Welcome to week2. As usual time is flying fast & we had our pitch presentions this week.  The modelling is well underway & this week I got my hands onto Zbrush 4R8. I have to admit I was very excited to see some of the additions in this version. The gizmo for the transpose is very handy for small changes & the fact that the original transpose tool still remains for making bigger changes like posing etc is very convenient.

One new addition is the Live Boolean feature. I haven’t really used it so far but I can already see some of the areas I plan to try using them on like the hair. Just a gist of what I have been able to understand about this feature so far.

We always had the Boolean features available to add, subtract or give the intersect result while modelling. But we needed to do this along with dynamesh & it was always very hard to envision the end result of the action until we had done the entire process. Now with this live Boolean feature, it renders the end result on the fly giving us a lot of flexibility to see exactly the result we will be getting so we can modify it until it is just perfect. We are also able to use the various brushes to make changes on the Boolean subtools while live Boolean is on. So any modifications required at that time is very easy to do on the fly as we go along. Once we have the required result we can just create a new mesh by clicking on the “Make Boolean Mesh” Button. This results in it creating a new geometry of the result which not only stores all the original mesh geometry at the level of density it was but also all the original polypaint data. The only areas where it is remeshed is where the Boolean was applied.


Eg: Lets take the frog example from Joseph’s Zclassroom lesson.

Here is an example of a very high dynamesh frog model with 2 very high dynamesh models of rocks.

He places the rocks into the frog model to try to achieve a chiseled look.


But with turning the Live Boolean feature on it shows the end result render real time to help with better placement & sizing.

Once the desired result is achieved & the new mesh is created using the make Boolean mesh button, the end result has new remeshed geometry only in the Boolean areas & all polypaint data still stored.
