[FP 6.2.1] Cleaning Surfaces
« on: September 28, 2020, 03:27:31 PM »
Hello !

We have made multiple Forest on huge surface (aka high polycount).
Now i'm satisfied with my forest, i'd like to 'collapse' it, and keep a non-procedural Forest to delete my Surfaces objects.


- Here's the first method i've tried :
> create an empty forest
> convert to custom edit
> attach my original forest

That's pretty munch what i need BUT, some transformations are not correctly imported.

Here's a simple scene : plane + noise, teapot distributed. Green is the original forest, red is the attached one. All the distribution are good, but all item in the red forest have a Z at 0 (just like if the noise was off)


- Do you have any other workflow to collapse a forest ?
I can try the forest tool : instantiate but we have pretty huge number of items distributed.

ForestTools are the recommended workflow.

I call collapsing is the process of eliminating ForestPack usage.

My first goal is 'freeze' the forest to delete Surfaces objets

You can convert to custom edit mode ant then delete the surface.

That's what i thought but i have a different render between original & converted one.

I'm trying to isolate why...

It looks like it comes from random transform.
If i disable it, i have the same render, if i keep transform i have a difference.



Strangly, if i disable transform, switch to custom edit and re active transform, it looks like to works fine   ôO


I'll continue furthers researches

Hello again !

I can confirm that i've found a bug.

Random Z transform is not took into consideration when switching to Custom Edit mode.

Here's a simple scene (3ds 2021.3, FP 6.3.0)
Plane & teapot. Add random Z. Copy forest and switch it to custom edit.

Can you confirm this ?
This will likely leads to forbid this option in production.


Thanks
