New to discord, having an issue I can't solve with OB. This first screenshot is from the apps camera

New to discord, having an issue I can't solve with OB. This first screenshot is from the apps camera that I used in this painting a year or so ago. The foreground and background strokes are blurred, but there is no blurred vignette. I have since gone back into the same painting and tried to take photos, but there is no blurring effect at all. Was this in an update to the app?

Kind of a circular problem. Once the tools are built, and a community starts to really take shape, art blitz them on twitter.
Going to have a hard time pushing for integration until there's something fully defined that they can look at and go, ya, worth doing

"A year or so ago" would have been before Open Brush was released. So - did you take this screenshot in Tilt Brush? Our first release was in January this year.

andybak•11/10/21, 10:02 AM

If it was Tilt Brush, then it's a bunch of stuff was changed by Google to make it possible to release as open source and it's hard to track down all those differences. If you just mean "I used an earlier version of Open Brush" then I might be able to dig a bit deeper to see what changed.

annahoo.OP•11/10/21, 5:49 PM

It was 100% open brush as my painting is still in there, and I've taken screenshots within the OB app since and they don't look similar, everything is in focus.

andybak•11/10/21, 7:01 PM

I'm a bit stumped. We've never had a depth of field effect. The 1.0 release didn't have bloom but it was then fixed. Multibrush had more effects but you're certain it was Open Brush... The only effects I'm aware that we've ever had is Bloom and Vignetting. I guess bloom could be mistaken for a depth of field blur - but it responds to brightness - not distance between the brush-stroke and the camera.

Uki Maru•11/10/21, 10:54 PM

In the experimental build, I see that the pictures taken do have a depth of field like effect. @annahoo. is this the kind of blur you are talking about?

annahoo.OP•11/10/21, 10:58 PM

Definitely not vignette because I customized the config file specifically to get rid of that (and have been able to toggle it back on and check to make sure it's not the effect I'm looking for). I haven't downloaded multibrush either. That might be the effect, I'm not sure, I've got another photo take in app of the same painting, different angle that might also show the effect better

annahoo.OP•11/10/21, 10:58 PM

it doesn't appear to be color related

Screen_Shot_2021-10-27_at_3.40.13_PM.png

annahoo.OP•11/10/21, 11:01 PM

where as now, same painting in OB, the background/foreground blur isn't happening.

annahoo.OP•11/10/21, 11:02 PM

I've always used the in-app camera, not the quest camera.

andybak•11/11/21, 5:51 PM

Yeah - I completely forgot about the Tilt Shift:

andybak•11/11/21, 5:51 PM

That is exactly what you're describing

andybak•11/11/21, 5:52 PM

Now - the question is - why isn't it coming out on screenshot?

Aandybak Yeah - I completely forgot about the Tilt Shift:

annahoo.OP•11/11/21, 6:58 PM

Thank you so much! I appreciate the help very much. Not sure how I can 'activate' that again though?

andybak•11/11/21, 7:01 PM

No. It's something we need to from our side. I'm just curious if anyone else has noticed this. Searching the discord I can see people complaining about too much tilt shift but nobody commenting on the fact that it suddenly disappeared entirely. It's be grateful for some input from other artists.

VR Rosie•11/11/21, 9:54 PM

Interesting! Yeah all pics from Open Brush I have taken recently don't have this Tilt Shift anymore?

VR Rosie•11/11/21, 10:00 PM

I never noticed because I use the experimental build a lot now

VR Rosie•11/11/21, 10:14 PM

Oh I was a noob and had post processing off hehe, changed that and now I have Tilt Shift on Steam, Oculus and even tried the Beta branch too and all have Tilt Shift on

andybak•11/11/21, 10:19 PM

hmmm. ok. so my next suggestion for @annahoo. - can you try removing your Open Brush.cfg entirely? (move it somewhere else and restart the app - you can move it back afterwards)

VR Rosie•11/11/21, 10:30 PM

Tried Quest too, all good, no issues with Tilt Shift my end.

annahoo.OP•11/11/21, 10:53 PM

OK just removed the config file, went into the same painting and took a screenshot and this is what it gave me. Vignette blur yes, but not the tilt shift

andybak•11/11/21, 10:57 PM

Not sure what you mean by "vignette blur" (the vignette effect darkens - it doesn't blur) - that looks like tilt shift to me

annahoo.OP•11/11/21, 11:02 PM

ok by vignette blur I just meant, it's blurred where vignette would typically be, the outer edges. That's not the effect I'm trying to get back though. If you check the edges of my first screenshot that I'm trying to recreate, the bottom right corner in the orange for example isn't blurred, but the black marks in the foreground are, as are the peach and orange marks in the background

Aannahoo.ok by vignette blur I just meant, it's blurred where vignette would typically be...

andybak•11/11/21, 11:03 PM

that image looks cropped (the aspect ratio is different) - do you have the original?

andybak•11/11/21, 11:04 PM

you're right though. it does look like depth of field.

annahoo.OP•11/11/21, 11:04 PM

Unfortunately no, I grabbed that from my instagram, I had deleted the original.

annahoo.OP•11/11/21, 11:05 PM

It reminds me of an expensive camera lens that blurs the background and foreground, it's just such a nice effect that I'd love to keep incorporating into artwork

Does AudioReactivity work in Unity if there is an audio source?
For either an OpenBrush or Tiltbrush scene?
Does it have to be enabled somehow?

andybak•11/12/21, 9:41 AM

Can you explain what you're doing in a bit more detail? Specifically the "in Unity" bit. Are you using the Unity SDK (or Toolkit as it's also known) to import an exported sketch into Unity?

VR Rosie•11/12/21, 9:41 AM

Should do as long as you have the SDK dropped in, haven't experimented with it myself but I remember seeing a demo scene about it in the SDK somewhere showing the music reactivity working?

andybak•11/12/21, 9:41 AM

There are some docs here: https://docs.openbrush.app/user-guide/open-brush-unity-sdk#_st8oph1ghsgx

LucyBW•11/12/21, 4:00 PM

Thanks @andybak and @VR Rosie

Figured it out!
There is a Tilt Brush Audio Reactivity prefab in the Tiltbrush/Prefab folder.
You have to drag it into your scene. The prefab provides an Audio Reactivity Manager script that computes all the beats which are used by the TB shaders.

andybak•11/12/21, 4:02 PM

Cool. Were the docs any help?

LucyBW•11/12/21, 4:08 PM

Well I figured it out last night before your message. But thanks so much.
In the end I read the shader code, saw that they were drawing values generated by a script. I was about to put the script in my scene when I figured there has to be a prefab for this.... And found it!

LLucyBW Well I figured it out last night before your message. But thanks so much. In the...

andybak•11/12/21, 4:23 PM

Well to be fair - I never read docs either!

Aandybak Well to be fair - I never read docs either!

LucyBW•11/12/21, 4:38 PM

Actually that doc has a section on Audio Reactivity which exactly explains the prefab!
Would have been perfect last night. Lol!
Well good to know about the docs...

I apologize for repeating myself but I asked a few days ago about an issue im having with both open and tilt brush. Its just black screens, i can see and move my controllers but thats it. Im on pc vr. I would appreciate any help

AncientWorlds•11/14/21, 11:06 AM

That happens when oculus steam and unity aren't loaded in the right order or inside unity when its in error report mode.
Not a dev so don't have deeper insights than that.
Might help if you mentioned the headset you're using and any other relevant info you can think of that might be useful in troubleshooting/replicating.
Which version are you using and how recently have you updated?

UUNGOVERNABLE I apologize for repeating myself but I asked a few days ago about an issue im ha...

andybak•11/14/21, 2:27 PM

Might help if you mentioned the headset

@AncientWorlds - They posted that a bit further back:

I’m sorry I should have included this to start with. I’m on windows 10 with a valve index,

@UNGOVERNABLE - AncientWorlds might be on to something. When you launch Open Brush - have you already started SteamVR? Can you see the home or the blue grid plane in the headset?

This is clutching at straws a bit as I've not come across this before as far as I can remember. Anything else unusual about your setup that might give us a clue?

UNGOVERNABLE•11/14/21, 3:55 PM

Im on the most recent version of both open brush and steamvr, everything else works without a problem. I've tried both launching open brush first and opening it while in steamvr. I've validated files, reinstalled, deleted all the files and then validated again. Nothing seems to be working

andybak•11/14/21, 4:07 PM

I don't suppose you've got access to a different PC you could test on? Although my hunch is that would probably just work

andybak•11/14/21, 4:07 PM

I don't have an Index myself but I'm pretty sure we'd have heard if there were issues running on the Index

andybak•11/14/21, 4:14 PM

Can you delete the entire assetCache folder that is in the same folder as the log?

UNGOVERNABLE•11/14/21, 4:15 PM

yes

UNGOVERNABLE•11/14/21, 4:15 PM

is there anything else to delete or should i try launching it

UUNGOVERNABLE yes

alright
