It is probably the same issue as with the model files; the material and texture files must be placed in the correct folders. There are about 5 or 6 things that need to be correct, as indicated in this video tutorial: https://www.youtube.com/watch?v=ilqhtS5wqsA

CAUSE of the problem:
Source Filmmaker's HLMV requires the model files be within one of its gameinfo.txt SearchPaths, for example, your model files would have to be placed into "D:\Steam\steamapps\common\SourceFilmmaker\game\usermod\models\nuparu".

One option to try -- you could have Crowbar skip the moving of the compiled files after the compile (as indicated near the bottom of the log) by setting the Compile "Output to" option from "Work folder" to 'Game's "models" folder'.

Another option to try (and this is what I usually do to keep my game folders clean) is the "Use in View" button at the bottom of the Compile tab, After a compile, this button allows you to quickly select the compiled model for Crowbar's View tab. Within the View tab, click the "View as Replacement" button. This will open up the selected model in the selected game's HLMV. Crowbar behind the scenes creates a crowbar folder in Source Filmmaker files, adds that folder to its gameinfo.txt SearchPaths, and copies the model files to the correct subfolder within the crowbar folder. After HLMV closes, Crowbar reverts the changes.

The link works now. I will check out the model.

The Google Drive link shows "Access Denied" web page, so I can not download the model to check it.

Make sure to use the HLMV from the same game as the model compiler, in this case, Source Filmmaker.

I just downloaded and decompiled that model, and it worked just fine.

Maybe restarting the PC would help.

Link me the model so I can debug this.

The count of materials comes from all the different materials listed in the mesh SMD or DMX files plus any materials listed in texturegroups 2 and up (i.e. not the first one, which should represent those found in the SMD or DMX mesh files).

Note this is not a bug with Crowbar nor with the model compiler found in the game that Crowbar calls. This is simply a misunderstanding of how materials are used and counted.

Hiya, Paynamia! Thanks for your excellent bug report.

Would you believe I already had this bug to fix on my ToDo list? I tried to do exactly what you tried and have considered several methods to handle this situation. Have not decided which method yet. I have wanted Crowbar to handle packing multi-file VPK packages for a while now.

I have recently been working on the next release of Crowbar, so I will try to fix this for the next release.

The box under the Publish button is a quota, not a progress bar.

The Publish tool in Crowbar 0.71 (latest at time of this post) does not have a progress bar. There are progress messages within the log. A progress bar might be added later.
