File referencing
- Lattices cannot be unlocked when referenced limitation fixed
Level of Detail settings and CPU usage
Modeling
Vertices moved when using Split Polygon Tool revert when the tool is completed
UVs normalized when creating primitives
Corruption of user defined normals when using Combine feature
Corruption of user defined normals when deleting a face within a polygon mesh
User defined vertex normals lost when editing meshes without history
Retriangulation results in indices for user defined normals, colors, and UVs being re-indexed
UV shells become unselected and invisible when using Move UV Shell Tool
Coils for Helix primitives constructed incorrectly when units are in meters
Interactive primitive creation does not snap correctly in Y axis
Split Polygon Tool produces inaccurate results when splitting across multiple faces
Split Polygon Tool doesn’t slide vertex to the end of an edge
Character setup
FBIK and mental ray
Previously, when rendering with mental ray, skeletons driven by full body IK (FBIK) would not animate properly if mental ray's Optimize Animation Detection setting was on.
Rendering
MEL commands for batch rendering
The following MEL commands now work in Maya 8.5:
All of the -pre/-post commands (for example, -preFrame/-postFrame) now work with batch rendering for mental ray for Maya.
The -preRender and -postRender commands now work with batch rendering for the Hardware renderer.
Rasterizer
Changing the number of rendering threads to use in the mental ray Batch Render Option window has no effect
Interactive addition and removal of satellite hosts
Recognize .map files with alpha channel
Light linking works with surfaces with multiple shader assignments
mental ray for Maya exports the necessary include and link statement in .mi files
NURBS surface texture warp feature now supported
Dummy shaders no longer needed for .mi files containing only phenomena
Exact Motion Blur artifacts fixed
Hardware rendering
High Quality Render and Isolate Select
