Hello Chadrik,
Yes absolutely.
The certain shaders I mention are CGFX shaders and for some reason Maya
crashes when trying to apply said shader in Batch although I may be using
the wrong call to apply them. The full function below illustrates use-age
of both the hypershade command and the CGFX application:
def createReplacementCgfx(material='', texturePaths={}, cgfxChannels={},
cgfxShaderPath=''):
""" If we find a shaderFxShader type material we need to replace wiuth
CGFX for export purposes """
print 'Replacing shader with CGFX'
#mel.eval('cgfxShader -fx "%s" ' %cgfxShaderPath)
matName = str(material)
shader = pm.listConnections(material, type='shadingEngine')[0]
members = list(set(shader.members(flatten=True)))
pm.delete(matName)
print 'got members'
if 'diffuse_layer0_texture' in texturePaths:
newMat = pm.shadingNode('cgfxShader', asShader=True,
name=matName)
mel.eval('cgfxShader -e -fx "%s" %s;' %(cgfxShaderPath,newMat))
for key in texturePaths:
slot = cgfxChannels[key]
texture = texturePaths[key]
newFileNode = createFileNode()
pm.setAttr('%s.fileTextureName' %newFileNode, texture,
type='string')
pm.connectAttr('%s.outColor'%newFileNode,
'%s.%s'%(newMat,slot), force=True)
print 'connected', newMat
pm.select(members)
pm.hyperShade(assign=newMat)
print 'CGFX function complete'
Cheers,
Ben
