My model aswell, i compiled it and opened in sfm and its invisible, and if i open it in the model viewer i get ,,error loading model``. What we should do?!

So I want to port a goldscr model to sfm. I did made the textures to vtf and vmt using gimp and vtf edit. I did edited the QC file with all that stuff and when I compile my model doesn't compile, I don't understand what is going on :(

So it got this error, I looked at the QC but nothing was wrong at all, I still have no idea how to fix this error.

I. Is that possible to keep all Blended sequences and NOT commenting them out/deleting them in the QC in a Goldscr model to Source/SFM/Gmod , can the blended sequences a little bit modified but kept them be still compiling in the QC?

II. If still NOT , is that possible to rewrite the blended sequences(in the QC ,ofc) into $animation ones , if I want to keep the blended sequences from a Goldscr model intact in Source/SFM/Gmod?

+BONUS!
III. If I have different skins for a retextured GoldScr model , adding the the skins with $texturegroup for the skins in the QC.

■ While compiling it won't give any errors, if i add different skins with $texturegroup in the QC ?

IV. How do the $animation work for a Goldscr model ported into Gmod and SFM ?
