Just a heads up. Nem and I finally got our VTF tools updated to include the 7.4 format from TF2. I know a lot of you were a bit frustrated by them not working properly before. Unfortunately Nem and I were busy with other things hence the delay.
Nem has update VTFLib, VTFEdit and the Photoshop plug-in on his site and I've updated the VTF Shell extensions on mine.
One new feature that we've added. We've utilised the new resource types to implement author metadata support. Basically within the VTF file you can now embed the authors name, contact details, texture version, the game/mod it was made for and a brief note. This might help with textures that get shared and not being able to tell who or where it came from. It's also good for mod's for tracking where their assets are coming from. You embed the info with VTFEdit and my shell extensions support it as properties so you can organise and sort by the metadata.
Anyway, enough rambling, heres the links:
3DS Max VTF plug-ins will be updated soon.
