Tracking Zone and Rendering Area

Once the texture is selected, we are back in the Texturize window.

The texture appears on the left in the window. Under its name and format, we can see a thumbnail. It is possible to change its name if needed, and also to quickly remove a texture with the cross on the right.

It is of course possible to add several textures for the different areas of the animation. They then appear one above the others in the left column.

Reference frame : thanks to the numeric field or the adjecent mini-slider, you can choose to begin at whatever intance you wish.

Reset tracking : active by defaut, will be useful and explained later on this chapter.

There is two areas to define in the right part of the window :

The Tracking Zone : where the chosen colors will act as a guide to the texture.

The Rendering Area : the color(s) upon which the texture will be applied.

By clicking on Select colors we find the CTG Layer's color list. If they have been named with the Edit colors option, the names will also be there.

Click on the colors square or on their name to select one or more colors.

Click outside this list to exit it.

In our example, the Bob project, the two colors of the scarf can be checked.

It is not mandatory for the Tracking zone and the Rendering area to be of the same color. You can indeed choose a Tracking zone that is less in movement than your Rendering area : it will be easier to control the texture on a more fixed color zone.

For example, in the case of the animation of a lion's head, it will be easier to choose the face's color as a Tracking Zone (as it will not move much) to have a texture on the mane as a Rendering area (as it will be more animated than the face).

It is highly advised to track as little colors as possible. Rendering areas don't have this restriction.

Once you selected the two zones, click on Start.

If you forgot to select a color in one of the zones, this message will appear after clicking on Start.

If you choose a Reference frame other than the first instance, TVPaint Animation will act this way : in the Bob project, if we start from image 5, the texture will be applied on the following images, from left to right : 6, 7, 8, 9, etc, until 16. The texture will then be applied on the images 4, 3, 2, 1, in this order, from right to left.
