Also, do you know why, when I restart Unreal, the static meshes are hidden and I need to run Cleanup and Generate again when using the Default Tool inside the PCG Modes?

It the issus for the default tool. I don't know why I didn't notice. The spline upper left I use GPU for spawning the mesh. And I need to regenerate.
Do you have any idea about the video I show? The Point doesn't existe any more, when I exit and reopen the projet.

That's weird I can't repro on my end. I tried with the scatter tool, paint, save, quit, reload, inspect the tool data and it is there.
Also the fact that the paint tool is not available is because you need to have nothing selected for it to work.
I'll try again in 5.7
What's also very weird is why you don't have anything executing, like the graph is disabled and not executed. Is there anything in the logs?
Can't repro on 5.7
But from what I see in your example is that you are losing your Root Component on load
Without a root component, you can't generate anything (no bounds) hence why is seems disabled. And you can't paint on it either (it's the same than the PCG World Actor for example).
As for why you have to Cleanup/Generate for the default tool with the splines, it's because if you don't have anything to spawn (Meshes or Actors) it spawns those tripod debug meshes. As I said, debug meshes are transient and not saved. But the graph is marked as generated, so trying to generate only will do nothing (as for the system, everything is already generated, so nothing to do).

Thnaks for your awnser @craggy falcon .
Here my PCG files. I you willing to look there noting special about it. It base from the tutorial of @earnest trellis. But my procedural lead team, want I test some features of 5.7 before they in couple month.
I have this error when I open my project after painting with my tool.
LogPCG: Error: [RegisterOrUpdatePCGComponent] Component has invalid bounds, not registered nor updated.

I was able to reproduce on the vine tutorial I did. I re-opened the project I had, I saw the vines. I went onto the Get Tool Data node and pressed "A". Everything got disabled cause no points.
Cleanup / Generate doesn't recreate it cause it doesn't read the painted points anymore. So anything that would cause an update to the graph to regenerate it will result in everything disappearing.
You can try with this project too. You should see the vines but once you go and try to get the painted points it'll all go poof.

@craggy falcon Any Idea how to figures out a solution ?

this doesn't seem fixed on 5.7.2
We would like to use PCG tools in production but this is a major issue @craggy falcon
earnest trellis
Same here. And I'm now having to tell people to be careful or not use the PCG mode tools because of that and the spline draw tool spacing not being controllable. 😢
craggy falcon
I was able to repro for the root component disappearing, I'll log a Jira on our end and try to target 5.7.4

Same for that, I'll Jira it and fix it for 5.7.3, as it is a very simple one.
earnest trellis
Thank you very much! ❤️
These tools are awesome, especially the drawing one, so it hurts to have something awesome given that trips at the end. 😅
Looking forward to 5.7.3 already
craggy falcon
Actually 5.7.3 is already closed so it'll have to go to 5.7.4
craggy falcon
I'm sad too, I didn't realize 5.7.3 was so close from 5.7.2
earnest trellis
Some might say it's 0.0.1 close 😛
halcyon warren
thank you!

Little update on this one: We found the issue and potentially a fix that should resolve it in all those cases. If all goes well, it should be in 5.7.4
This only happens on actors that are spawned by the tool and don't have a root component, like a simple Actor does, if the actor already exists in the world with the right component or has a root component by default like in a BP, then you're fine.
For example, just creating an empty actor class as a BP and use it as the default actor for the tool will work.
This is not really a good workaround, it will probably not work everywhere so you should probably wait for 5.7.4, but if you want to test the flow on your end before that might be acceptable

How can the ones spawned by the tool not have a root component? Isn't that just a basic actor in both setups that it attaches itself to?

They do have a root component. Just that they are marked transient and the flag is never cleared. So they are not saved and on reload they disappear

By the way this is submitted in Dev-5.7, so it'll be in 5.7.4. If you wanna cherry pick it: https://github.com/EpicGames/UnrealEngine/commit/7cd08b394251702ca3f9360acd153983b9a2dfc4
