I think it's the last error preventing the build though?

Cchard I think I grabbed from here https://github.com/icosa-gallery/open-brush/pull/200

andybak•11/29/21, 7:44 PM

btw that PR is currently buggy. I pushed a fix this morning that broke scene merging completely. will fix tomorrow

andybak•11/29/21, 7:45 PM

Can't help much on the build stuff as I never build locally. I rely on @mikeage 's nice CI cloud build

s_haha_n•12/2/21, 10:09 PM

is there a way to adjust for the brightness in recordings? so it's the same as snapshots?

mikesky•12/2/21, 10:10 PM

hmmm, this looks like a colour space issue possibly?

s_haha_n•12/2/21, 10:17 PM

in the past i've exported to unity and recorded that way, but always wondered if this issue could be solved, i think it "started" when i used quest+link and set the visual quality settings to max and then the video recorder just doesn't capture at that setting? also wondering if it's a quest+link only thing?

s_haha_n•12/2/21, 10:18 PM

i'm still messing with my config but not sure if some setting here could help? *just noticed the video resolution not supported. can those 3d error panels that fall on startup be viewed elsewhere?

AncientWorlds•12/3/21, 2:51 AM

I think you hit some limits with the quest itself, since it's got a limited processor on-board,
so presumably affects video recording. I can't remember if it records paths on the quest although I assume it does (it's a .usd file)
(I usually use desktop, so my memory of the interface specifics is a bit vague),
If so, there's a command line tool to record at higher resolution from the computer itself that can rerun the path and re-output the video file.
Not sure about the lighting mismatch.
You should be able to brighten it by moving the slider on the right side of the lighting panel up a ways, if the option is available.
Wouldn't solve the mismatch, but as a temporary measure should give your scenes more light in general, resulting in lighter colors on the output

sorry, before this, I have an error when I import sdk : "Multiple precompiled assemblies with the same name Newtonsoft.Json.dll included or the current platform. Only one assembly with the same name is allowed per platform. (C:/Users/Gildas/Documents/Unity/ago9/Library/PackageCache/com.unity.nuget.newtonsoft-json@2.0.0/Runtime/Newtonsoft.Json.dll)" so I close unity project and reopen it, and this error disapear, then i import the model

Video export using the usd and bat files is described here.
https://docs.openbrush.app/user-guide/exporting-videos
Camera paths are automatically generated when filming, at least on the pc side (need to open my quest again and look)
The video pathing feature, where available, can also be set up directly.
Takes a bit of practice to use it well, but it's a really nice system that's quite powerful.
Extremely useful for scenes that are too large to easily walk through or reach different angles.

If I have a horse model in unity, and I want the horse to ‘transform’ into a cube, how do I do this? I think I’ve seen stuff about this in machine learning art? Where you take 2 forms and the algorithm finds the midpoints between them? How could I do this in playmaker please? Thank you!!

Ozymandias•12/5/21, 3:47 PM

sorry have seen this sort of art around here so was wondering if anyone had suggestions re what to google! Thanks a lot!

andybak•12/5/21, 3:54 PM

Not sure if Playmaker can do that. You'd need to do it in C#

andybak•12/5/21, 3:54 PM

(or a shader - but coding either way)

andybak•12/5/21, 3:54 PM

Or - do it in Blender

Yeah that’s a non trivial problem haha

i just thought it was thematically related

Ozymandias•12/5/21, 3:58 PM

was considering posting it in off-topic

andybak•12/5/21, 3:59 PM

ah. thought that was meant to illustrate the morphing you wanted to do

andybak•12/5/21, 3:59 PM

anyway - it's a hard problem. especially for two meshes with different vertex counts/topology etc

Ozymandias•12/5/21, 3:59 PM

thanks will look into the mesh deformer, sounds like it would do the trick, just not altogether familiar with the github processes etc. so have a learning curve to scale lol thanks so much!

andybak•12/5/21, 3:59 PM

personally - i'd use the VFX Graph and fake it with particles

chardOP•12/6/21, 8:46 AM

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.

andybak•12/6/21, 8:56 AM

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.

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