[Maya-Python] feed user input value back to an attribute
Hi everyone, I am new to the forum. Please bear with me if my question sounds too vague. Trying to create a simple spreadsheet-like interface to list the value of selected attribute and be able to update/feed the user input value back to the attribute shown in Attribute Editor. Here is the mock up code. import maya.cmds as cmds cmds.window(title = test window, w=400, h=600, mxb=False, mnb=False) mainLayout = cmds.columnLayout(w=400, h=600) cmds.tabLayout(imw=5, imh=5) vrayMtlList = cmds.ls(type = VRayMtl) cmds.columnLayout(Material matte ID, w=400, h=600) for vrayMtl in vrayMtlList: if cmds.objExists(vrayMtl + .vrayMaterialId): currentMatteID = cmds.getAttr(vrayMtl + .vrayMaterialId) matteIdValue = cmds.intFieldGrp(numberOfFields = 1, label=vrayMtl + _matteID, value1 = currentMatteID) cmds.showWindow() I was able to get a simple GUI with integer fields show up with current VRay material multimatte ID displayed. I want the Attribute Editor multimatte be updated when users type in new multimatte ID and press the Enter or hit a Button, but could not figure out how. I have tried to define a function to be called in the intFieldGrp or see if I missed a flag that can achieve this easily. Any input would be much appreciated.

[Maya-Python] 'module' object has no attribute

Hey Zeth, Sorry for the late response. Much appreciated for the attached script. It seems to be super handy tool. I am able to download the attachment just fine. Will definitely give that a go and let you know. cheers, Jason On Wednesday, February 21, 2018 at 12:43:07 PM UTC-8, zeth willie wrote: > > Hey Jason- > > I've attached a script that I wrote a while back that may be useful for > stuff like this.

Re: [Maya-Python] 'module' object has no attribute
Thanks Marcus. Just tried that and apparently it's executing from the Maya 2017 scripts folder print(assetManager) If I remove the assetManager.py from Maya 2017 scripts folder, everything is fine. Is there a way to tell Maya 2018 to execute from the 2018 script folder instead of the 2017?

Re: [Maya-Python] 'module' object has no attribute
Thank you for the tips Marcus. As checking the PYTHONPATH, I guess the
problem was I have an older version of assetManager.py saved in the 2017
scripts folder and that directory is part of the PYTHONPATH directories
Maya will look for modules. Maya 2018 might parse the 2017 scripts
directory and execute the older version of assetManager.py first.
cheers,
Jason

Re: [Maya-Python] 'module' object has no attribute
ha...you are right. The 2017 scripts directory indeed shows up in front of
the 2018 one based on the order listed. Seems like my Maya 2018 is going a
bit bananas... :)
Now I know what's going on and a solution. Thank you, Marcus!

Re: [Maya-Python] 'module' object has no attribute
Works like a charm, Zeth. I am able to add, delete, move order of python paths in a nice little GUI. Awesome!

[Maya-Python] set VRay rect light target position via Python
Hi all,
I am trying to set a VRay rect light's target at the world origin.
I first try to modify the mel code to Python. With moving a rect light's
target in the viewport, I got the code below as a starting point.
setAttr "VRayLightRectShape1.targetPos" -type double3 14.13 -108.221315 -
203.228502 ;
However, when I execute this as MEL, the target isn't moving at all.
setAttr "VRayLightRectShape1.targetPos" -type double3 0.0 0.0 0.0 ;
I have also tried anyway in Python the following code.
cmds.setAttr('VRayLightRectShape1.targetPos', 0.0, 0.0, 0.0, type="double3")
There is no error but nor is the light's target moving to the world origin.
Is there a way to access a Rect light's target and set its translate or an
efficient way to set a rect light pointing at the world origin or a locator?
Thanks!
