[Maya-Python] Using MArrayDataBuilder in python API 2.0

2021-07-02 Thread f.mi...@gmail.com 
I need a simple DG node that uses connected mesh and copies vertex 
coordinates to output MPoint array.
I am having trouble with setting this array with MArrayDataBuilder. It 
ether always stays zero-length or grows on every compute().
This surely must be simple to do, but I'm stuck. Can anybody help ?
One important detail - I need this array to be made of compound points so 
that I can query individual coordinates as attributes.

code:

My initial goal was to be able to read specific vertex coordinates, for 
example in expressions. So If I want to connect to, say 
outPoints[3].outPointsX - then I think compound attributes are my only 
choice.

Re: [Maya-Python] Using MArrayDataBuilder in python API 2.0

2021-07-05 Thread f.mi...@gmail.com 
Now I get it, Marcus. Good idea!
So I did test with floats and got some results. The exact same code with 
kFloat also fails, but I found something that works with kFloats (but not 
with Points).

Shortened version that works with kFloat:

outPointsH = dataBlock.outputArrayValue(self.outPoints)
outPointB = outPointsH.builder()
outPointB.growArray(len(inPoints))
for i, in_pt in enumerate(inPoints):
print(i, in_pt.x)
outPointB.addElement(i).setFloat(float(in_pt.x))
outPointsH.set(outPointB)
outPointsH.setAllClean()

Full code with 4 approaches, only one works: 
https://pastebin.ubuntu.com/p/CZr7ytX9C6/
My use case is very specific (and I will probably settle for something 
simpler), so I can live with floats instead of points.
Nevertheless I'd love to know how to dynamically set points array in API - 
this things always make me trouble.

thanks !

[Maya-Python] Check if timeline is playing Trax sounds

2021-11-29 Thread f.mi...@gmail.com 
 How do I query if timeline is using Trax to play sound ?

There seems to  only be options to query for individual sound nodes:

[Maya-Python] Re: automating a render

2025-11-26 Thread f.mi...@gmail.com 
are you rendering with standalone arnold kick.exe? If yes, here's part of 
code ripped from my setup to export .ass files:



import maya.app.renderSetup.model.renderSetup as renderSetup

def RenderCacheExport(renderLayers, frameList):
tryAttr("defaultRenderGlobals.animation", 1) #tryAttr is a wrapper 
around setAttr
tryAttr("defaultRenderGlobals.extensionPadding", 4)
tryAttr("defaultArnoldDriver.halfPrecision", 1)
tryAttr("defaultArnoldDriver.tiled", 1)
tryAttr("defaultArnoldRenderOptions.bucketScanning", 0)
tryAttr("defaultArnoldRenderOptions.enableProgressiveRender", 0)


for f in frameList:
mc.currentTime(f, e=1)
for rl in renderLayers:
render_setup = renderSetup.instance()
renderLayerList = render_setup.getRenderLayers()
renderLayerList = [l for l in renderLayerList if l.name() == rl]
render_setup.switchToLayer(renderLayerList[0])

mc.setAttr('defaultRenderGlobals.imageFilePrefix', f
'c:/temp/out_{rl}_{f}.exr', type='string')
mc.arnoldExportAss(cam='|persp', f=f'c:/temp/out_{rl}_{f}.ass')

[Maya-Python] Re: I can't build plugin for maya 2026

2025-11-26 Thread f.mi...@gmail.com 
Some DLLs can't be found and loaded. You could try Dependency Walker 
 and try to find what DLL is 
missing. Start it from maya session (for example with MEL: system 
"c:/.../depends.exe") and load your MLL plugin file. From there you may be 
able to find what is missing.
