Texture 2D

Textures 2D are asset used in many different contexts:

• to paint on the diffuse or the normal of a 3d mesh

• to create post-processes

• to make decals

• to draw storyboards

With Odyssey, Texture 2D are a little like “PSD” files inside Unreal Engine, and it is uses a Layer Stack.

A layer stack in digital illustration is a hierarchical arrangement of layers. It can be background, foreground, details. It can be used to organize and manipulate different elements of your artwork. It enables you to work on individual components separately and non-destructively, allowing for precise control and creative flexibility.

Layer properties

Alpha mask / eye / lock

Icon	Description
	The litle checkboard square icon is the Alpha Mask. It blocks the transparency levels in you layer. When enabled you can draw over opaque pixels and leave the transparent pixels as such.
	The eye icon makes you able to show or hide the layer.
	The lock makes you able to lock or unlock the layer. Once locked you can not edit you layer.

Opacity

Change the opacity of a layer. You can click and enter a value or use the slider.

Blending modes

These modes alter the way colors, tones, and pixels from one layer interact with those of layers beneath, resulting in various visual effects.

Tip

Use the search engine at the top of the list to easily find a Blending mode.

Layers types

Click on the button “Add Layer” and choose either “Raster Image Layer” or “Vector Image Layer” to add a layer.

Raster layer

A Raster Layer is an image layer composed of pixels, where each pixel contains color information, and it’s commonly used for bitmap graphics.

Vector layer

A Vector Layer is an image layer consisting of mathematical paths defined by points and lines, allowing for scalable and editable graphics without pixelation.

Vector Layers displays two additional icons:

• monochrome mode to hide all vector Paint Buckets (read this page to know more about vector Paint Bucket)

• wireframe mode to identify gaps in the vector object

When creating a Vector Layer, you also create a “Scene” of infinite size, which will contain all your future vector paths and shapes.

Folder

To create a new folder click on Add Folder Button. You can then drag and drop layers inside.

Other Actions

Multiple Selection

Use Shift to select contiguous Layers:

Use Ctrl to select non-contiguous Layers:

Use Ctrl+A to select all Layers:

Note

For the last one, Ctrl+A will only work if the Layer Stack is selected.

Contextual menu

Make a right click on top of a Layer to display various options:

• Select All: Select all Layers from the stack.

• Duplicate: Duplicate selected Layers.

• Rename: Rename the current Layer. You can also hold the click to rename a Layer.

• Cut: Cut the selected Layers.

• Copy: Copy the selected Layers.

• Paste: Paste Layers that were copied or cut.

• Delete: Delete the selected Layers.

• Merge Selected Layers: Merge selected Layers that have the same type (Raster or Vector). You cannot merge Layers with 2 different types.

• Flatten Selected Layers: Flatten selected Folders.

Note

Flattening folders only works with Raster Layers inside. Vector Layers will be ignored.

Tip

If you display the Contextual Menu on a Vector Layer, you will have the option to convert it to a Raster Layer.

Drag and drop

You can drag and drop Layers from a Texture 2D to another.
