i understand, clear as a day !
As this company is no more, people colected their textures and put them on rapidshare, its just a faster way to get them all...internet is full of their links and they are not banned anywhere. This package of textures will help many users of octane to get better renderings.
I really checked on internet and found answer that these textures are FREE !
I dont think that i break law if i download all their textures, and upload them to RS or what ever.
I can bet that you will NOT get any warrnig if you made first link availble !
But anyone can goolge it anyway
Have a good time !
