Well I know that it needs a vmt file but I thought that The texture would be exported somehow from the smd file. :/
Or how do I get the texture out from blender in case I decide to design my models texture with it since it's probably easier to do that.

Hey,
Not sure how often this was posted yet but yeah I have no idea on how to solve it and when trying to find anything there are only old posts and nothing has helped so far.
So I am trying to make my own models and I tried to add some simple things for my gmod map I'm working on. I created some candles, A beam structur I premade in the hammer.exe/source SDK and imported into blender to then export to create a model. So far so good. Now I decided to try to add an orange texture to the pumpkin I made and all I can manage is to get the same missing pink and black texture.

So I followed this tutorial. https://www.youtube.com/watch?v=Dam1fy5Bi7A
I know it's pretty old but it gave me most of the tools I needed to get the first models into my map. So I did as he did. I named everything in blender (version 2.81.16) the same. The model is called Pumpkin_1 and so are the project data (the green triangle) and the materials. Then I export via the Blender Source Tool as SMD. Export Path = a path onto my USB-Stick but no spaces used. The Engine Path is "G:\Steam\steamapps\common\GarrysMod\bin\" as I use that as my steam game library. Target Engine was set to source and that is all. So when I export I get a nice Pumpkin_1.SMD file which then gets a qc file from me with the following text inside.

$modelname "Varmints_Models/Pumpkin_1.mdl"
$model "Body" "Pumpkin_1.smd"

$staticprop
$cdmaterials "models/Varmints_Models/"
$surfaceprop "Pumpkin_1"

$sequence "idle" "Pumpkin_1.smd"
$collisionmodel "Pumpkin_1.smd" { $concave }

That is basically the same as in the video.

Then I move the SMD file + QC file onto the Studiomdl.bat which was also created due to the video and contains the following text.

Then it opens a window, has a lot of "Warning: Model has 2-dimensional geometry (less than 0.500 inches thick on any axis" and then it gets this text.

So now that it is done I also try to check it with the hlmv.exe inside the gmod bin folder but there and of course also inside the map editor it only shows me a pink and black pumpkin. :C

The error message in hlmv I get when checking in the model section is

Author původně napsal:

*** ERROR *** Model attempted to load one or more VMTs it can't find.

So now after all my search I came to nothing useful and I am ready to take any help I can get to get this problem solved.

Btw using Windows 10 Pro in case that this is of any relevance.
Thank you in advance for your help.
