I've imported a model into Max that has some textures (http://imgur.com/RKPa4cN) already assigned to it to it. The problem is that the .VMT materials are being exported, but the .VTF textures aren't. (http://imgur.com/viiMzt7) - I see no mention of them after I press 'Export VTFs'. This results in my Source Filmmaker model coming with the default grey diffuse material. (http://imgur.com/kt5FPP6) Normally if it doesn't have a material attached to it, it'll be purple/black checkers - which means the material is being added, but the texture isn't. Therein lies my problem.
I'm not sure how to 'add' them to the export options. I've tried using the 'Pick Material from Object' button in the Material Editor, which grabs the multi-material associated with the object (in the second picture on the right), but that isn't really doing anything. I'm not sure what I need to do, as I'm relatively new to 3ds. I'd appreciate any help.
Fixed the issue - my texture files were apparently incompatible, as they were .png and apparently .tga is required! Everything works fine now. Is there any way to keep it as .png, because most of the files I'm extracting contain textures which are .png, so converting them in bulk can be a pain.
Glad you figured it out.
Unless vtex.exe accepts PNG now, then it's not going to be worth it due to the hit to the texture lookup times. Historically, vtexe.exe (which is the texture compiler that converts TGA to VTF) has only accepted TGA, PSD and PFM. WW Pro uses a separate VTF compiler and toolset, does allow any kind of texture.
Awesome, thanks for the reply - so if I purchase Wall Worm Pro I should be able to export .png texture files to Source Filmmaker as well?
Yes, WW Pro can natively export any texture that can be loaded into Max, including procedural textures and Substances, etc.
