the upload isn't mine, but it's just titled incorrectly
it appears to be the conversion of the vmaterials for daz that was available on sharecg and not the vmaterials download (at least from the requirement for vmaterials itself)
Update to that, it seems to be a combination of vmaterials and the conversion based on the file size (~2 GB) perhaps @psygameboy can elaborate on whats included.
and yes the conversion is free on sharecg but it does require a signup.
Jess all the stuff here is free. I thought it could be helpful for someone. You can go to nvidia give them your email and wait for the download of v materials. Then go and download the converion stuff. After that go to share cg and make a registration. Then search for converted vMaterials.......or just take this pack and find all in one for Win and Mac.
