I finally looked at this again. I made a very simple model that uses a small QC file and a small mesh SMD file. I then made a copy of the files and changed how the material lines were written in the copied SMD file.


I compiled them, then decompiled them. For each example, Crowbar created the same $CDMaterials line and the same material lines in the SMD as they were in the original.

The test proves that the MDL file stores the material paths in different ways depending on how they appear in the given files and Crowbar is simply decompiling what it finds.

I realize that you think this is a bug with DMX files, but Crowbar knows nothing about DMX. Crowbar simply writes the QC and SMD files based on what is in the MDL file.

I am leaving this bug report open because I intend to redo (with some tweaking) what some older versions of Crowbar did with the material paths, so that $CDMaterials show all paths and no paths show in the SMD material lines.

Changelog:

=== General ===

• Added new tab, Preview, that looks and functions the same as View tab. This allows comparison between two different models and opening of two models in HLMV via Crowbar.
  This is intended to help in the workflow of previewing a model before decompiling it and later viewing a re-compiled version of it for comparison.

=== Decompile ===

• FIX: Crowbar 0.30, 0.32, and 0.33 skip physics meshes for MDL v44 and higher.
  
• FIX: Crowbar 0.33 does not create BMP files from MDL v10.
  
• FIX: MDL v44 QC file has $MaxEyeDeflection line, but should not.
  
• FIX: Selecting a MDL File or Folder that has too many characters shows exception error window.
  
• FIX: Decompiling v_rifle in "End of Days SCAR-L (Black) Replaces M16" addon [ http://l4d.gamebanana.com/skins/115197 ] creates NaN in one of the animation SMD files.
  This fix improves the decompiling of animations for MDL versions 44, 48, and 49.

=== Compile ===

• Added some new error messages, including two that relate to incorrect locations for studiomdl.exe and gameinfo.txt files.

=== Preview and View ===

• Added some new error messages, including two that relate to incorrect locations for studiomdl.exe and gameinfo.txt files.

=== Set Up Games ===

• Added a "Clone" button that when clicked will add a new game setup with same inputs, except for modified name, as the currently selected game setup.

Imagine if Crowbar actually were able to detect that mistake and then told you how to fix it?

Hint: It's a planned feature.

:)

Reported in group chat by Horrigan.

Crowbar version: 0.33

Steps Taken: Download this rifle addon[l4d.gamebanana.com]. Decompile.

Expected: Decompiled files with no NaN in them.

Issues: The animation SMD file, "helping_hand_retract_layer.smd", has NaN in several places and will cause a compile to error.

This line in the QC file is missing an end double-quote:
It should look like this:

Originally, I did not upload to GitHub because it was too much of a bother and I did not know how to use Git.

Presently, I am considering uploading the source code to GitHub, because I have at least a basic understanding of how to use Git.

Perhaps the "idle.smd" file has no animation data.

My guess is that the Blender Source Tools removes "problem" vertices from the VTA file. The "problem" vertices might be from Heavy being compiled in DMX format and some vertex animation info can not be decompiled to SMD format.

Your QC is missing the closing brace for $model.
Place a closing brace by itself on the line before $mostlyopaque line, like so:

I checked this by importing the reference SMD and then the test DMX into Blender via Blender Source Tools. Blender Source Tools lists 45 missing bones and all of them look like names of vertex animations rather than bone names.

This is not a bug with Crowbar.

Some possible causes of the problem you saw:
- The SDK scout files are simply not the same ones used to make the model used in-game.
- The test animation was not created the way you expected.
- SFM exported the test animation incorrectly.
