SpeedTree is a suite of 3D-modeling tools that combines the efficiency of procedural modeling with the flexibility of hand modeling. Since its launch in 2001, SpeedTree has been used in hundreds of AAA and indie games and more than a hundred movies and television episodes. The software has earned a Scientific and Technical Academy Award and an Engineering Emmy, both in 2015.
Mesh-Based Smooth Normals
Leaf and frond meshes have new lighting properties allowing them to compute smooth normals based on the mesh after procedural deformation has been applied (this was only approximated in previous versions).
Quad indices for triangle only meshes are computed with a new, faster algorithm that creates more evenly distributed quads. This is particularly noticeable on high poly meshes.
File Dialog Crash
The crash associated with previously available drives no longer being accessible has been fixed.
Lumberyard Face Winding
The face winding for Lumberyard exports has been modified to work with both the vegetation shaders (this always worked) and non two-sided shaders.
A bug where shell generators could be mapped incorrectly during unwrapped exports has been corrected. Small items that were scaled up could cause overlapping in the atlas – this issue has also been corrected. In addition, an improvement has been made in the algorithm to prevent the unwanted expansion of tiny details.
