Thanks for the report!

It looks like there are error messages from other addons (Blender GIS, Extreme PBR, Align Tools), but I am not sure if they are related to the Alembic launch failure.

Would you be able to test the issue within a factory clean Blender environment? This test involves temporarily renaming your Blender userdata folder:

C:\Users\Guyml\AppData\Roaming\Blender Foundation\Blender\4.1

Instructions can be found here: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Addon-Installation-Troubleshooting#create-a-clean-installation-of-blender

Does the Alembic launch still fail in a factory environment? If so, what is the full message that is displayed?

GuyJan commented 1 month ago

Hi Guy,

I followed your instructions and create a clean version of blender 4.1, and opened the file:

"H:\Stoommachine\Corliss\3D_Model\Condenser&AirPump\AirPumpV2.blend", which was already baked, and launched Alembixc export.

I received following error message:

Blender 4.1.1 (hash e1743a0317bc built 2024-04-15 23:33:30)

Error: Cannot read file "H:\Stoommachine\Corliss\3D_Model\Condenser": No such file or directory

Blender quit

So I re-created the “condenser” directory, and launched Alembic export, an received following message:

Blender 4.1.1 (hash e1743a0317bc built 2024-04-15 23:33:30)

Error: Cannot read file "H:\Stoommachine\Corliss\3D_Model\Condenser": Permission denied

Blender quit

C:\Program Files\Blender Foundation\Blender 4.1>

Then I saved the file in the “condenser” directory, and the path became now:

"H:\Stoommachine\Corliss\3D_Model\Condenser\AirPumpV2.blend"

I adapted the cache directory to use the already baked cache:

The bake still worked correctly (FLIPMeshes/whitewater_bubble selected):

After relaunching Alembic export, I received following error message:

Blender 4.1.1 (hash e1743a0317bc built 2024-04-15 23:33:30)

Read blend: "H:\Stoommachine\Corliss\3D_Model\Condenser\AirPumpV2.blend"

         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

AttributeError: 'Scene' object has no attribute 'flip_fluid'

Blender quit

So I suspect the bug is nevertheless within the FlipFluids addon.

Why, as mentioned in the first error message, the path still points to a “Condenser” directory while its name was since long changed into “Condenser&AirPump” ??

Best regards,

Guy

Hi Guy,

I changed the name of the directory “Condenser&Airpump” into “Condenser_Airpump” and now the button “Launch Alembic Export” worked, and produced an xxx.abc file that perfectly could be imported into an other .blend file, although the materials were missing – bt that problem can be easily solved.

So the “&” character, although accepted by blender, is indigestible for FlipFluid or Alembic.

My problem is solved, even within my original blender-presets environment with all addons enabled.

However, for your info, herewith the error messages at the end of the run:

WARN (io.alembic): C:\Users\blender\git\blender-v410\blender.git\source\blender\io\alembic\exporter\abc_writer_abstract.cc:105 update_bounding_box: Bounding box is null!

Thanks for all of the troubleshooting! My apologies for the delayed response, I was away on holidays and am now back to development on a regular schedule.

I think we should be able to fix and avoid this issue. We have had a few similar bugs in the past related to special characters in filepaths.

GuyJan commented 3 weeks ago

Thanks you for your response.

I have however still a question: after importing the Alembic file, made by FlipFluids, into the final .blend file, the whitewater bubbles, foam etc. appeared to be only vertices, no mesh, so I still had to transform these into icospheres and apply the corresponding shaders. Is this normal?

Br,

Guy

Hi, that is normal and it is optimal for the Alembic whitewater to be mesh vertex data. The FLIP Fluids addon automatically sets up the whitewater vertices for rendering, but you will need to do this manually when it is an Alembic mesh. More info: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Alembic-Export-Support#rendering-alembic-whitewater

rlguy commented 2 days ago

A workaround to this issue has been added for the next FLIP Fluids version 1.8.2 (release date TBA).

The workaround will be applied only in the case that a Windows filepath contains an ampersand (&) in the filepath. At the moment, there are not any other known special characters that may cause this type of issue.
