street.

I did wall to make directions changes to my particules.

I set background picture to Front and then my ground modelisation is not flat. Particules are going going down because of gravity.

Do you know which set I should give to my backgound image to create 3d mesh with a flat ground? Is it a good method to create a particule animation?
My goal is to throw object on a city with big building. I get a picture of the city, I was thinking created invisible 3d mesh to create particules interactions. Then export animation to After effect.

Here is my working file.

Thanks you for your help

Have a good day, Rémi,

You have to construct your scene so that ground is flat. There is a Camera calibration addon BLAM for that or you could start by aligning grid and default plane by eye so that they align with a street surface and perspective looks more or less correct. This might soon get ugly though: http://www.pasteall.org/pic/show.php?id=102607
Your file does not have image packed btw, File, External Data, Pack.

Edit: (and double post for some reason) Image you model needs to be set as a Movie Clip and Camera Clip unchecked. If you check Lock Camera to View image stays visible and you can adjust scene position.

Hello thanks you for your answer, I’ll try BLAM, it’s look very useful. It’s working well by aligning the grid to my ground picture.

What the difference betwwen use MovieClip instead of Image in the background image? I didn’t saw difference.

Your street rendering is awesome :eek:

Thanks you for your help,

Rémi

If this is ‘background image’ it’s tied to orthographic views; as soon as you move Camera image is not visible. MovieClip option makes image always visible for a view through Camera. Kind of hard to explain more precise for me…
Btw, you have to set Render size equal to your image dimensions, one more important thing.

Hello, thanks you, I tested Blam add-in, it’s working well.
