6/11 Texturing with Substance Painter

Today’s class is about how to create custom textures for our 3d models using substance painter. The whole concept of how SP works is pretty straightforward. It is very similar to Photoshop where we paint with masks and layers.

Substance Painter offers a bunch of materials and smart materials that are packaged with the program. Creating custom materials with substance designer or importing existing smart materials is also possible. Most of the existing materials are not exactly usable straight out of the box. But they can be modified or used as a base start point to create the final texture.

I think the most important thing for texturing would be that whatever the artist choose to add to the materials must have their reasons. And that reason is to sell the story and concept.

The image below was a test image that I did for the class. I was trying out the different brushes and materials in SP.

Texturing is the next step after UV unwrapping. I feel that it is a important step as it gives the 3d model life. It gives the asset a reason to exist. Without textures, the whole 3d environment will just be plain and dull white clay material. I would definitely be using more SP to create textures for future projects.

30/10 UV Texturing

UV mapping is the process of generating a flat representation of a 3d dimensional geometry. This UV map can be represented by UV coordinates which are also known as texture coordinates. Since it’s 2d, the two parameters it are U for the X-axis and V for the Y-axis.

Applying textures – right click assign material (either existing or new material)

Creating materials – edit from hypershade

Maya’s UV editor – interface to edit UVs if needed, auto unwrap works most of the time.

Demo example: Earth and Moon

As most of the modeling work will be done in Maya, the next step will be to UV wrap them. Having proper UV maps is very important to ensure the textures does not appear in the wrong places of the model. For the class activity, we are tasked to texture two different spheres with the earth and moon’s texture from online sources. The task was pretty straightforward as when unwrapping a UV sphere the projection is already the same as the geographic projection of the images (Mercator Projection being the most popular for maps). All we have to do was to auto unwrap and apply the textures with a standard material in Maya. I look forward to further texture lessons.
