[Maya-Python] Custom Maya node, with iconName like dagContainer

[Marcus Ottosson]

Hi all,

I’m looking to implement this.

node = cmds.createNode("myCustomNode")
cmds.setAttr(node+ ".iconName", "polyMeasureUV.png")

And have the icon appear wherever this node is drawn, such as the Outliner and Node Editor. Ideally polyMeasureUV.png is one of Maya’s own internal icons, the ones you can browse via the Shelf Editor.

I know about the XBMLANGPATH but would like something that A) doesn’t require a restart or meddling with the environment in order to work (if that’s possible still using this approach, do let me know) and B) uses Maya’s own icon library such that I won’t have to ship custom images.

I’m chasing this, because I noticed the dagContainer have a feature like it and works quite well.

from maya import cmds
container = cmds.createNode("dagContainer", name="LegLeft03_LIM")
cmds.setAttr(container + ".iconName", "polyMeasureUV.png")

Any ideas?

Hi Marcus,

I was looking for this, too. Have you got any result ?

While I was googling, I found this page

https://knowledge.autodesk.com/search-result/caas/CloudHelp/cloudhelp/2018/ENU/Maya-SDK/cpp-ref/node-icon-cmd-2node-icon-cmd-8cpp-example-html.html

And that inspired me to use `MFnDependencyNode.setIcon()` to do the trick, but I end up using Maya Python API 1.0, since 2.0 won't work.

Finally, I put them together as a small tool and upload it

Although this thread has been here almost a year..., but welcome to have a try :)

Best,

David

Thanks David, that’s a great find. :)

from maya import cmds, OpenMaya as om

node = cmds.createNode("transform")
sel = om.MSelectionList()
mobj = om.MObject()
om.MGlobal.getActiveSelectionList(sel)
sel.getDependNode(0, mobj)
fn = om.MFnDependencyNode(mobj)
fn.setIcon("polyTorus.png")

Since then, it’s turned out that setting XBMLANGPATH during userSetup.py works just fine, except on Linux in which case setting it prior to launching Maya hasn’t been as much of a problem as I initially expected.

I did come across an .iconName attribute only a few weeks ago, present on all nodes since at least Maya 2015, but quickly dismissed it as I couldn’t get it to work. it doesn’t seem related either, as seems to be for the Hypergraph specifically.

I had a look at your “NodeSticker” code, and it looks like you’ve identified a few issues with the idea, primarily that the set icon isn’t stored with the scene; what a shame! Such a small thing. It means you’ll either need to manually call something whenever you open a scene (tedious), or install a callback for scene-open, or node-creation that can call it automatically (complex).

In my experiment just now, it looks like some icons are preserved (in this case, in 2018 on the defaultObjectSet) but not others; likely only in the current Maya session; as though that node is never actually deleted on scene new/open (perhaps a “shared node”?).

Indeed some nodes’ icon get preserved !
Like time1 lambert1 shaderGlow1, also their UUID didn’t change, too.
( another Maya Fun Fact I guess )

install a callback for scene-open

I was going to do this.
It’s really a bit unfortunate that won’t survive scene-new/open, but since my original goal was only to differentiate between native objectSet node and those created from my pipeline (Avalon), I can sleep well with this outcome :D
Way better then using AssetNode just for custom icon (I was looking in that direction before this).

Lastly, thanks for having a look !
