HtoA Houdini IPR Update Bug #68

Closed adrianmeyerart closed 5 years ago

adrianmeyerart commented 5 years ago

Hi, when I use Aton with Houdini the IPR Update in Houdini itself does not get updated. I image gets updated in Nuke correctly but the IPR in Houdini says "Generating Scene" and stays black after having started it over the Aton UI. Would be very nice to have the updated renderbuffer in both Apps! Is this a bug or am I missing something?

Thanks!

Win 10 Aton 1.3.5 Houdini 17.5.293 htoa-4.1.1_rf2c4e45_houdini-17.5.293 Arnold 5.3.1.1

Hi Adrien,

Sorry for late reply, it is expected as the output drivers are being changed to driver_aton. It would affect the performance if we just double them up, however it is easy enough to add it if you want to.

Add "+ outputs" at the end of the following line.

aton_outputs = [i.replace(driver_name, aton_name) for i in outputs if "variance_filter" not in i] + outputs

Cheers.

Hi, Thanks a lot! Could you roughly tell me what kind of performance impact this would have? It will not actually render twice I guess? Just output the renderbuffer two times right? So I would suppose the cost wouldn’t be to high?

Thanks again.

Yes it will affect mostly the first IPR iterations as usually they are running fast.

Thanks, worked like a charm
