OBJ: Obj files are typically for static models meaning they are simply the model. If you are unfamiliar with the differences of OBJ and FBX files the key points are as follows. This file type can only be used in Zbrush so any attempts to use this file type in game engines will be unsuccessful. Zbrush also has a native file type called ZTL or as referred to in Zbrush a Zbrush Tool. This means anything you create in Zbrush has the ability to be exported into a game engine. These files are the most common files used in most game engines for models. Zbrush File TypesĪs I have already mentioned Zbrush has the ability to export to common file types such as OBJ & FBX.
#ZBRUSH MODELS SOFTWARE#
If you are looking for a free piece of software I highly recommend xNormal it does a great job and is easy to use. Blender has this capability, however I’ve not always been impressed with its results. Unfortunately Zbrush does not have the ability to do what is referred to as Baking a Normal Map. In step one you reduced the number of polys and hence reduced the amount of detail, so a Normal Map is now required. Most game engines will have the ability to use this map as it is an essential part of the 3d game development process. This map emulates the way the light reflects off the model giving it more detail than your actual model does. Creating a Normal MapĪ Normal Map is a texture you can apply to your model that in a way fakes the details of the high poly mesh. You can find an article I wrote on this outlining them all here. These range from fully automatic to fully manual. Zbrush actually has ways you can do this in fact there are five. The retopologized version has less polys than the original and hence has less detail. Retopology is the process of recreating the models mesh so as to reduce the number of polys. Retopologize your model to a low poly version.This is why you will likely have to have to take these two steps to export your model from Zbrush. Your game simply will struggle to handle the computation required to render the model. This is not ideal for a real time rendering engine rendering at 30 to 60 frames per second. If you utilize Zbrushes sculpting ability there is a very good chance you will have a poly count in the millions. While you could technically simply hit export on any model you create in Zbrush this may not be the best choice. I personally have had the most success using the two programs in conjunction with each other working to their strengths. A direct comparison to Blender is not possible as they programs differ in the tasks that they can perform. Zbrush is not a replacement for software such as Blender it is a tool that specializes in modelling. It has the ability to texture and retopologize, however it cannot animate. It can be used for what is referred to as sculpting and box modelling. Zbrush specializes in the 3d modelling process. If your just getting into modelling or are considering Zbrush please check out my article here outlining the advantages and disadvantages of Zbrush. It can model game characters and props in a way that traditional software such as Blender or Maya cant. Who Uses ZbrushĪ lot of studios and professionals use Zbrush for game modelling as it gives a lot of versatility to sculpt. In this article I will outline what steps specifically are required. Some preparation of models before importing into a game engine may be required to assist with real time rendering workload. Zbrushes sculpting features can sometimes result in large amount of polys. It has the ability to export to OBJ or FBX formats which is the standard format used in game engines for 3d models. It is a popular choice in the industry and is widely used in a game 3d modelling pipeline. Zbrush can absolutely produce models for games. When investigating software such as Zbrush I’m sure you will have a mountain of questions and the first being can Zbrush produce models for games?
3d models for games have a more specific requirement than that of models meant for rendering images or movies due to their requirement to be real time rendered. There are a lot of 3d software programs available and at a glance it can be hard to understand what will meet your needs.
