General
Viewport 2.0 supports all common workflows in Maya, with the exception of the following limitations:
- Cameras
-
- You cannot map textures to the
Zero Parallax Color attribute.
- Currently, there is no support for multi-sample anti-aliasing for stereo display modes.
-
Selection Highlighting
-
Selection highlighting cannot be turned off for the following:
- Cone shapes created from
Create > Volume Primitive > Cone
- Deformers:
- Axes of the lattice deformer
- Position and orientation marker numbers
- All non-linear deformers
-
Create > Measure Tools
- Polygon sorting
-
- Backface Culling
-
Backface Culling does not support the following:
-
Display > Polygons > Culling Options > Keep Hard Edges
- The
Display Tangent attribute in the shape node's
Mesh Component Display attribute group.
- Ghosting
-
-
Custom Key Steps
- Ghosting of deforming geometry not supported
- Fading of ghost color not supported. This feature is deprecated.
- Bullet
- Bullet objects are not supported when Viewport 2.0 is running in OpenGL - Core Profile (Strict) or DirectX 11 mode. Use OpenGL - Core Profile (Compatibility) or OpenGL- Legacy mode when using Bullet.
- Toon
- Ramp textures are not supported on the Toon shader
Shading
The following shaders are supported as
baked:
-
Brownian
-
Cloud
-
Crater
-
Granite
-
Leather
-
Water
-
Wood
- 3D-procedural bump mapping
The following shaders are
not supported:
-
Light Fog
-
Particle Cloud
-
Surface Info
-
Surf. Luminance
-
Ramp Shader Limitations:
-
Normalized Brightness
Color Input mode is not supported for
Color ramp
-
Forward Scatter not supported
- Conversion of .HDR linear image to display color space is not supported through exposure controls
- particleSamplerInfo node only supported for
Sprites
Lighting
- Ambient lights in Viewport 2.0 do not respect the Ambient Shade attribute
- Light linking is not supported in Viewport 2.0.
- Light instances are not supported.
Viewport 2.0 Platform
- Viewport 2.0 is currently not supported on the Mac OS X platform for the ATI Radeon X1900 Gfx card.
- There is a known driver issue on some (particularly older) Linux platforms with PCI Express 1.0 that can force Viewport 2.0 back to a software path. This can result in dramatically slower performance. This issue may be fixed by newer drivers.
- Remote display or indirect rendering is not supported on the Linux platform.
Mac OS X
- Slowdowns or Instability
- You may encounter either extreme slowdowns or instability due to memory management issues on Mac OS X when you push close to your graphics ram limit. To possibly alleviate this problem, set the texture size used for viewport display when loading in file textures for the renderer. Use the following procedure:
To set the texture size used for viewport display
- Set the environment variable : MAYA_OGS_ENABLE_MAX_TEXTURE_SIZE_PREF to 1 before starting up Maya.
-
You can also set this environment variable: MAYA_OGS_CPU_MEMORY_LIMIT (to a value in MB) to the amount of memory you anticipate using for the renderer. The value should be smaller than the actual amount available on your machine.
- Mac OS X for graphics cards with less memory
-
When working in Viewport 2.0 on Mac OS X (10.6.x), instabilities may occur when too much graphics memory is used. For graphics cards with less memory, this situation may occur more frequently, since the memory threshold is smaller. A graphics card with 1GB of VRAM or greater is recommended for the Mac OS X platform.
Note: You cannot use Viewport 2.0 on Apple computer systems or hardware shipping prior to 2009. Upgrade you system based on
Maya Certified Hardware recommendations.
