Coding Released Scripts and Themes

Hi, I would like to share a Blender addon, “VHT tools for Blender”, available on VHT webpage.

This addon does not work with Blender 4.0 upwards.
This addon is made for Blender 3.x.

These tools will help a CG artists to work in VR using Cycle or EEVEE render engine and to create 3D stereoscopic 180 or 360 degree panoramic computer generated art images or videos for VR users.

For more informations read the “VHT tools for Blender - User Guide.pdf” from VHT webpage.

Demo use cases

For demo render samples go to VHT webpage.

This was a nice surprise. Great idea to use the VHT environment for more than just watching films!

I struggled to install it because I was trying to select the zip file (which is the common method) but your instructions say to select the .py file and indeed that worked. Excellent. Now off to have a play with it and will report back …

Unfortunately I can’t launch VHT from Blender. I’m getting this error:

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Program Files (x86)\\Steam\\steamapps\\libraryfolders.vdf'

To try and solve that, I edited the script line 1088 to point at my Steam folder where the libraryfolders.vdf is located (libraryfolders = r’Q:\Steam\steamapps\libraryfolders.vdf’)

But now I get this error:

Error: Python: Traceback (most recent call last):
  File "P:\Blender\Builds\Release\4.0\python\lib\subprocess.py", line 971, in __init__
    self._execute_child(args, executable, preexec_fn, close_fds,
  File "P:\Blender\Builds\Release\4.0\python\lib\subprocess.py", line 1456, in _execute_child
    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] The system cannot find the file specified

I should say that I’m using a virtual second monitor, as I don’t have a real one. It seems to work okay. I can select it in SteamVR and move my VR stereoscopic window there and maximise it. So I’m hoping it can work that way, but I don’t understand your script (I’m not much good at coding) so am not sure if that is relevant.

Perhaps you’d rather have a separate thread for troubleshooting, in which case perhaps you could create one and I’ll repost this there.

Is my fault, I forgot to add the following line
This addon does not work with Blender 4.0 upwards.
to this post.
This script is made for Blender 3.x.
I will create later another script for Blender 4.x

Yes ,it works with a virtual second monitor.
At page 5 from “VHT tools for Blender - User Guide.pdf”:
the second display can be a real, dummy or virtual; 2K or 4K native or custom.

Thanks for reporting these issues.

Try the new version.
It has a fix for Steam path error.
