I would like to use Landscape splines to remove the trees above the roads. Unfortunately I can’t find the selector settings in GetSplineData node to achieve this. (also those actors/splines doesn’t have tags)
Is there any solution for that?

Hi,
I’m trying to do the same without success till now.
I’ve found that option : Filter by class / Landscape Spline Actor
maybe you’ll have more luck !

Thanks, I found this yesterday. Unfortunately I can’t get it work either.
A temporary hacking solution is to draw a spline along the road, and use it in PCG.
I have got an answer from AdrienLogut.
“I plan to talk about it in episode 4, but in the mean time, you can get your spline by tagging it, and then use “Get Spline Data”. It will work with Splines and Landscape Splines”
thanks. I was able to find a way to tag Landscape Spline (even worst, i cannot select the Landscape Spline itself, I can only the LandscapeSpline Control Point or Landscape segments : never the spline itself).
So looking forward for Episode 4 to see what i’m doing wrong !
In Selection Mode
you can select Landscape Spline Actor
and add an actor tag.
Then use Get Spline Data
with All World Actors and By Tag

thanks but i cannot see those. Is there something special to do ?
How i create my splines (in landscape mode)
In selection mode, i cannot see the spline:
No right click option to expand Landscape
In Landscape mode, i can only see control points & segments
EDIT: Adding the correct pictures
You’re still in Landscape Mode, switch to the default Selection Mode on the top left :
[EDIT] : I did some testing, I think this only works if you have World Partition enabled.

If you don’t want to use World Partition, just adding the tag to the Landscape Actor itself also works!

sorry for that - I didn’t add the correct pictures. I’ve edited my post.
My problem was that the i will never see the Landscape actors in selection mode. So
I think i understand why now. I created a copy of SimpleForest provided in the example for PCG. That level seems to have some settinigs preventing Landscape actors to show
When i use another level (eg Third Person default level), and recreate my landscape spline, i can see it.
This might be due to World Partition disabled on the SimpleForest example: i was not able to activate it nor check if it’s active…
The cool thing is that my code which was not working on the Simple Forest level works now 
Thanks for the hint about level partition !

Thank you for the explanation. It is bad that we can see the missing puzzles only with world partitions for the splines. Hopefully it will be fixed in the next version.

Push down the bottom of the volume below the surface.
If that doesn`t help, click on the PCG component and clear, regenerate.
P.S.: this is a totally different subject.
The solution is the GetSpline node, but the selector class type should be “Landscape”

I tried the tutorial on my project and I find the road spline is not able to exclude trees and other stuff. The difference is my landscape is created from the Openworld template. (world partition) Not Basic map . I tried my PCG Graph it works on Basic. Is this a know issue?
Its weird I changed tag name to Road I can get the debug sample now, but still can not generate any trees.
I found an easy solution for a spline based PCG Forest.
Here is the tutorial I created with the snippet to paste into the PCG Graph:
