Crowbar version:
0.71

Steps Taken:
1) Extracted tf2_misc_dir.vpk/models/player/heavy.mdl via the Unpack tab (also tried with GCFScape, same steps and results);

a) Files unpacked:
heavy.dx80.vtx
heavy.dx90.vtx
heavy.mdl
heavy.phy
heavy.sw.vtx
heavy.vvd

2) Decompiled the model ( https://i.imgur.com/jdt7JLc.png );

3) Recompiled the same model with 0 changes ( https://i.imgur.com/IbLYZTt.png );

Expected:
The heavy.mdl model should have no changes whatsoever to the default one found in the game's .vpk, or at least very few unnoticeable differences.

Issues:
The main issue I am having is that recompiling the model via Crowbar will make certain cosmetics clip in-game, but for whatever reason, this is not an issue on Half-Life Model Viewer.

There is some very minor lighting issues when viewing on HLMV, but other than that, the model is basically identical.

But in-game, a multide of Heavy cosmetics (mostly shirt cosmetics) will clip on his vest area.

It's hard to know if this is a bug with TF2 or Crowbar.

The reason I'm trying this is because I was having the same issue with a MODIFIED heavy.mdl file. After multiple attempts trying to fix the issue, I went to try if I decompiled and recompiled the default model with 0 changes would still give me the issue, and noticed that was the case.

* I know I could just load heavy.mdl directly via the (Steam) Load Model, but I loaded from the mod's folder anyway. The previous album screenshots were done before the mod had its folder on custom.

Samples:

Additional Info:
I have recently reset my TF2 settings to troubleshoot/report this issue. My TF2 is basically nearly full vanilla, from a fresh reinstall (and no Steam Cloud integration being on). There is not a single cvar saved that modifies the model in some capacity, and if it did, issues with the default model without recompiling should already be noticeable.

This happens with other cosmetics, but I used the Heavy Lifter as it has no problems in rendering in HLMV (HLMV has an issue where it can't properly render hlp_bones, so I had to choose a cosmetic that didn't had any), though, even in cosmetics that has hlp_bones, it shows issues in-game.

I also tried with a custom folder with absolutely nothing inside, with the only exception being the recompiled default model... same results.

I sent my mod to my friend, to see if the issue would happen on his TF2, and yes, the same thing happens on his end.

I downloaded a mod from 2 years ago, on Gamebanana, that replaces the Heavy model, and the same issue applies.

Wow, that's great to hear! Thank you for your hard work on Crowbar, it's amazing!

You're using 0.29, correct? Try 0.33; that's the one I used and didn't receive any problems aside from what I described with Heavy.

I'll try it later, it has been months I did my last attempt on this.

Though, the Heavy was the one that I most wanted to edit :/

Don't mean to necro, but I just remembered this post while I was fiddling with things. It seems like Heavy's the only one affected by this nonsense and I think it has something to do with the .vta file. I actually just fixed the problem by importing Heavy's reference model in Blender, then the .vta, then exported both and recompiled with the new .vta file.

Nope, every class gets affected. I once downloaded a mod that disabled certain bodygroups (so the author had to compile the player models again). Everyone had their eyes bigger, and there were some texture issues with Demoman (texture stretch) and Scout (incorrect colors for the BLU hat), and maybe for the others which I haven't noticed.

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.

I'm not sure if I remember, but I think I tried decompiling and compiling without opening the files on Blender, and I got the same results.

Yep, not sure why the textures mess up too. I've tried once the $upaxis technique, but it didn't worked well.

It has been about a month I've tried this, so I don't remember everything I did.

Steps Taken:
1) Decompiled heavy.mdl;
2) Recompiled heavy.mdl.
Expected:
1) Correctly-recompiled model.
Issues:
1) Eyelides messed up and messy textures.
Operating System:
Windows 10 (64-bits)

_________________________________________

I've seen some threads about compilation of TF2 Player Models, but I decided to create another one with more details.

I'm trying to compile "heavy.mdl" file. If I try compiling it without any changes, this line is appear:

ERROR: e:\users\gabriel\desktop\decompiled 0.29\heavy.qc(161): - Unknown replace model 'heavy_body1_model1'

Deleting this (and the other from the LODs) causes nothing to the model, and after doing this, my model is compiled. However, the eyelids are a bit messed up (way too open) and there's some messed up textures:

(Texture issues: On the back and on white/red shirt)

Strangely, when adjusting the Flex settings, I noticed that, when pressing Random, One or Zero, the facial flex "animates" until going on that position, which doesn't happen on the original model.

I'm using the latest version (tested with 0.29 too). And I'm using a Windows 10 (64-bits).

On older versions of Crowbar, the $Neutral facial flex never worked, you had to remove that line in order to work. My theory is that the Neutral facial flex is not being compiled correctly, causing this "Googly" eyes to show up instead.

Thanks.

Yea, it fixed on the 0.29 version. Thanks.

Not for me, the "bug" still persists. This is how the .qc file looks like after decompiling:

// Created by Crowbar 0.19.0.0

$modelname "weapons/c_models/c_tw_eagle/c_tw_eagle.mdl"

$bodygroup "body"
{
studio "c_tw_eagle_reference.smd"
}

$lod 15
{
replacemodel "c_tw_eagle_reference.smd" "c_tw_eagle_c_tw_eagle_lod1.smd"
}
$lod 30
{
replacemodel "c_tw_eagle_reference.smd" "c_tw_eagle_c_tw_eagle_lod2.smd"
}


$surfaceprop "plastic"

$contents "solid"





$sequence "ref" "c_tw_eagle_anims\ref.smd" {
fps 30
}

$collisionmodel "c_tw_eagle_physics.smd"
{
$mass 4.2
$inertia 1
$damping 0
$rotdamping 0

}

I'm using a very old version, so I'll try updating it.

Pretty much what the title says. After I decompile a .mdl file, the $cdmaterials doesn't show up, and if I compile it again, it will have missing textures on HLMV or TF2. This doesn't happen with all models. These are the ones (that I tested, may not the only ones) that the $cdmaterials didn't show up:

Freedom Staff (c_tw_eagle.mdl)
Grappling Hook (c_grappling_hook.mdl)
Grappling Hook Projectile (c_grapple_proj.mdl)

I've tried just now decompiling a model that had no problems on the past and it was all ok, the $cdmaterials was showing up just fine. The model I've tried was for the Aviator Assassin (short2014_deadhead.mdl).

I'm able to just add the missing $cdmaterials and the path where the .vmt to fix it, though. That's what I did for the Grappling Hook and its projectile.

Thanks.
