I created this in C4D and Photoshop. I modeled the knife in C4D and textured it in BodyPaint 3D then created all the blood in photoshop. This was about 7 hours of work. Still wrapping my head around BodyPaint.
Here’s a photo I compositied for a client. I created most of the fireball in Cinema 4D using Turbulence FD. Then I blended several C4D renders together in photoshop along with one stock photo of fire. Click on the image to see all the detail.
