The model appeared to have too many vertices. What is the max vertices for a model again?

This is strange. When the model was decompiled, multiple SMDs were created as well as VTAs. The model also appears to be divided up within all of the SMDs.

Yeah. The Basis Shape Key is selected, and all of the flexes are zeroed. I still don't understand what you were getting at with the doubling, like how would that cause an issue?

This is my QC. It is a very simple QC, body.dmx contains the whole model

$CD "D:\Desktop 12-20-19\Folders\Blender\Blender Exports\SFM Exports\Huck Rig Test"

$modelname "boomerang_from_cartoon_network\huckleberry_hound\rig_test\huck_rig_test.mdl"

$body "Body" "huck.dmx"

$mostlyopaque
$ambientboost

$cdmaterials "models\boomerang_from_cartoon_network\huckleberry_hound"

$sequence "idle" "huck.dmx" {
fps 1
}

It is a DMX. There were non manifold edges or vertexes, but when I removed them, the model still had distorted flexes in HLMV. A part of the the head was duplicated, before any flexes were made, in order to have black textured faces within the head so that when the mouth is opened, black can be seen.

I have Shape Keys on a model, in Blender, that work properly with no distortion. However, when I export a .dmx, of my model, and compile with Crowbar, I get this distorted result, in HLMV and SFM, as shown in my video below. In the video, the same flex is demonstrated in Blender and in HLMV as this distortion also occurs similarly on other flexes. Also, if I import the exported .dmx back into Blender, the flexes appear to be just fine.

I know the issue is my Armature as when I export without it, it works fine. So, now I need to take a look into the Armature, but I am not sure what would be wrong with it.

So, I have been working with a character, for a survivor mod, in Blender, and the model has always exported properly as a SMD, but when I export as a DMX, I get a Traceback error. I could just use the SMD, but I think I need to use DMX so that I can easily have my model's Shape Keys work in-game as I know SMDs require the coding of a VTA in the qc, which I am not sure how to do.

For a model that I am currently porting to SFM from Blender, I need to have the "Doubled Sided" normals checkbox checked in order to avoid ambient occlusion errors in SFM. However, the double sided normals are not applied to the model as the normals will not be doubled sided on the exported DMX files. Is there a way to apply double sided normals to a model so that the normals are double sided on my file that is exported with Blender Source Tools?

I have a model with two materials assigned to it. If I export it as DMX and then import it back into Blender, it only has the first material.
