Hi guys,
I try to fetch my `usdrender_rop` LOP from my stage to a TOP network, to make wedges and montage, I have done the same without using the LOPs but this time its bit more confusing. i can see my wedges work fine it gets rendered but after the `fetch TOP` which is fetching the `usdrender` the output attribute is gone missing so its failing to generate the montage. I can do it after the render by using file pattern but i want this do be done automatically once the render is done.
without me doing one more step after render completes, after all that is why im using TOPs here.
Any help please




Thanks

Solved it myself

Here is the solution

when rendering in LOPS using karma there is two nodes when you drop a karma render

### Im assigning some variables here to use later
A = Karma Render Settings LOP
B = USD Render ROP LOP

When you set the output file path on A and fetch B into TOP network then the output attribute is lost, i think this is because that Fetch TOP is just searching for a `output` parm in B which is empty by default.

So to solve this I just added the output image path in the `Override Output Image` parameter and my fetch TOP was able to generate the Output attribute then the downstream TOP nodes can make use of it.

Hope it might help someone who might face the same problem, or alteast for future version of myself.

Thanks.
