Is there any way of exporting the MDL files out of the model viewer folder? I have a 3DS max importer for MDL files but I cannot find that folder anywhere but the model viewer, and it won't let me take them out.
you need GCFScape(google it) to open up the .GCFs and extract the textures - which will be in .vmt and .vtf format. Then download HL2 Compile Toolkit(at the top of the forum) and use the 'VTF to TGA' feature to convert the VTFs to TGAs.
and can you please direct me to where you got this MDL Importer
