yeah currently it looks like clicking the asset to load the thumbnail will create the object. And I think clicking the thumbnail again just duplicates it into the scene

andybak•8/21/22, 8:40 AM

Loading the scene twice works. So first time is correctly initing the thumbs but not the scene models.

omn0mn0mOP•8/21/22, 8:41 AM

Huh interesting

andybak•8/21/22, 8:41 AM

Probably related to async completion.

AssetPreview looks like it's Editor-only

Aandybak Remind me what you're doing with the API and teaching?

For context: currently in med school. I'm working with the anatomy dept to create interactive VR learning modules. Currently, they use this thing, but it has a lot of limitations: https://www.medicalholodeck.com/en/

Ah yes. I remember now.

andybak•8/21/22, 8:43 AM

Did you do some stuff with displaying volumetric textures as well?

omn0mn0mOP•8/21/22, 8:43 AM

The goal is to use Open Brush's more robust drawing tools to be able to highlight structures (arteries, nerves, surgical landmarks) and then compare what the student draws with an answer key drawing

andybak•8/21/22, 8:45 AM

We've added point cloud import recently. Adding DICOM support would be a nice addition too.

andybak•8/21/22, 8:45 AM

Import ALL the things!

andybak•8/21/22, 8:45 AM

(had the urge to add MagicaVoxel support the other day too...)

omn0mn0mOP•8/21/22, 8:46 AM

I did not, but it looks like gltfast has an extension that adds support for it

Wait nvm, it's just a planned feature https://github.com/atteneder/glTFast/issues/209

andybak•8/21/22, 8:49 AM

For any importer that doesn't insist on async it's pretty trivial to add support. I think point cloud import took me half a day.

andybak•8/21/22, 8:49 AM

I want to replace the obj importer too so it works on the Quest.

andybak•8/21/22, 8:50 AM

(Parsing obj files is pretty damn simple. I got a basic one done from scratch for my generative models branch)

andybak•8/21/22, 8:51 AM

Of course - re-exporting is tricker if the result isn't a normal mesh

omn0mn0mOP•8/21/22, 8:52 AM

It's funny how Unity is supposed to be this amazing cross-platform engine, but then there's so many things that don't work with VR cuz of the quest being Android

omn0mn0mOP•8/21/22, 8:52 AM

Still trying to find a (FOSS) webview solution :)

So sad that they're all like $150

andybak•8/21/22, 9:11 AM

A webview is such a huge blob of code, it would be better if each platform exposed it as part of their API

andybak•8/21/22, 9:13 AM

but then there would always be a few platforms that didn't so we could never rely on it 100%. Which means I guess we'd probably go back to wanting an embedded solution

re: Layers. I decided to go ahead and implement "Objects remember what layer they came from and return there when deselected"

andybak•8/21/22, 10:07 AM

but because I'm lazy and it was tricky - I actually implemented "A selection remembers the layer that the last object added to the selection came from"

andybak•8/21/22, 10:08 AM

Which is interesting because it means that in simple cases things work as expected.

andybak•8/21/22, 10:08 AM

But if the user does this:

Select some stuff from Layer 1
Switches to Layer 2 and selects some more stuff
Deselects everything

andybak•8/21/22, 10:09 AM

then the stuff from Layer 1 moves to Layer 2. Hey presto - a way to move stuff to a different layer without needing a specific button.

andybak•8/21/22, 10:09 AM

It's a bit of an "easter egg" feature but I wonder if it's a rare enough use case and rare enough to do my accident that we can leave it in?

andybak•8/21/22, 10:10 AM

@bootleg @ancientworlds waddya think?

Bootleg•8/21/22, 10:11 AM

to me personally it sounds like it can easily go wrong for specific types of artists

Bootleg•8/21/22, 10:12 AM

I often struggle to keep up with layers in traditional drawing applications and finding out later that layer magic messed up my work is immensely annoying

Bootleg•8/21/22, 10:12 AM

considering that layer UI is even less visible in Open Brush, I'm concerned that this might end up messy

andybak•8/21/22, 10:12 AM

Yeah. I've also realised that my brain is too small to figure out how this interacts with undo.

andybak•8/21/22, 10:13 AM

Back to the drawing board! Looks like we need to track original layer for every item in a selection. Or - prevent selections from spanning layers entirely. Which might be intuitive.

Bootleg•8/21/22, 10:13 AM

Or - prevent selections from spanning layers entirely. Which might be intuitive.

I think this is for the best

andybak•8/21/22, 10:14 AM

I actually meant to write "unintuitive"!

Bootleg•8/21/22, 10:14 AM

it's intuitive to me

andybak•8/21/22, 10:14 AM

i guess we need to make it clear to the user why they can't add to a selection after switching layers

Bootleg•8/21/22, 10:14 AM

I guess so

Aandybak @_bootleg_ @ancientworlds waddya think?

AncientWorlds•8/21/22, 11:04 AM

I think I'd have to try it to actually know for sure. Personally I'd prefer a clearly visible option so I know whether I'm spanning layers or working within a scope such as a layer or group. Probably more work. I think Bootleg is correct about visibility and confusion with layers, something I talked about in my long comment.
Probably sufficient to limit to layers, at least in the initial form, since I can always put an object on its own layer (I think). This would give control over things like brushes and color changes, would rather have that than an automatic global effect for things like brush/color changes.
I expect to be doing a lot of rebrushing when all these tools get synchronized together

andybak•8/21/22, 11:11 AM

Everything is in the beta. It's "testing how the tools work together" that we hope people are already doing!

andybak•8/21/22, 11:11 AM

Rebrushing has been released. And layers is beta
