pymel.core.windows.modelEditor¶

modelEditor(*args, **kwargs)¶

Create, edit or query a model editor. Note that some of the flags of this command may have different settings for normal mode and for interactive/playback mode. For example, a modelEditor can be set to use shaded mode normally, but to use wireframe during playback for greater speed. Some flags also support having defaults set so that new model editors will be created with those settings.

Modifications:

• returns a PyNode object for flags: (query and camera)

textureEnvironmentMap / tem		bool
	If true then use a texture environment map
textureHilight / th		bool
	Set whether to show specular hilighting when the display is in shaded textured mode.
textureMaxSize / tms		int
	Set maximum texture size for hardware texturing. The integer value must be a power of 2. Recommended values are 128 or 256. If the value specified is larger than the OpenGL maximim textures size for the graphics hardware it will be clamped to the OpenGL size. If many large textures are used in a scene reducing this value improves performance. On Impact texture memory is pinned in RAM so using large textures can cause reliability and performance problems. Again reducing this value will help. Software rendering does not use this value. This flag is obsolete as of Maya 6.5. The maxTextureResolution/mtr argument on the displayPref command should be used instead.
textureMemoryUsed / tmu		bool
	Returns the total number of bytes used by all texture maps. This is typicly width*height*channels for all texture objects in the scene If the texture is mip mapped all mip map levels are included in the total though not never more than two level will be in use at one time
