Corona IR keeps freezing and crashing max

[3dboomerang]

Hi, we're currently experiencing a 100% guarantee on max freezing when using the IR. The scene just hangs. Need to force shutdown, all work is lost. So we are in a pickle.

Max 2021, last update
Corona 5 hotfix 2
Windows 10

Hi,

Is it one specific scene, or is it all scenes?

If it is just one scene are you able to provide it? And can you describe exactly what you are doing when the IR freezes?

Thanks,

Happens when using the sliders. When inserting numeric values, all good. When sliding > crash. Happens in heavy scenes. Just started a new project, scene is still less then 100K poly's, no Forest Packs or anything yet, just geometry, works so far. But IR still tends to hang when for example rotating the daylight compass with the HDRI-environment map linked to it (RadToDeg Z_Rotation / 360.0 through parameter wiring) - Almost like he needs to reload the hdri every +/- 30° degrees of rotation.

Just saying, the IR is not a "trusted" tool atm.. To unstable in our heavier scenes, and not handy enough for lighting, it's faster to do a normal render and pressing F9.

Hi,

I guess the only way we can look into this is if you can provide one of your scenes? The we can investigate the root cause of the freezes and look into fixing them.

There are some features known to cause crashes in certain cases. One is Substance as far as I remember crashing during interactive render.

Crashes during slider movement is something I do experience often on certain scenes, but I can assure you it is not specific to Corona. I heve most frequently had it with Max 2018, when Mental Ray was my renderer of choice.
3dsmax itself has something to do with slider manipulation. The case has become so predictable that I forsee it just as I click one slider. :)

Thanks! Can you tell me the name of the file so I can find it in our system?

Hi,

I don't see it in our dropbox, maybe the upload failed.. Could you try again?

Sorry for all the hassle.
