Zbrush - Week 7:
In this blog I will be talking about Dynamesh vs ZRemesher and how we can use them for different types of models. I will also show the model that I made in class so that we could understand how ZRemesher works on a model that we have made.
To get a reference image in your scene you need to go to Draw Menu > The icon in the menu in the top left > Either choose front and back or up and down > Map 1 > Import your image > Select it and then it adds it into the scene.
We were asked to create a hard surface model and I chose to a shoulder pad for a piece of armour. I chose quite a simple shape which I was able to complete the base for however I was struggling to get the spikes to look right and I tried different methods such as duplicate the model however I felt it didn't look right so I tried sculpting it on instead however I was struggling to make it look right from both the front and the back.

This is the base sculpt that I was quite happy with for the shoulder armour piece. I found it quite easy to do as I used the move tool and smoothed it out for the shape.
I tried sculpting the spikes however I couldn't get them to look the way I wanted however we just needed something that we could use to learn what ZRemesher does so I wasn't too worried about it not looking as good as it could.
We used polygroups to split up the model into different sections and learned that we could still keep the polygroups after using ZRemesher if you click keepgroups on which I thought would be useful in the future.
When I used ZRemesher I found that it was splitting the spikes I made into two seperate spikes instead of just one which I didn't like which I would have to watch out for in the future however I could see that the ZRemesher changed the topology of the model to be made up of quads. Its a useful tool to know so that when I am making more complex models in the future I can use it to help with getting better topology without spending a lot of time on retopology.
Dynamesh won't give you clean topology and is better suited for quickly fixing topology however ZRemesher is better for when you need nice clean quads for a model. Dynamesh is better to be used for organic modelling however ZRemesher is better for hard surface modelling however both have their strengths and weakness so sometimes one is a better option than the other, it just depends on the model. Using Dynamesh can be useful if you need to create a separate part of the model with the IMM tool using Dynamesh will connect it to the original mesh after you finish so that you don't about affecting the original when modelling it.
To use ZRemesher you will need to go to the Geometry tab and then scroll down to ZRemesher, click keepgroups if you split your mesh into different polygroups however if you decided not to use them then you don't have to select that. Then click the bigger button called ZRemesher and it will give you nice topology.
