ZBrush Usage Questions
#1

Just for your information, I am new to the world of 3d graphics. I have only been using ZBrush4 for 1 and a half weeks. I made this model of a T-Rex and everything seemed great till I wanted to start detailing.

Even though I am detailing at what I perceive to be a high subdivision level, The textures are coming out kinda jagged with the fine mesh able to be seen. PLZ note, I accidently deleted a lower subdiv or two but I think that the texturing you see was done at around subdiv level 6. It has a total active point count of around 8.5 million points. Ok. So that sounds like a hell of a lot of points to me. So my QUESTION. How can I give my model a smooth finish without any jaggies? Would it be ridiculous to sub divide it again as i have a suspicion it quadruples the point count meaning I would have 30 million + active points on my model. Or is there some other way i can smooth the damn thing or texture more effectively?

PLZ HELP ME!!! I have looked for an answer for sooooo long. I know I’m a noob so plz bear with me but I understand ZBrush well enough to understand the answers that you give regardless of complexity. BTW,I modeled the basic shape with Z-spheres then continually subdivided the mesh and built up detail on each one. Is this the wrong way to go about sculpting? Do i have to work my model up in sections? ANY HELP WOULD BE APPRECIATED. If the answer is to subdivide the mesh further then thankyou. I will be very happy. The reason I havent done that is bcoz my computer is crap. 2 gigs or RAM BAD to be exact.But i will upgrade my comp and load on windows 7 and run 64 bit etc etc to solve that.

Thankyou for reading this long winded plea, ANY HELP WILL BE APPRECIATED.PLZ note the model isn’t actually finished coz I’m putting it to the side until i can get an answer to this.

I´m not an expert but I think you should retopo the model and put higher mesh density to the parts that need details (head, feet…) and lower density to other parts (back, stomach…). That should help.

Actually I discovered the main root of the problem. After much messing with all the menus, I realized that my DSmooth tolerance under my display settings was set at 0. Upon boosting it to the highest my model became perfectly smooth. However, thank you for the advice. I’m definitely gonna add higher mesh density especially to the head where the problem was worst. :+1: :+1:

yeah retopology with more detail in key areas is the best idea.

with the current model, you could turn off quick mode for renders, and possibly turn the smooth up in the display properties to get rid of your ‘jaggies’

And you could texture with projection master rather than polypaint, which isn’t mesh dependent.
