I finally managed to work out what I was doing wrong / missing. I did not activate the size in the curve modifiers.
Thank you all for your help.
I do have another question! I am going to end up with a ton of sub-tools when my character is complete. I wish there was a way to organize them better? Similar to Adobe Photoshop. I like how Photoshop let’s you make folders. Does ZBrush let you make folders? What I find annoying, is when I am done with my character’s hair there will be a sub-tool for each tube I make. Kind of redundant?
Any suggestion are always welcome! Thanks for giving a newbie patience!
