What procedure works when open a file?

I have a trouble when open a file.

The more aovs I create, the more it takes time for opening a file.

I traced the logs during opening a file, and I got a result like below breifly

// Read 239 files in  77.8 seconds. //

mayaHasRenderSetup();

mayaHasRenderSetup();

mayaHasRenderSetup();  // it occurs 32639 times.

Total Time: 806.98

I think that calling "mayaHasRenderSetup()" makes time-loss after reading all references.

I find that isValidAOVNode in avos.py calls mayaHasRenderSetup commands,

AOVInterface.getAOVs() and AOVInterface.getAOVNodes() call isValidAOVNode function.

So I concluded that AOV nodes that included in the scene are related with time trouble.

I hope to know how to solve my problem.

Please post a repro scene, and can you say what versions of Maya and MtoA you are using?

Yes, I found out a reason for slowing down. It was createAliases() method in mtoa/aovs.py, so I changed that.

(It cuts down the file open time from 10 mins to 40 secs)

Hello,

a very similar issue, with scene being slowed down because of the AOV nodes, was adressed recently and will be included in a future release
