Game Design - Environments using ZBrush, Substance and Unity

Game Designing for Environments Using ZBrush4 R8

Lets gather reference for our project.

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. Saving references
2. Scaling inside Maya (Please note you can bypass this step as Unity works by numeric inputs rather than real world scaling)

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. How much default grid space does a 1 metre cube take up in ZBrush
2. Importing our 1 metre cube exported from Maya

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. Lets model our first rock using the cube as our base

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. We will create a lower poly model from the high geo
2. We will project detail onto the lower resolution rock from the higher

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. We will check the scale and could change this in Maya we will use GOZ again to do this
2. Unwrapping our low poly rock
3. Checking the UVs with a texture map

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. Lets use spotlight to apply a texture
2. We can now use cavity masking to create a darker area in the recesses of our model
3. I also want to show you how to get this into Photoshop to check texturing inside here which will give you a better result as its not using vertex painting which is what you are painting with inside ZBrush (polypainting)

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. We will use both ZBrush and Photoshop to combine passes to a texture map compositing inside Photoshop
2. I will show you how to create an alpha from a texture and then mask by that alpha to drive detail straight from the texture to the model

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. We will export direct from ZBrush and discuss problems with flipped Vs
2. I will show you how to edit a texture for a colour tint in Photoshop
3. We will open up and apply the exported maps inside Marmoset Toolbag3

Or first venture into substance painter in this we will use the rock we created and I will show you how to export out the texture and how to bake our maps from low to high inside substance

During this lecture we will discuss the following points:
1. Export for substance Painter
2. Export maps from Substance to Marmoset Toolbag 3

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. Lets take a look at tiling and how it can help us this will be the first time we have jumped into Unity this is a demo only for you guys to watch

Game Designing for Environments Using ZBrush4 R8

Not that I do a great job here but the point I think is made by using a Photoshop and creating a tileable texture

During this lecture we will discuss the following points:
1. Create a tile inside Photoshop and apply to a plane in Unity

Game Designing for Environments Using ZBrush4 R8

Now we will grab some tileable texture available online via Google! a point to remember make sure your not breaking any copyright violations by using anything online unless you have paid for it for commercial use!!!!

During this lecture we will discuss the following points:
1. lets check out some textures already created online and try a few inside Unity

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. We will create a tileable texture inside ZBrush using wrap mode
2. We will export the maps out and into Unity to test

Game Designing for Environments Using ZBrush4 R8

OK during this lecture I just want to show you a few things with the tiling and discuss our next phase, we have covered tiling so it should be clear what you can achieve with very little texture space.

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. Using the techniques we have already covered I am doing a quick timelapse of the modelling process

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. Lets create the low poly version
2. Lets UV unwrap by poly group

Game Designing for Environments Using ZBrush4 R8

In this lecture I will export the maps and bring it into Unity where will will set it up

During this lecture we will discuss the following points:
1. Exporting maps direct from ZBrush
2.Creatign additional maps from ZBrush
3.Create and add the material inside Unity

This lecture is to show you how we can bypass Substance painter if we want to

Game Designing for Environments Using ZBrush4 R8

OK so we have covered the basics lets move on to the final project a whole terrain!

During this lecture we will discuss the following points:
1. Blocking in Our shapes

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. Further refinements
2.Timelapse

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. Lets create a low poly version
2. Now we will break the model up into polygroups

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. We will Dynamesh our blocks
2. We will create a new ground and project details from the high poly ground parts

Game Designing for Environments Using ZBrush4 R8

Part 1

During this lecture we will discuss the following points:
1. Adding to the terrain
2. Terrain Cleanup

Part 2

During this lecture we will discuss the following points:
1. Adding to the terrain
2. Terrain Cleanup

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. Lets prepare our low res versions of the terrain blocks

Game Designing for Environments Using ZBrush4 R8

In this lecture I will show you how you can export direct from ZBrush each terrain block, we will then do the export and map merge to Substance in the next lecture!

During this lecture we will discuss the following points:
1. Exporting and UV unwrap in and out of ZBrush

Game Designing for Environments Using ZBrush4 R8

During this lecture we will discuss the following points:
1. Lets import into Substance
2.We will make sure the imports is on one material texture set, rather than individual Materials per subtool!

Game Designing for Environments Using ZBrush4 R8

To make sure all export options are covered I am going to show you another approach to the export and import from ZBrush to Substance with this new approach you will see how you can still use ZBrush to produce different maps in Substance from ZBrush polypaint data
