Note: You must have at least one paint layer created and selected to paint on a model. The Create New Paint Layer window appears the first time you try to paint on a model if there are no existing layers.
To create a paint layer
- In the Paint Layers window, select
> New Layer or click the New Layer icon 
at the top of the window. The Create New Paint Layer window appears.
- In the Create New Paint Layer window, do the following, then click OK:
- (Optional) Enter a Name for the layer.
-
Select the Size (resolution) for the image by selecting a number that represents the number of pixels along X and Y for the image (square aspect ratio - 256, 512, 1024, 2048 (default), 4096, or 8192). The larger the image, the finer and sharper the detail you can apply when painting.
Note: The option to create an 8k texture map (8192) is only available on Windows and Linux systems, and only when your machine has sufficient memory available (the GPU has greater than 512 MB free). - Specify the image file format and bit depth (8, 16, 32) for the image you are going to paint using the Save As drop-down list. For a list of supported image formats, see Paint file formats and color bit depth.
- Specify on which paint channel to apply the paint (and how it appears on the model as a result).
For example, if you want the paint to appear as the diffuse base color material for the model, select Diffuse (default). For more information on the channel types, see Channel.
