It came with a copy of 3D World (Cinema 4D CE that is). I did the registration, got hooked (I think it was the lighting that really got me), and am now running R9 core with Advanced Render 2. I must admit, I would like to see bryce's terrain lab brought into C4D as well as some aspect of the procedural materials.

Pass no temptation lightly by, for one never knows when it may pass again!
