This appears to be the same underlying issue as Saving Composition to Node Library does not update relative file paths or copy files.

If you first made (Loyalist )ConvocationGUI.vuo as a regular top-level composition, the Fetch Image nodes would have worked fine because they were referencing image files relative to that composition file (like ../../../../Desktop/LC Convocation VUO Master/Image Elements/GUI_Buttons/Zoom Increase.png). If you then changed it to a subcomposition, (Loyalist )ConvocationGUI.vuo would have been moved to your User Modules folder, and it would then be looking for image files relative to the new location of the composition file — so it would no longer be able to find them.

As a workaround, you can edit the values of your Fetch Image nodes' URL input ports, making them absolute paths instead of relative to the (sub)composition file. For example, change ../../../../Desktop/LC Convocation VUO Master/Image Elements/GUI_Buttons/Zoom Increase.png to ~/Desktop/LC Convocation VUO Master/Image Elements/GUI_Buttons/Zoom Increase.png. (The ~ is an abbreviation for /Users/[your username].)

This hasn't got much support in votes, but I think that given the relevance of various VR and 360 platforms (Oculus, FB, Youtube, Vimeo, etc)... it would be really cool to be able to have some stock support for this, if it could in fact be more heavily optimized with a specific node for it, than Alex's method. I suspect it could be.

Pathes with vuo.math.calculate don't work on case-sensitive file system


Vuo version: 

Fixed in Vuo version: 

OS version: 

  • OS X 10.11

How severely does this bug affect you?: 

●●●○ — It prevents me from completing a specific task with Vuo.

Steps causing the bug to occur: 

  1. Create new composition
  2. add vuo.math.calculation to the composition
  3. Run
  4. -> "There was a problem running the composition" error message, details "Node outdated or broken...check the Console application"
  5. -> Console application show error "Vuo Editor: VuoCompiler.cc:2077 getLinkerInputs() Warning: Could not locate dependency 'muParser'."

Have you found a workaround?: 

Avoid using vuo.math.calculate -module. Almost all equations I need can be done with combination of add, substract, multiply -modules, but I would also need modulo -operator.

Other notes: 

I think that this is so fundamental module that it have to work with most of people. So, there have to be some conflict with vuo and my system.

My guess is that problem could be that I have case sensitive file system, which is not the default option in osx (but still an option in normal osx install). Maybe muParser is called with wrong casing somewhere,..just a guess.

Images not displaying when using custom User Node in Library


Vuo version: 

OS version: 

  • macOS 10.12

How severely does this bug affect you?: 

●●●○ — It prevents me from completing a specific task with Vuo.

Steps causing the bug to occur: 

  1. Load Custom User Modules into VUO (Provided in Zip file)
  2. Launch Convocation Master (3360x1080) v1.1 composition
  3. Play Composition (No images are displayed?!?)
  4. Stop Composition
  5. Double Click custom user node (Loyalist )ConvocationGUIto open it in the editor
  6. Play Composition (Images show up now?!? Why?)

Have you found a workaround?: 

Not entirely and I'm not sure this issue is confined to the custom user nodes it's just that I can repeat it regularly there.

Other notes: 

I reported this already in the Discussions Forum but after further testing today I am quite certain this is a bug.

This project I'm working on is critical to our June 8&9 Convocation Ceremonies. I've been working on this project for quite some time, all my testing was working beautifully, only recently as I started putting the pieces of this project together are things falling apart. Previous years I've done this project using QC however the 2011 MacBook Pro laptop I had used for that is no longer stable and I don't have an alternative Mac with Lion installed that has the proper I/O ports for running the old composition so I have to make VUO work! Please help!

Thanks for responding.

Yes it is a 2013 MacPro with D500 GPU. I am currently testing the 1.2.6 build 4 Beta for this project to test the new XML nodes (I left that part out of my attachment as it appears to be working very well and others wouldn't be able to load those nodes yet). I'm not sure if this build contains the AMD fixes or not... @Jaymie???

If there is a fix I'm really hoping it arrives very soon.

Is there a way to have a fragment shader write to depth buffer?

That's basically it...

Is there a way to do this that I am overlooking, or if not, is there a possibly an existing patch that could be modified to write to the depth buffer?

I would like to make something in the fragment shader that depth tests against objects created with regular VUO node shapes and imported models.

edit: In QC, one could do this by writing to gl_FragDepth. I just remembered about the parabox node...I'll try and see if it works there.
