Ultra Engine 0.9.6 is here, with a new foliage system that replaces and improves the vegetation system used in Leadwerks. Whereas Leadwerks uses a geometry shader, Ultra uses a compute shader that provides more power and better performance. The most significant improvement is the inclusion of sublayers, which allow a mesh layer to use multiple variations to easily populate a scene with a variety of different objects, while spacing them out in a natural way.

Imposters

Imposters are also added, which allows high-poly meshes to be reduced to just a single quad when they are viewed from a distance. This feature can be used with or without the foliage system. A series of images are generated for color, normal, and metallic/roughness values, to provide an accurate representation of the object from any angle.

Nature Starter Kit DLC

The first DLC for Ultra Engine is the essential Nature Starter Kit, which provides trees, plants, and rocks for your outdoor environments. This free DLC is available for Ultra Engine Pro, Standard, and for the standalone version of the engine from our site.

New Animation Tools

The model editor interface has gained several new tools focused on improving support for animation. Animations can be loaded from external files, partial animation sequences can be extracted and added as a new sequence, and bind poses can be reset.

Free Web Assets

The new Asset Library provides an interface to install both DLCs, and to browse and download remote content from third-party providers. The first official integration is with AmbientCG.com, providing instant access to more than 2000 game-ready PBR materials.
