Test Your Knowledge

1.

How do you save a material you’ve created?

2.

How can you batch import images to use for channels in a material?

Exercise

1.

Navigate to Tools > Material Ingest Tool.

In the Stream Configuration section, define the following options:

2.

Set your Shader Model to Principled BRDF.

3.

Set Case Sensitive to Yes or No.

4.

In the Stream Name column, disable the checkbox if you want to skip the creation of any images for that channel.

Tip:  To disable multiple channels at once, Ctrl+click the required rows, then right-click and select Uncheck Selected. Likewise, select Check Selected to enable the channels.

5.

Against each channel, change the Naming Patterns to the naming conventions of your images if they differ from Mari’s predefined ones.

For example, for Base Color, change the Naming Patterns to "diffuse" if your Base Color channel is called "concrete_diffuse.exr". The same applies to Specular, Roughness, etc.

In the Ingestion Options section, define the following options:

6.

Set Search Root Path to the directory where your images are stored.

7.

Depending on the naming pattern information of your images, set the Filename Template.

For example, for "concrete_diffuse.exr" enter %NAME_$STREAM.$EXT

8.

Choose the Ingest Method, whether to export your materials to disk or build them in your project.

9.

In the Procedural Type field, select which image based procedural node to generate materials with: Tiled or Tri Planar Projection.

10.

In the Add to Shelf field, select which shelf to add your materials to.

11.

Click the Create Materials button.
