Fixed rendering of metablobs (and fixed a possible crash with metablobs containing tori).
Fixed a potetial issue with position of Ecosystem instances when populated over a procedural terrain using Displacement Mapping.
Fixed bad handling of degenerated meshes (resulting from a strong decimation, for instance) used with Displacement Mapping.
Fixed baking to polygons of booleans with terrain.
Fixed rendering of booleans with meshes and/or terrains.
Fixed a potential crash when reloading a scene containing a baked boolean.
Fixed Eco-Painting over planetary terrain, when current view's zoom is very low.
Fixed loading of Poser 8 models on Mac.
Fixed a possible crash in Render Scene Preview when loading scenes that contained EcoSystem instances.
Fixed edition of HLS/RGB values in the color map editor.
Fixed import of opacity for objects created with MaxToVue.
Removed useless "Poser Pro" version from the Poser import options dialog - Poser Pro users should import their models using either the Poser 7 or 8 option.
Fixed some issues with populating EcoSystem on spherical terrains.
Fixed HyperVue crash when rendering Poser animations.
Various OpenGL imporvements on MacOS.

New Features in Vue 8.4:

Improved Displacement Mapping: computation and rendering of displaced materials on standard terrains is significantly faster and more memory efficient.
Multi-Materials: new Multi-materials allow users to change all materials of any given object in a single operation. Multi-materials can be saved for future use, copy-pasted or drag-dropped between different objects in the scene.
New Material Control: new "Relative to sea" material mapping option, and "Sea level" input node.
User-definable units in Function Graphs: "External Dependency", "Distance to object below", "Distance from camera", etc nodes now express object dimensions in user-definable real-world units.
Easier Pose/Motion Handling: the new Motion Browser lets users visually select and interactively preview preset poses and motions for rigged meshes.
EcoSystem Display Improvements: the rendering of shaded EcoSystem billboards is improved to provide more accurate coloring and reduce flickering when moving around the scene.
Other Artistic Control Improvements: the render area and the collections browser can be locked to avoid accidental modifications, materials mapped in World coordinates are now accurately previewed in OpenGL, GPU resources can be easily monitored in the status bar, objects can be copy-pasted to hidden or locked layers, and more...
Other Performance Improvements: faster high quality previewing in OpenGL, automatic resizing of render buckets to maximize use of all cores on small renders, faster handling of complicated group hierarchies, default views are automatically resized to adjust according to internal units, and more...
