I guess it needs to be repeated. Wartech was shut down for a TOS violation not anything to do with his products or alleged copyright infringement. This is from the staff at Renderosity posted above and in the other thread.

What I take away from Renderosity's statements goes like this...

They (Renderosity) affirm that the models that Wartech was selling here are his own and do not infringe on anyother's copyright. At no point did they tell buyers to stop using the models from the seller.

This is very poignant in that they are aware of alleged copyright issues but have not directed buyers to take action.

So...as a commercial artist, I am going to use WarTech's models that I purchased in good faith with the understanding that Renderosity has now fully shouldered any liability from the use of those models.

If I am mistaken in Renderosity affirming that these models can be used they are free to contact me (hopefully soon as I have several pieces that are due to be sold) and clarify the situation.
