  • (none ) – Purchasing: Fixed a bug where a duplicate transaction could fail without calling the failure callback.
  • (none ) – Scripting: Added the following non-allocating accessors to Mesh. These accessors write into a user-specified List. The accessors are GetBindposes, GetBoneWeights, GetColors, GetIndices, GetNormals, GetTangents, GetTriangles, and GetVertices.
  • (856507) – Shaders: Fixed shader compilation error when compiling certain surface shaders using WorldNormalVector from INTERNAL_DATA e.g. shadow pass variations.
