2.78 Blender Locks on Loading

27 June 2017 18:56
Setttings/File/Scripts: \\blend4web_ce
Full Path to polib.py: \\blend4web_ce\addons\blend4web\lib\polib.py
Blend4web version: blend4web_ce_16_12_1
Blender Ver: 2.78 a, b, c.
Windows Version: 10
Computer: Dell T3610

Blender locks if restarted during a session of Windows. Blender does not lock when first started. Exiting Blender normally, and not rebooting PC, and then reloading will cause Blender to lock. If you rename the polib.py to polib.bak, Blender will load without locking during entire session of Windows.

After locking, Task Manager shows CPU use 0%.

Renaming polib.bak back to polib.py and the rebooting PC will allow you to run/load Blender first time during that session. Blender will lock if exited and reloaded.

The problem appears to have started with 2.78 of Blender and build 15 of Blend4web.

Hi, nwhiting,
I think the first thing to try is to make sure you are running the latest version of Blend4Web. Currently 17.04.1.
And make sure your file path to the SDK is correct. It should look something like this in User Preferances > File > Scripts.
C:\blend4web_ce\
If that doesn't work I would start suspecting a problem with the Blender install.

Hello! And welcome to our forum!

Blender locks if restarted during a session of Windows. Blender does not lock when first started. Exiting Blender normally, and not rebooting PC, and then reloading will cause Blender to lock. If you rename the polib.py to polib.bak, Blender will load without locking during entire session of Windows.

This is strange.

The problem appears to have started with 2.78 of Blender and build 15 of Blend4web.

The corrent behavior of B4W 15 is not guaranteed for Blender 2.78 (check compatibility table).

But pair 16.02 and 2.78 should work. First, please, try what Will suggested and ensure that previous version of B4W has been removed (follow the documentation).
