Hi, I don't know what happened, but my renders just went to hell at one point.

The scene was rendering fine until I opened the project one day, and this happened. Sometimes I could get around it with interactive rendering, but recently even that failed.
All my geometry seems to be gone in all but one camera. The render takes a bit to compile geometry, but then the render takes 5sec.
Normal rendering mode shows me the HDR background and nothing more.

Any ideas?

Thanks

Hi,

Did you check the obvious - see if clipping panes are enabled in affected cameras?
I'm not Corona Team member. Everything i say, is my personal opinion only.

They are off.

This just started happening at one point. I didn't change any camera settings.

Is there any change after Render Setup > Scene > Reset settings?

I've reset the settings to no avail.

@Philip Kelly
If it were the doggy pints the scene wouldn't render fine so far.

Have you tried merging everything on a new scene?

I dragged a selection box around everything and saved it to a new file.

Still no luck

Is it possible to upload an archive of the scene for us to investigate it?

Thank you, much appreciated. One last thing, are you getting any errors on Corona error log when rendering?

Just some basic stuff like "in your proxy there were some flip normals and we fixed it automatically."

Sometimes the scene renders fine and then all of a sudden just all the geometry becomes invisible and I can only see the corona sky in the background. Sometimes switching to perspective helps, or creating a new camera deas the trick.

Yesterday it took me half a day and fury starts just to have the same render same file no changes is just works or doesn't at random

Hi,

What's the specification of your PC? On our system the scene took 95+gb of RAM to render, could you be running out of memory?

Also, I didn't notice which version of Corona and 3ds Max you are using. Could you clarify?

Thanks,

Rowan

Yeah, I know it's big.
It's a wedding, and lots of table proxy and plants are scattered around. Plus, it's a glass marque, so you need to see the park area around.

My 5950x ran at 30% because the virtualised RAM couldn't feed it data fast enough.

I've got 64GB of 3200 RAM, and Corona said it needs to virtualise another 120GB.

I don't think it's a matter of RAM though, as I managed to push through the problems in the end.
The renders seemed to work for the live preview some of the time, and some of the time, I had to switch to the production render.

I can't say I noticed a pattern to it. I rendered two views and then it would freak out. Another day I couldn't get one going.

The two attached visuals were really troublesome, despite using Corona scatter's "limit to viable area" option.

Hi,

So in this case it's a little difficult for us to diagnose the issue. We tried rendering this scene on one of our machines with plenty of RAM and it rendered just fine.

Weird stuff like this can definately happen when you run low on RAM during rendering. To be honest I am surprised that it didn't crash.

Can you provide which 3ds max and Corona versions you are using, so we can try on the same versions here just to make sure.

Corona Scatter doesn't have a "limit to area" option yet. I assume you are using ForestPack?

Sorry, you're right that was Forest pack :)

I'm on MAX 2020, with Corona 7 from 11 Aug 2021

Hi,

We'll try to render the scene again in these versions of Corona and 3ds Max. But I would bet the issue is caused by the system running out of RAM.

I'll let you know our findings, otherwise the only things I can suggest are either simplifying the scene or upgrading your RAM..

Sorry to not have better news.
