There's pretty standard "spherize" and possibly "cubeize" deformers in blender and other 3d packages

There's pretty standard "spherize" and possibly "cubeize" deformers in blender and other 3d packages. I'd use a blendshape to morph between the two. It's a pretty well established technique.
Blendshapes pretty much "just work" when imported into unity.
Then you could maybe animate the blendshape either directly in playmaker or by creating a 2 frame animation and playing it back in playmaker.

Blender 2.8 Tutorial: Cast Modifier

Use Blenders cast modifier to blend between shapes.

Blender Docs
https://docs.blender.org/manual/en/latest/modeling/modifiers/deform/cast.html
The Cast modifier shifts the shape of a mesh, curve, surface or lattice, towards any of a few predefined shapes (sphere, cylinder, cuboid).

It is equivalent to the To Sphere tool in Edit Mode, and what ...

This might be exactly what you're saying but it's worth spelling it out - you can use cube or some other regular shape as a midpoint to morph any two meshes into one another. Just morph mesh1 into a cube (or whatever), instantly switch to the other mesh pre-morphed into a cube and then animate that turning back into mesh2.

andybak•12/6/21, 8:56 AM

The materials might flip at the changeover but you can animated fading them to white or black or something as well.

andybak•12/6/21, 8:58 AM

(there are algorthithms that morph arbitrary meshes into one another. It was called "Conform" in 3Ds Max I think. But they never work that well unless both meshes have a ton of triangles)

chardOP•12/6/21, 9:01 AM

Yeah sorry my explanation was awful

chardOP•12/6/21, 9:03 AM

Basically -

Blender cast modifier to morph a mesh into a cube.
Duplicate the mesh & use a blendshape to save the morph into the mesh.
Export the mesh as an FBX with blendshapes turned on.
Import the FBX, you'll see a new blendshape slider on the import window
Set up an animation controller, the first animation with blendshape off the second with it on. You can control this with parameters from playmaker

Cchard Yeah sorry my explanation was awful

andybak•12/6/21, 9:03 AM

I didn't watch the vids to be fair. They probably made things clearer.

andybak•12/6/21, 9:04 AM

Completely different look - but it's another approach.

andybak•12/6/21, 9:04 AM

You can have a ton more particles if your hardware is up to it and get a fairly solid surface.

andybak•12/6/21, 9:05 AM

(also - it can get the colour from the texture map and even respect lighting)

chardOP•12/6/21, 9:06 AM

Oh yeah I did that last month, it's only possible by using particles on the mesh though it is really easy.

AncientWorlds•12/6/21, 10:10 AM

That's all pretty wild.

thank you sooo much @chard @andybak !!!!

AncientWorlds•12/6/21, 12:10 PM

Is there a quick and dirty way to reduce audio input volumes or mute in unity or prevent the video recorder from finding the audio source?
maybe just force the recorder to fail when looking for audio sources?
I'd prefer to be able to just change a script or have a command line entry, rather than post process using the batch file
Around 90% of the time I'm listening to windows media player when using open brush, an typically shoot around 10 videos a session
It would be nice to just be able to post them rather than do additional editing to get rid of unpostable audio

andybak•12/6/21, 12:40 PM

Can't you just change your audio input to something else in Windows?

andybak•12/6/21, 12:40 PM

I guess that requires you having an input that is still there but does nothing. I've got Virtual Desktop microphone that works like that when I'm not using the app

Aandybak Can't you just change your audio input to something else in Windows?

AncientWorlds•12/6/21, 1:11 PM

Maybe. Makes sense, didn't think of it. I have a microphne on another headset that has a mute switch, will try that.
Thanks!

chardOP•12/6/21, 1:12 PM

I use Mute.FM. it mutes your specified music player when it detects any other audio source (you have granular control over what that is)
Idk how much control you have over the fade time or reaction time, but it's not immediate on the stock version.

Hmm. "Usually requires flash", is that actually the case?

AncientWorlds•12/6/21, 1:51 PM

That worked once. Then I got what I'm pretty sure is an unrelated video error, and it found the actual music source.
Going to try it again and remember to save changes, see how it goes

AncientWorlds•12/6/21, 2:03 PM

Really strange. Didn't have the error this time. Worked on the first video pass. After that, it apparently discovered the audio, or maybe the headphones found it.
Will try the method Chard suggested

What’s the most current version of Unity that OB supports??

2019.4.x

andybak•12/6/21, 4:00 PM

It already does, I believe.

andybak•12/6/21, 4:01 PM

Can you try it and let us know if there are any problems? I think there's maybe an issue with two versions of the json library being installed but it's a while since I tried it

andybak•12/6/21, 4:02 PM

(it's a bit more fiddly getting it working with URP or HDRP - that's still a work in progress. Partially done)

Zandy•12/6/21, 4:02 PM

Haven’t tried it yet. Didn’t want to dig into it and have things not work. Awesome news.

. I will let you know. Got a project that will require the new version but it’ll be a week or two from now.

mikesky•12/6/21, 4:03 PM

Yeah render pipeline is only thing that'll be an issue, if it's standard, you're fine!

andybak•12/6/21, 5:10 PM

In theory - the docs should explain all this properly. https://docs.openbrush.app/user-guide/exporting-videos If they don't then it would be a good opportunity to fill in some gaps

mikesky•12/6/21, 5:11 PM

You'll want to disable the watermark in the config file: https://docs.openbrush.app/user-guide/the-open-brush-config-file

"Flags":{
"ShowWatermark":false,
},

The Open Brush config file

Slyman•12/6/21, 5:11 PM

ok SO higher res can be rendered offline hey

Slyman•12/6/21, 5:14 PM

Cheers for the watermark tip Mike! Attribution of open brush will be with my project, just preferably not directly on screen ahha

Slyman•12/6/21, 5:15 PM

thanks for the quick response guys, looks like this rendering offline videos .bat system will give me everything I need

AncientWorlds•12/6/21, 5:16 PM

That's the key for the watermark.
Resolution can also be set in the config, although it's capped at some point, I'm pretty sure
Offline res can be higher

Slyman•12/6/21, 5:18 PM

ooh, if I can render paths within OB at 1080p that'd be my preference. Looking at this offline rendering system my eyes are going a lil crosseyed. at the limit of my mental comprehension

Slyman•12/6/21, 5:19 PM

so of those edits there @AncientWorlds which is the one that I can change my render res from camera with?

AncientWorlds•12/6/21, 5:24 PM

SnapshotWidth and SnapshotHeight set the frame size for the standard camera.
You will probably want to set "ShowControllers: false,
Good idea to make a backup of your original incase you accidentally delete a bracket, or comma or something, or want it back again
Maximum camera rez depends on your systems ability
Video, I think is capped at 2048, but it might be higher.
For the Video camera, change the number for "Resolution": ####,

Slyman•12/6/21, 5:24 PM
