When enabled, the billboards will be placed in the texture atlas rather than in a separate billboard atlas texture. This property is also mirrored by the “Merge” option in the atlas view toolbar.

Minimum size of the combined texture and billboard atlas. It may need to expand to fit all of the textures.

Choice of layout algorithm for the texture atlas between one that works better for similarly-sized textures and one that works better for textures of various size.

Size of the billboard atlas.

Choice of layout algorithm for the billboard atlas between one that works better for similarly-sized textures and one that works better for textures of various size.

When enabled, smaller billboards will be scaled up to use any wasted space in the atlas. This is an iterative process, so it may increase layout time.

When pressed, every tree in the atlas will have its billboard size scalar reset to zero.

The background color for the diffuse layer of the texture/billboard atlas

The background color for the normal layer of the texture/billboard atlas

The background color for the specular layer of the texture atlas

The texture layout algorithm has a measure of randomness to it. If a layout does not seem optimal, try modifying the seed to get different results. This seed is used for the texture atlas.
