Octave3D-Level Design - Snapping, Prop placement, Multi-Prefab painting

The Delete button doesn't seem work in the text boxes, the backspace is fine.

 

The Octave editor is causing a stack overflow.
It'll work sometimes for a bit and then freeze up and crash the editor. But it freezes for very long amounts of time randomly and will keep working again.

 

Hello,

I believe I have already fixed this error. Are you using the latest version?

 

Yep it's on version 2.3.1 on Unity 2019.3.14f1

 

Hi, I recently bought your tool, it works really well but i am having some trouble with using terrain! I have got gaia 2 and been trying to add the terrain as a prefab to use ( Not sure if this is what i need to do to get it working ) But it says Terrain is not an allowed component! When i just have the terrain in the scene, even with refreshing scene it wont let me place on top of it

There are some buildings placed ontop and i can interact with them but just not the actual terrain! Have you got any advice?

Thanks

 

Hello,

Terrains do not require any special placement mode and don't need to be prefabs. You can place them in the scene pretty easily with the Unity placement tools. But the plugin allows you to populate the terrains with objects using the Decor Paint mode. Also, please make sure the terrain has a terrain collider attached to it.



Cheers,
Andrew

 

Hey Thanks for your reply, that is what i thought was meant to happen but its not! So i have my terrain saved as a prefab, its got a terrain collider on. When i try to add the prefab into the prefab categories I get this warning message and no prefab in the list. you can see the warning in the console.

Terrain[] terrains = prefab.GetComponentsInChildren<Terrain>(true);
if(terrains != null && terrains.Length != 0)
{
if (logWarningMessages) Debug.LogWarning("The prefab '" + prefab.name + "' contains children with a 'Terrain' component attached to them. This is not allowed.");
return false;
}

If you can see on the screen shot i have the terrain prefab in the inspector so you can see what its got.

Hope you can help!

thanks

 

You don't have to put the terrain in the prefab manager. Just put in the scene. The prefab manager should contain the props (i.e. objects that you will place on the terrain).

 

Ahh ok thanks!! Its working now, i re watched your tutorial vid aswell so that explained its only decor mode! ( i was trying path & block )

thanks for the help, really nice tool! will leave a review for it soon

 

Glad to hear it works

A review would be welcome. Thank you.

 

Can anyone post a premade configuration file for the Prefab Categories for either any of the 3DForge assets or Multistory dungeons please?

 

The object selection options for Octave are not very visible, it's not obvious to tell which option is selected, the only indication is that the icons are slightly greyed out. I find this is not very user friendly. Is there a way to make them into buttons like in the video tutorials please?

Perhaps change the background of the button to a darker grey would be a good approach

 

Any comment on this?

 

I've made the selected button green. Please send me an e-mail at octamodius@yahoo.com so that I can share the updated package with you.

 

Thank you.

 

If anyone else would like better buttons like mine, just modify these files:

Assets\Octave3D World Builder\Scripts\Inspector GUI\Toolbars\

    \ObjectSelectionTransformGizmoSelectionToolbar.cs

    \ObjectPlacementModeSelectionToolbar.cs

    \InspectorGUISelectionToolbar.cs

Change the Color in the following method in each file to:

Code (CSharp):

1. protected override Color GetButtonColor(int buttonIndex)
2. {
3.     if (buttonIndex == GetActiveButtonIndex()) return new Color(0.8f, 0.8f, 0.8f, 1f);
4.     else return Color.white;
5. }

 

Is there a way to align the grid with an already placed object vertex?

 

Hello,

No, I'm afraid not. This feature is not available.

 

Good day, I am trying to import a number of *.prefab files that are not appearing in the Prefab manager window. Various other prefabs are importing just fine. I've double checked that the files which aren't importing are actually *.prefab and not *.FBX. Is this a known issue? I tried to look up the issue on this forum but didn't find a solution.

 

Hello, another issue: When hitting Play, I get the following compile error:
Invalid editor window O3DWB.PrefabTagsWindow
UnityEditor.EditorApplicationLayout:FinalizePlaymodeLayout()

It looks like someone reported a similar error on Aug 2019, but I found no solution from Asset developer.
https://forum.unity.com/threads/oct...i-prefab-painting.425240/page-17#post-4843859

Help would be appreciated.

 

Terrain prefabs are not supported. If the prefabs contain a terrain in the hierarchy, then it won't load in the manager.

Regarding the second issue, I don't know what is causing that, I will check to see if I can reproduce it.

 

This *.prefab does not contain a terrain in the hierarchy. Let me know if you want me to send you the prefabs for reproducing the issue.

 

Yes, this is done intentionally. There is no need to add terrains to the prefab manager. The prefab manager should contain the mesh prefabs that you can pick and choose to place in the scene. Just place the terrain manually in the scene as you normally would then add the props to the prefab manager and start populating the terrain.

 

Hi, I should have clarified: I am not working with any terrain. I said that there is no terrain in the hierarchy because you had suggested that might be the case for me, so I wanted to clarify that there isn't any terrain involved. So to restate:

1. I am not working with terrain.
2. There are prefabs which for some reason are not getting imported into the prefab manager, while others are.

I am ready to send you the prefabs for analysis if you're still not able to figure out the issue.

 

I haven't look over it yet because I didn't think there was an issue. You can send the prefabs and I will look into this when I have the time. One prefab should be enough.

 

Use Octave3D2.3.1.1 to create a new prefab, place the new prefab, and then switch to the selection mode, press the G key, the same type of object will not be selected, and it becomes a deleted object. You need to close unity3d2019.3.15 and reopen it Unity3d2019.3.15 is back to normal!

 

I'd really be interested in a copy of someone's Prefab settings for either Multistory dungeons or any of 3D Forge assets. Please.

 

do these guy not have a discord??? I'm having such an annoying problem with assets being offset from the grid but no place to look for help. uggg

 

I don't have discord. You can use the e-mail and forum for support inquiries. Please give me more details about the issue you are encountering. Screenshots would be welcome if possible.

 

so this is the official forum?

The problem I'm having is that the assets don't always snap to the grid. but instead are offset by half


This even happens when you reduce the scale of the grid. only fix I know of right now is to start my unity project over every time.

 

You probably have the Use original pivot toggle checked. In the Snap Settings UI, you will have to uncheck this toggle:


When it is checked, the tool will use the pivot of the mesh as defined in the modeling package.

At least, this is what I think it is judging from the images.

 

Is there a way to ignore some placed meshes so you can work around them more easily without constantly selecting them. I made a pipe and wanted to duplicate it but when I do I just end up selecting the building around it. any tips?

uggg

 

the problem is we need to use the original pivot based on how we built the kit. the kit checks out and should snap to grid. I found when closing unity and reopening it fixes its self but that is a massive pain

 

Hello,

Yes, the default behaviour is that it selects entire hierarchies. In the object selection settings, you can change this by changing the selection update mode to Single Object:

 

Hi, came back after a while back to project using Octave and got 2 questions:
1) i am working on a project with 2 other guys and we are backuping project of course and updating each others changes so we have it all up to date, we are all working on different parts so not messing with others work but... after such project update, i found that i lost my octave settings like prefab manager selections were gone, can you please tell where these settings save, what should i have to back up or pay attention, so i wont loose any progresion in octave

edit: sorry got eyes but i am blind, safe config button, extra file, embarrased

2) using prefab replacement function, sometimes it replaces placed prefab with choosed differen prefab but they are rotated 90°... tried to replace with prefab placed in scene with same rotation, but didnt help. Dunno why it sometimes work, sometimes dont, couldn't reproduce situation

 

Hello,

1. Yes, configs can be used to save this data.
2. so the problem is that the plugin adds a 90 degree rotation to the new prefab? Is this correct?

Cheers,
Andrew

 

Yes, it sometime does this

 

Hi guys. I have a problem. After a few minutes of working with an octave, the next problem will arise. When I press any key CTRL or J, Shift and others, the selected objects are immediately deleted. The fatal error described below appears. Only Unity reboot helps. How can I fix that?

Hi there,

I have released an update today which fixes all sorts of issues. Can you please upload to the latest version (2.4) and see if it works?

Cheers,
Andrew

 

Yep. You are done with it. Good job. Thank you. Octave the best!

 

I'm happy to hear it works Thanks for informing me!

 

Actually, I have one more request. May you do smaller buttons in the tags menu. It will be wonderful.

 

Hello,

I'll see what I can do. Will start looking into this tomorrow and keep you updated.

 

Sure! I'm not hurrying. Maybe it is interesting for you. When I try scale objects with CTRL, some times adjust the object to zero. And I have a critical error. Not a big error. Just you know.

transform.localScale assign attempt for 'Wall' is not valid. Input localScale is { -1.000000, 1.000000, NaN }.

Hello,

I have updated the button tags and fixed the scale gizmo error. Feel free to send me an e-mail at octamodius@yahoo.com and I will send you the updated package.

Cheers,
Andrew

 

Hi, thanks for update, but since i updated i got this problem.
When using object selection tool, i got last object selected when using object placement tool still snaped to cursor, so when i wanna select something and work with it, its in the way since its on cursor like when placing objects.... before update it worked fine... or anyway, how to disable it?
...btw same with object erasing

 

Hi there,

I'm afraid I do not understand fully what is the issue you are encountering. Can you please explain step by step the symptoms?

Thanks,
Andrew

 

edit: sorry,,,, just wanted to record video with it and now its all ok... i guess after update, i didnt restart unity or laptop yesterday.... so that helepd i guess, sry

 

Ok. Glad to hear it's working

 

Hi.

I recently bought Octave3D as it seemed like a really good tool that with a fairly intuitive interface for a beginner game designer. I've been learning as I go and am enjoying its functionality when it comes to building with modular sets, in particular. However, I've also encountered some issues, one of which both my more experienced friend and I have not been able to solve. I'm wondering if it's a bug.

The issue is that Octave's mode keeps getting "stuck" in placement mode. It's not actually that the mode fails to change. Instead, the mode (and the GUI) changes, but the active prefab doesn't disappear (or disappears for a split second then reappears). It then becomes impossible to use other modes. Instead of selecting or erasing the object I click, it just places another of whatever prefab I have active. I can change the active prefab and the problem persists.

As for what causes this, I really have no idea. I'm a beginner, but I'm not actually changing any settings, besides switching modes. I'm just placing away with my objects, then switch modes to select or erase something and it gets stuck just like that. The only thing I have noticed is that it tends to happen if I haven't taken any action in Octave for a short while (it usually seems to happen after I've been thinking for a moment about how to lay the next part out, etc).

This is also a very frequent problem, sometimes to the point that it seriously inhibits my ability to make progress. The only solution I have found is to reopen the whole project. And even this sometimes fails to work.

Is there a simple reason for this happening that I'm just not aware of, or is this a bug?

Thanks.
~~~

Edit: I do recall one thing that might be the cause. When I imported the asset, there was a message saying that it had certain package manager dependencies and asked if I would like to update. On my first import, I told it to update. This added the Package Manager UI package from Unity, which caused several hundred namespace errors to occur. At the advice of my friend, I removed that package and re-imported Octave3D, choosing to skip the update this time. That appeared to solve that problem, but is there anything in that dependency that would be causing the issues I have been having?

Edit 2: I just read Xanisko's post, and it sounds like they might have been experiencing the same thing and just struggled to describe it.

I'll let you know if I solve it in the meantime, so as not to waste your time. Also, I'll throw in any other issues I run into:

-- Like the main issue, another random trigger where for no apparent reason, pressing any key will cancel the active prefab. For example, attempting to rotate the camera by holding Alt and moving the mouse will cause the active prefab to de-register, and it must be selected again to place. This also means that prefab-active hotkeys (such as U to toggle object-to-object snap) do not work during this problem.
