corona 1.7 interactive render problem (SLOW)

[Frenkkk]

i try  corona 1.7 but on my complex scene the interactive render don't work

interactive render always blak screen

1.6 version work fine in same scene

[Ryuu]

Could you share the scene with us for our internal testing/debugging?

[Frenkkk]

is a 600/700 mb scene with corona proxy and much more.

with corona 1.6.3  no problem, everything is faster and in real time

with corona 1.7 everything is slow, interactive render give a  black screen and only after many minute give a preview,
after the first preview, interactive work fine if only i move camera , if i modify the scene the interactive give black screeen again.


it seems there is a problem with load data in iteractive render.


now i reinstall corona 1.6.3 and all is ok.
with 1.7 is impossible for me to work.

p.s.
i was a similar problem with the fisrt version of corona 1.6

Same problem here...Interactive rendering crash all time, When I click in stop button 3d Max keeps thinking and then close it.
I can't work with your 1.7 final release, I have to downgrade to 1.6 version.

Best regards,

I have got black screens with interactive too. Old/new/simple/dense scenes.

As Ryuu asked, if that would be possible, please share your scenes with us:
https://corona-renderer.com/upload
Otherwise we may not be able to understand the source of the issue.

we have had the same issues. prior to 1.7 interactive was rendering fine with scenes with lots of grass and gardens (forest packs). preliminary troubleshooting suggests it has to do with the corona camera. when we switch to Max physical camera it takes the same amount of time to engage (roughly 90 seconds) but then works as expected (even though slowly). with corona cam it seems to go into a loop of trying to refreshing the whole time even if there is no movement (spinning windows circle). we can not recover max because you have to hit stop in the split second it refreshes so we have to end task.

I have attached a screenshot of the scene to give you an idea of what we are dealing with.

Hope that helps.

Hi,
what version of 3ds max do you use?

[Jacolath]

2017. i can see if I can replicate the problem in 2018?

Experienced the same black screen IR problem with a scene with 3Ml polys on 3dsmax 2018 + corona 1.7.

Hi,

I'd like to report the same problems with interactive rendering since updating to Corona 1.7, Max 2016.
It never took that long to load the scene into the IR window before. Now, I often have to wait couple of minutes until the image appears, even while working on small scenes.
During that time the IR window is either black or pixelised (see attached image).

Also not with IR, even with production render exist problem///
During production render process with resolution biggest than screen /1920-1080/ -for example 4k,
after some time VFB going to black, and only after switching between channels, for example from Alpha to Beauty or Lightmix a picture reappears, and after some time again disappears...
until the next switching channels:)

This should be already fixed in the latest daily build. Give it a try :)
