Instancing Forest Object
« on: August 18, 2020, 06:48:01 PM »
I'm trying to create a repeating environment. Se attached Image. Every tile should be repeated so that the same forest cluster repeats itself on every tile.
I know this is a bit of an unorthodox way of using forest pack since the main purpose is to create variation, but I want to create a loopable animation.

I tried to just instance the forest object but everytime it updates it loses it translation an populate the original surface.

I did a workaround where I displayed all geometries in the viewport and converted to .vrproxy which I where able to instance over the tiles.
But this process is tedious to update and is very limited because of GPU memory while creating the .vrproxy and RAM while rendering.

Is there a other way to achieve what I'm trying to do?

You can use nested ForestPacks:


Currently there is a bug when using nested FP items. Inner Item mus be set to Meshed mode [Display Rollout].

Thanks for the tip Rokas, it worked like a charm.

I updated my scene and I can now update the look without having to export .vrproxies

However I still hit the RAM limit when I use Meshed Mode for the inner item.

As I understand the documentation I lose the instancing from my original geometry when I use nested forest so I'm not surprised it overloads the RAM when combining everything in to a giant mesh.

You mentioned that there currently is a bug preventing Nested Forest to be used in Automatic mode.
Is it something you are working on and if so when do you believe there will be a new version?

I'm willing to try a nightly build if possible.

I did attach a render where I reduces the amount of grass, trees and bushes to be able to render the scene. But as you can see I would need a lot more of everything to cover the surface. (Nested_Forest.JPG)

And my previous attempt with VR-Proxies, which is more of what I'm aiming for. (VR-Proxy_Forest.jpg)
