hi I want to make a texture set for use in another 3d program like substance painter so that the models head body etc is a seperate texture set. i don’t know how to do that in zbrush. any help would be appreciated thanls
Creating a new texture set is an easy process in zBrush.
Texturing is typically manifests itself two ways:
- Sculpting hi res details on your model such as using alphas and noise
- Applying polypaint to your model via: [LIST=1]
- Spotlight
- Polypaint from texture
- Or applying polypaint to your model using the standard brush
[/LIST]
Textures are best created when the model is hi res or to mean sub divided into millions of polygons.
The following steps assume your model is sub divided into millions of polygons:
- Choose the standard brush
- Turn off zAdd and/or zSub
- Turn on M and ensure MRGB and RGB are off
- Choose/select a material for your model. The color will completely consume your model/sub tool
- Go to the color menu and click Fill Object
- Turn on RGB ensure M and MRGB are off
- Position your model in the canvas so that you have a good view of the model. Click Frame button if necessary
- Choose a color from the gradient and paint on the model or parts of your model a base color
- Now vary the colors as you see fit and start painting over the base color on various parts of your model. You can change the way your standard brush applies poly paint by use alphas and color spray. Adjust your RGB intensity often when painting to append additional details of color. Also use mask by cavity and inverse mask to paint on tiny areas of your model.
- Ounce you are satisfied with your poly painting if necessary create a UV using UV master at Low Res (not HI Res). I won’t go into that because this is not the question being asked. If the model you are painting already has a UV on it then you can skip this.
- Assuming you created a UV set [LIST=1]
- Return your model back to hi res
- In the right tray, your tool palette, go to Texture Map sub menu and click New From Polypaint. This will create a texture based on the UV.
- While on Texture Map sub menu click Clone Txtr.
- The menu, top row of the zBrush UI, select Texture and click Export
- Name and Save the export to a desired location
[/LIST]
That’s it. Your textures are now a file that can brought into another 3D a program. Do not forget however that normal maps and displacement maps are equally important than color texture maps.
Other things to consider when poly painting:
You can isolate areas of your model using polygroups so that polygroup is the only part of your model showing when you paint on it. This prevents any other part of model from being painted on.
You can also isolate areas of your model, when your model is composition of sub tools. Each sub tool is painted individually and is contributing piece to the overall model.
You can use masks to prevent areas of your model from being painted on or to isolate areas to paint on. For example let’s say you have this really small area on your model you want to paint. So you mask that small area, and then inverse that mask to protect the rest of the model and then you can apply paint as need over the small area.
