How resource intensive is the icing brush on a scene? I'm wondering if I should use it to paint a go

How resource intensive is the icing brush on a scene? I'm wondering if I should use it to paint a good 500 or so trees or if I would be better using a simple tapered flat brush as my scene would end up lagging to hell

We have a table for that!

andybak•11/5/21, 8:42 PM

oh damn. that excludes the experimental brushes

andybak•11/5/21, 8:47 PM

Yeah. I need to figure out how those values are calculated

andybak•11/5/21, 8:48 PM

I've got a nasty feeling that is lost in the sands of time. It must be derived from the brush script to some degree but I'd be guessing

andybak•11/5/21, 8:49 PM

@1pld @Tim A - I don't summon you from the magic lamp often - but how are brush weights calculated?

Tim A•11/5/21, 9:15 PM

Ha ha ha ha

Tim A•11/5/21, 9:15 PM

'calculated'

Tim A•11/5/21, 9:17 PM

bless your heart

Tim A•11/5/21, 9:18 PM

I don't know where the values originally came from. I seem to remember adjusting them a bit when we did the Quest port.

Tim A•11/5/21, 9:18 PM

I think they largely just reflect our best-guess estimate about how quickly they make your scene slow

andybak•11/5/21, 9:25 PM

Ha! Ok. That actually makes my job easier (slightly). I'll copy values from similar brushes. Back into the lamp, now. ;)

Thanks all for the deep dive into an attempt to answer these questions! I'll try track my FPS as I go and I can get some feedback with that too

Can you give us some examples of what you want to change?

Quality, capture duration, movement speed

Is this the "wobble" mode?

Aandybak Is this the "wobble" mode?

NLR•11/6/21, 7:04 PM

both modes

NNLR both modes

andybak•11/6/21, 7:05 PM

What are "both"? I lose track of what modes are available. There's about 4 in the experimental build and I rarely use the non-experimental builds.

Zandy•11/6/21, 7:23 PM

Is there a way to change out the skybox to transparent png since the camera will capture pngs already?

AncientWorlds•11/7/21, 5:22 AM

There's a wobble mode and a 5 second gif capture.
The 5 second gif capture makes a really nice walk through photobox, but quality is too low to be useful on active sketches
agree that all of these would be beneficial improvements
One of the other reasons I like the gif camera is that it reacts to audio, but doesn't record audio by default.
This is important for social media sharing, as I almost always listen to music while working.
Would be nice to have that as an option on the video camera as well

andybak•11/7/21, 1:10 PM

There's actually 4 modes defined:

andybak•11/7/21, 1:11 PM

But they are disabled in non-experimental builds. There's also keyboard shortcuts to adjust some of the parameters

andybak•11/7/21, 1:12 PM

there's also this:

andybak•11/7/21, 1:12 PM

which seems to be sub-modes for the circular gif?

andybak•11/7/21, 1:14 PM

Not sure why Quest can't do mp4 video but I'm tempted to allow it to capture frame sequences as an option and leave it up to the user to compile them into video, gif or whatever. The current gif mode should just be a quick convenience mode

mikeage•11/7/21, 1:19 PM

I don't recall if we have available on the Quest, but I think output a series of frames plus a bit of documentation listing common options like should be quite useful; it offers a lot more flexibility than writing compressed video, and can fit into any workflow. If we have specific requirements for certain formats, then we can look at offering quick presets too

mikeage•11/7/21, 1:20 PM

I guess we don't have ffmpeg:

andybak•11/7/21, 1:21 PM

I don't think android allows multiple executables in an apk? or at least they are clamping down on that kind of thing

andybak•11/7/21, 1:21 PM

i seem to remember that was the issue with LPGL code - you can to create a single signed binary

andybak•11/7/21, 1:22 PM

Although we could release a "companion app" that made it all user friendly - but something like that probably already exists

mikeage•11/7/21, 1:22 PM

I don't know. We can distribute other files, including executables, using an file (or possibly an , I think it's called), but I'm not an expert on exactly how that packaging works

andybak•11/7/21, 1:22 PM

got to be aware there's people who have a quest but don't own a PC or Mac or anything separate.

mikeage•11/7/21, 1:24 PM

Fair, but I feel like once we have an on screen keyboard and can name our sketches (and thus do things like foo.tilt -> foo_output/1/xxxx.png), it'll be much easier to output just images and have people put them together. It won't be sufficient for those with no computer... but I think for an MVP, it's definitely a higher priority than one more canned output format that may or may not align with a specific requirement

mikeage•11/7/21, 1:24 PM

Or maybe we can do images -> video as a hosted icosa service?

andybak•11/7/21, 1:25 PM

there must be a dll version of ffmpeg that we can call directly from C#? I wonder how ffmpeg is being called presently.

mikeage•11/7/21, 1:26 PM

Assets/Scripts/Rendering/FfmpegPipe.cs

andybak•11/7/21, 1:27 PM

hmmmm. ffmpeg must have a C API?

andybak•11/7/21, 1:27 PM

ah - we might hit GPL issues

mikeage•11/7/21, 1:28 PM

libavcodec is LGPL IIRC

andybak•11/7/21, 1:28 PM

and we're back to exactly what does "linking" mean.

mikeage•11/7/21, 1:28 PM

Or maybe dual licensed GPL/LGPL. BRB, googling

mikeage•11/7/21, 1:29 PM

Yep, dual licensed.
