Stop forest pack to penetrate walls!

(1/2) > >>

Morpheus:
If possible please to the future versions, to make forest pack
objects NOT to penetrate walls...

For example I create with 3ds max a house wall with solids.
As you see when I put outside the wall some plants, then
these plants enter inside the wall as you see in the picture...

It would be awesome when a forest pack plant "meet" an object,
then does not penetrate it but instead the object "trims" the forest
pack plant...

iToo:

You can fix this issue setting the Area->Boundary Checking to "Size". Then use the Geometry->Collision Radius to adjust the penetration distance. The value is adjustable for each entry of the Geometry list.

Morpheus:
Carlos I did what you said...
I have to "play" with a lot of values...
Anyway I hope it can be resolved
in more simply manner in the future...

I keep my values like I have them now and...
God save Photoshop!!! :)

Forest Pack is a genious piece of art plugin.
It makes the renderings flying...

So like every piece of art on this planet is handmade,
some things in Forest pack we have to "correct" them manually
outside the program, to archive the results we want....

iToo:
Unfortunately there is not a simple way to solve perfectly these kind of collisions. We use several methods to exclude the plants that are near the area boundary, but it is not possible to "slice" the plant. That should require some type of boolean operation, but (by several reasons) is not applicable here.

Anyway, the Area Boundary option should work fine here. In the attached image you can see the difference between using "Point" and "Size" mode. Using the default Geometry->Collision Radius (100%), the plants are excluded perfectly from the spline's bondary. You can adjust the penetration modifying this parameter.

Note: The Boundary Checking feature only is available with Areas of type Spline.

alexrecentspaces:
Is there a way or similar tool to Boundary for Surface as the distribution object? I tend to use Surfaces more often (almost all the time), as it's simpler to just grab the faces that I need and grow things on them. Drawing splines (or extracting them) is a lot more time-consuming.

I face this issue a lot, where grass will spill over the edges of a surface or trees penetrate inside walls. If we could simply use the outer "boundary" edges of a surface as a fixed boundary I think this would solve it.
