I’ve used zbrush 2 to make a face and mess around, and then I recently just got back into zbrush and I’m working on this two headed deer that trevor brown painted. Although I’d like to make it look a bit more realistic compaired to the original illustration. Here are a few screen shots of the work so far.
I’m thinking about restarting but if it’ll be faster to just edit this then that would be great!
Yeah i hate zspheres. They hardly ever do what i want them to do. For correcting the curve on the nose you can press W E or R and then hold down control to mask off an area, now you can move or rotate what hasnt been masked with the W E or R buttons selected. That would be the easiest for big alterations then you can go in there and do the fine tuning.
In regards to learning Zbrush before Maya for familiarity, Maya is completely different program with little to no reference to Zbrush besides the W E or R buttons lol. So learn it when ever you want.
Your best bet is to go to ZClassroom and you will find all the information you need for basic learning. ZSpheres just give you a basic shape to start from. How to add eyes and so forth are covered in the basic tutorials and the help files for ZBrush are excellent.
