Sculpting a Detailed Rock Asset in ZBrush

One of the most common models that you will have to model if you are doing architectural visualizations, and especially if you are doing assets for environments for the gaming industry is creating a model of a detailed rock or cliff formation. Well once you get to that point you will quickly come to a realization that even though at first glance it looks and sounds really simple, in reality rocks can provide a bit of a challenge and especially if you have never done it before. Well in today’s post i decided to tackle this issue and show you how you can create a fairly detailed rock in ZBrush, then make a low poly model of that and bake out normal maps and AO maps that you can use as a mask. To make it easier to follow i divided this into two videos so it’s easier to understand.

In the first video we will start with a little intro and a general overview of what kinds of a rocks we can see after which we will jump straight in ZBrush. We will use Dynamesh to get the general form, and then from there we will work with the Trim selection, the Trim Dynamic brushes as well as the Trim Smooth edges brush. After this we will take a look at the noise maker option for adding general noise on your model and we will finish up the fist stage of the rock. So if this sounds interesting check out the first part of the video.

In the second video we will continue from the same place where we left off in the fist one, and the very first thing we will do is get out of Dynamesh and Remesh our rock. This is where the “Holy Trinity” rule of Duplicate/Divide/Project will come into play in order to help us get all the details from the Dynamesh model onto the new ZRemeshed model. After all this we will also see how we can use some custom brushes to add in some details on the rock and finish it up. Then in the end we will use UV Master plugin for a quick UV unwrap and we will use Substance Painter to do a quick bake of the maps. But enough with the explanation, go ahead and check out the video for yourself.

After watching those two videos you should have a better understanding of what it takes to create a Rock asset that you can use in your Visualization projects as well as use it as a game asset. To be perfectly honest i wanted to make this video first so i have a base on which i can reference for a future video that i want to make that will cover many of the things covered here but create something more “cool”. But for now this will be all, and like always if you enjoyed the videos and you learned something new then share the post around so it can reach more people.

Creating a Base Armature for sculpting in ZBrush

Here we are back with another post about ZBrush. Today’s topic is a very simple concept and that is creating a base armature on which you can then continue sculpting. Main difference in working with traditional modeling software VS sculpting is that when you are working on a sculpt you have much more freedom to tweak your model as you aren’t constrained by technical issues. Another thing is that it’s a much faster way of making a model and at the same time bringing your concept to life. Well in today’s post we will see how we can build a base in Zbrush on which we can then proceed to continue sculpting.

In the first part we will start with a short explanation on what are ZSpheres and how to use them to get the base that we want to construct. In this video you will learn the basics on working with ZSpheres and how to control the detail level through the adaptive mesh. There really isn’t too much to explain as the video is pretty self explanatory so go ahead and check it out.

In the second one we will continue and expand on working with ZSpheres by adding in how to work with ZSketch and explain the main difference between it and ZSphere. You will also see how you can combine the results that you can get from ZSpheres and ZSketches into one subtool. Again it’s a short and self explanatory video so check it out.

Ok so if you’ve seen the videos you now probably have a better understanding on how quick and easy it is to get a basic armature shape for your prototyping stage. All in all as i have said multiple times in the past, ZBrush is an amazing piece of software that it would be great to have in your arsenal of skills.

That would be it for today and if you enjoyed this post then share, like and comment on it so it can reach more people.
