I hope this is the right place to ask. I am trying to import a tiltbrush.glb file into unity version

I hope this is the right place to ask. I am trying to import a tiltbrush.glb file into unity version 2020.3.7 for a coursera project.
Here’s what I have set up so far:

the toolkit sdk
-steamVR plugin
-I am using the provided steamVR camera at the default settings
-valve index headset
The problem is when I run it, in the headset the right side view is dropping some of the brushstrokes. The left side view shows everything. I am not sure how to troubleshoot this and any help would be super appreciated. Or if someone could point me in the right direction that would be great too! Thanks so much.

So - 1. by "right side view" do you mean "in my right eye"? Or something different?

FryMamaOP•1/12/22, 7:19 PM

yes right eye/left eye sorry about that.

andybak•1/12/22, 7:19 PM

Oh no. I see. You mean "Scene view" vs "Game view"

andybak•1/12/22, 7:20 PM

or not!?

andybak•1/12/22, 7:20 PM

top pic definitely looks like Scene View. And bottom is Game View.

FryMamaOP•1/12/22, 7:20 PM

yes in game view. Sorry I'm just learning Unity.

andybak•1/12/22, 7:20 PM

no worries. just need to understand

FryMamaOP•1/12/22, 7:21 PM

but the problem happens in game view

andybak•1/12/22, 7:21 PM

so the question is actually "why are some brush strokes not showing up in the Game View"

FryMamaOP•1/12/22, 7:21 PM

yes. that would be the question.

andybak•1/12/22, 7:21 PM

hmmmm

andybak•1/12/22, 7:22 PM

could you zip up the following folders from the Unity project and send me them? Assets, Packages, ProjectSettings

FryMamaOP•1/12/22, 7:22 PM

well, why are some brush strokes not showing up in the right eye in game view

FryMamaOP•1/12/22, 7:23 PM

andybak•1/12/22, 7:23 PM

so it is eye dependent? If you view it in the headset, is it only showing in one eye?

FryMamaOP•1/12/22, 7:24 PM

yes, the left eye in game view shows everything and the right eye in game view is missing brush strokes. but in scene view I can see everything.

FryMamaOP•1/12/22, 7:24 PM

and yes in the headset

Hi friends!

I need some help with OB files. I’m trying to import into the iPad app Procreate.

USDZ and OBJ are acceptable but they MUST have a UV map attached to it.

I’ve contacted Procreate and their response said “some elements do have UV maps, but not all of them”

Please help! Here's an example of a file that I'm using

mikesky•1/14/22, 2:45 PM

Woah, I had no idea procreate had a 3D mode now! So the incompatibility is probably that the brushes use vertex colours instead of a UV. I believe if you're getting them from sketchfab they attempt to do some of the conversion process but it's only for some brushes. are you working with sketchfab models exclusively or could you try exporting manually from OB?

mikesky•1/14/22, 2:46 PM

Also, may want to give them a poke about supporting glTF models

OBJ is good and simple but not really strict on standards which glTF helps a lot with

mikesky•1/14/22, 2:47 PM

Pipeline is really important, so knowing use cases like this is good for informing future development

andyleo•1/14/22, 5:25 PM

Yeah the 3D painting features are really cool imo. I’m only using sketchfab bc it’s so easy for students to upload. I’m using this in a HS Art class. I’ll look into exporting straight from OB but I’m thinking it’ll make a lot more work for me.

mikesky•1/14/22, 5:28 PM

Another poke for me to get to Icosa integration sooner rather than later

That totally makes sense, I'll see what I can do. What ingest format are you using out of the two?

andyleo•1/14/22, 7:12 PM

“Ingest format”? Sorry I’m new at this

Zandy•1/14/22, 8:52 PM

Just a heads up that the hulls do not have UVs thats why they do not bake properly in unity. You have to bring them into Blender or substance painter to create new ones for them to work.

Aandyleo “Ingest format”? Sorry I’m new at this

mikesky•1/14/22, 10:00 PM

Ah sorry, i mean when it comes into procreate do you use usdz or obj?

mikesky•1/14/22, 10:01 PM

Good to know

Perhaps you might need another step in your pipeline for now, asset prep can be half the work sometimes

Mmikesky Ah sorry, i mean when it comes into procreate do you use usdz or obj?

andyleo•1/14/22, 10:02 PM

I have never done this so I’ll do whichever works. We’ve primarily used the hull brushes so that’s probably bad news

andyleo•1/14/22, 10:04 PM

And I would say that the hulls lend themselves to procreate the best sooo….

mikesky•1/15/22, 3:34 PM

So does it just fail to import if there's no UVs, even if they're blank? I'm surprised because procreate is kinda making it's own UV maps when you paint on the objects

mikesky•1/15/22, 3:36 PM

Zandy's probably right, you may just need to do a bit of pre-processing first just to set them up. Will note this for pipeline improvements though, if that's something we can support our end!

andybak•1/15/22, 6:50 PM

Would be fairly easy to add that to toolkit. I'm thinking of making that more like our general purpose "sketch post processing tool"

sorry if this has been raised before but i cant take screenshots. A black and white box will appear in the screenshot and also in the camera preview

if there a way to fix this?

im using quest 2 on applab

okay further details um it works again if i restart the app but i can only take one screenshot and i cant toggle to other modes (gif etc) before it bugs out again

thanks!!

Ah yeah I think this is known, and also happens in Tilt Brush interestingly! https://github.com/icosa-gallery/open-brush/issues/61 hopefully a fix won’t be too hard

Good evening! Encountering bugs with snap to grid. It’s definitely off. It will snap only in one direction. If you look at the plane or object from a different viewpoint, it’s crooked. Had this issue even building and lining thing up manually. It’ll always be off. The only way to get it perfect is using two guides and snap to x and y, otherwise it’s like the leaning tower of Pisa in one direction.

Evl_Stache•1/18/22, 1:45 AM

@Zandy sounds like you are trying to do something that would be better done in conventional CAD.

Zandy•1/18/22, 1:59 AM

Thanks @Evl_Stache Not interested in CAD. Prefer the painted organic look and feel. Painting architecture in VR is extremely meditative. Like in these: https://youtu.be/wsCo-UmUprE

@Zandy fair call. could be good to have some base geometry to provide a base to paint over

Evl_Stache•1/18/22, 2:52 AM

Zandy•1/18/22, 2:59 AM

For me personally, it’s not the same….I see the advantages of cad programs and blender, etc for buildings but find it’s too clinical and loses the “emotion” that is put in a piece when you paint it organically. You miss the true texture and feel of a painted piece. It’s a completely different experience.

Evl_Stache•1/18/22, 3:07 AM

oh i get you i was more suggesting you could just have a reference cube you paint over that gives you height and square.

Zandy•1/18/22, 4:04 AM

Open Brush and TB have guides that you can use for that.

andybak•1/18/22, 9:21 AM

That's peculiar. I can't even imagine how that would be the case. Do you have any images that show the problem?
