python - 如何在maya中查询当前视口(viewport)渲染器

Question

有人有好的解决方案可以在 python 中查询当前的 maya 视口(viewport)渲染器(Viewport 2.0、默认视口(viewport)、高质量视口(viewport))吗？

Answer 1

@Tomek 的回答将非常有效。如果你要走 PyMEL 路线，你可以这样做:

import pymel.core.uitypes as pmui

model_panel = pmui.ModelEditor(pm.getPanel(withFocus=True))
print pmui.ModelEditor.getRendererName(model_panel)

不过，那段话似乎有些喜怒无常。它有时会抛出错误，提示找不到模型编辑器，尤其是在现成的情况下执行时。

另一种方式会有点罗嗦，但它每次都有效:

import pymel.core as pm
import pymel.core.uitypes as pmui

modelPanelList = []
modelEditorList = pm.lsUI(editors=True)
for myModelPanel in modelEditorList:
    if myModelPanel.find('modelPanel') != -1:
        modelPanelList.append(myModelPanel)

for modelPanel in modelPanelList:    
    if pmui.ModelEditor(modelPanel).getActiveView():
        try:
            # Always better to try in the case of active panel operations
            # as the active panel might not be a viewport.
            print pmui.ModelEditor(modelPanel).getRendererName()
        except Exception as e:
            # Handle exception
            print e

一种简洁的伪 PyMEL 方法是 PyMEL 化 Tomek 的回答:

import pymel.core as pm
print pm.modelEditor(pm.getPanel(wf=True), q=True, rnm=True)

获取视口(viewport)渲染器列表:

import pymel.core.uitypes as pmui
print pmui.ModelEditor().getRendererList()

这里有一些关于模型编辑器和视口(viewport)渲染器的额外信息。要获得他们的“友好”名称:

import pymel.core.uitypes as pmui
print pmui.ModelEditor().getRendererListUI()

要简明扼要地设置它们，我会使用 PyMEL 并执行以下操作:

import pymel.core.uitypes as pmui

# assuming you know which modelPanel you want to affect
pmui.ModelEditor("modelPanel4").setRendererName("ogsRenderer")

要影响所有视口(viewport)(模型面板)，我会这样做:

import pymel.core as pm
import pymel.core.uitypes as pmui

modelPanelList = []
modelEditorList = pm.lsUI(editors=True)
for myModelPanel in modelEditorList:
    if myModelPanel.find('modelPanel') != -1:
        modelPanelList.append(myModelPanel)

for modelPanel in modelPanelList:
    pmui.ModelEditor(modelPanel).setRendererName("ogsRenderer")

仅影响焦点中的视口(viewport):

import pymel.core as pm
import pymel.core.uitypes as pmui

modelPanelList = []
modelEditorList = pm.lsUI(editors=True)
for myModelPanel in modelEditorList:
    if myModelPanel.find('modelPanel') != -1:
        modelPanelList.append(myModelPanel)

for modelPanel in modelPanelList:    
    if pmui.ModelEditor(modelPanel).getActiveView():
        try:
            # Always better to try in the case of active panel operations
            # as the active panel might not be a viewport.
            pmui.ModelEditor(modelPanel).setRendererName("ogsRenderer")
        except Exception as e:
            # Handle exception
            print e
