The Drop Spider Venom Engine Feature List Deferred Render A deferred render is a scene based rendering system that performs lighting (and shadows) as a whole, rather than polygon by polygon. As lights are applied separately as polygons in 2D, the number is virtually unlimited, with no hard-coded limit due to size of pixel shaders and so forth. Multi Track Animation A skeletonal animation system via a multi-track blender as standard, allowing runtime mixing of clips and sub-sections of clips. C++ Game Engine Runtime engine code is a C++ engine built on two layers, a general drop spider framework and a venom game engine specific. Python Build System The build pipeline is written in python, and utilises the C++ framework for common types and utilities, via python extensions. As such all tools are easily combined, and can optionally be driven by a build system such as SCons. Render Primitives Static mesh, layered particle effects, skinned mesh and height-map terrains. Also a static mesh instancing system for fast rendering of normally poor overhead to polygon count like eco systems.
