Hey guys,
I was wondering, what is used for what and what are the advantages? Do I need Decimation master now that we have zremesher?
What do you think, please? I’m still new to this :))
You are comparing apples to oranges here. ZRemesher is not meant to be a replacement for or substitute to Decimation Master. They are both different tools that are used for different reasons. In a nutshell, ZRemesher is basically an auto retopolgy tool. Decimation Master is meant to optimize the point count of the mesh without sacrificing detail. For a better understanding of ZRemesher, please read pages 19 to 25 in the ZBrush 4_R6_whats_new.pdf in the Documentation folder of you ZBrush directory.
So it means that first I do Decimation master and then I do zremesher to get it ready for animation? Do I lose any details for later? Sorry for noob questions but I’m new to zbrush so I have tons of questions 
The tutorials are great but sometimes don’t tell you what is used for what ie. in which scenario you want this over that
You don’t need to run one prior to running the other.
Basically with zremesher, you will lose more surface detail but end up with a mesh that has a nicer edgeflow for sculpting and animation (the lost detail can then be projected back onto the mesh, or captured through a texture).
With decimation master, the goal is going to be to preserve surface detail at all costs while throwing any concept of good edgeflow out the window. This can be useful to use on a highpoly sculpt before trying to export it into another program that might not be able to handle 40million verices, but the majority of the time its not something you’d want to use to create a mesh that needs to be animated.
So in my case if I am looking to create a model that I will animate later then I don’t need toworry about decimation master as I will do zremesher and then I could sculpt the details on top of htat and use it as bump & displacement?Do you think that could pose issues with animating skin on the face if that is what I go for?
If you have a high poly model then it can be useful to run Decimation Master on the model before running ZRemesher - it will reduce the load on ZRemesher and you’ll get the results more quickly. For example, if you are importing a 3Dscan for working on in ZBrush.
I guess the best way for me will be to come here and show the model before the changes. That way you can tell me what is the best thing to do and I will also learn on a specific example. It will be easier to understand also
Pictures always help. But remember that ZRemesher is an automatic solution and as such will not create ‘perfect’ topology. Creating topology that is good for animation is a topic beyond the scope of this forum but there will be situations where doing it by hand is the only way to get the result you want.
