Hi, theoretically you probably can add one by one object (randomly A, B or C) if the rest length of curve is longer enough.

For the method there can be several approaches but you can also do everything in vex.
Sorry to not take time to elaborate a more precise solution.

Thank you! I understand it can be done in softimage and then transferred to Houdini? How is the transfer going?

Hello, this script “just” compute a fixed focal in function of your kind of camera (or with the sensor size if your camera is not referenced).
After, it's just a matter of UI menus to set and autofill 3d camera values parameters.

But you always need to position and orient your camera by hand (anyway, a right focal parameter help a lot !).
Then you can export camera with fbx.

Or just copy paste focal to houdini with a mathematical conversion (cf. this thread for conversion : interesting thread [www.sidefx.com]). And then position and orient inside houdini.

I hope I'm clear.
Cheers

Ok, it's too bad but thank you for your response.
