Paving falloff scale & position
« on: February 22, 2021, 11:52:34 AM »
We're trying to figure out how to make a pavement like the roche-campus: https://landezine-award.com/roche-campus-kaiseraugst/

We have a circle area excluded which allows to change the size of the empty zone, while getting the scale effect with scale fall-off option.
But there are two things we still would like to do:
- is it possible to move the objects also away from that zone, so they look a bit pushed open like the reference?
- the scaling also affects the height, but for tiles it would work best if it scales only in x/y not z, is that possible too?

If you could give some advice or an example file for a best workflow that would be great, (also keeping in mind that grass would be placed in the empty zones)

Thanks in advance.

Best regards,
Vincent

Hi. Thanks for the challenge. We got to work, and Paul came up with the best solution first.


This method uses combination of techniques.

First we use Forest Pack with exclude areas, but additionally add two effects- One for scale, and one for repulsion:

These are controllable with curve, and numeric entries. This might be enough for what You wanted.


But Paul went one step forward. Here is technique, how to achieve more organic shape, as in Your reference:


There are few modifiers on top of forest object that does the job.

And for the grass You create new grass object and add tiles object as exclude area. You will have to play to get acceptable parameters, but ForestPack does the job pretty well.


Attached scene for Your reference.
Hope this helps. If You got any questions- ask.
