The only thing you need to get this tutorial is to buy the 29th issue of 3DArtist and you will find the training on the DVD. The tutorial itself is about rendering and presentation of artwork did in Zbrush. The new rendering features of Zbrush 4 are now on a very high level and for a high quality render you don’t need to use any other 3D software. The course covers several topics like ambient occlusion rendering, adding subsurface scattering effects to our ZBrush models, rendering transparent refractive surfaces, rendering our ZBrush artwork into multiple passes for compositing purposes.
Chapters covered in training:
· Introduction and project overview
· Working with BPR shadows in ZBrush
· Rendering ambient occlusion in Zbrush
· Rendering refractive transparency in Zbrush
· Using the Fresnel Overlay material in Zbrush
· Rendering subsurface scattering in Zbrush
