Scene parsing issues

Hi Guys,

I have 2 problem when rendering now. The first is after i press render, corona parses the scene, and when it's done corona just stops (Smiley face stops spinning) and the current task popup disappears. In the VFB the render button is greyed out and it cannot be stopped.

The second problem is after pressing render, as corona parses the scene, it gets stuck. it doesn't go past to the next task. it can stay in the parse scene task for hours. until i click on 3ds max and it finishes parse, secondary GI and goes immediately to start the passes as if nothing was wrong. It doesn't happen all the time but frequent enough to be ridiculous. Imagine having to sit in front of a computer as it renders an animation to make sure it doesn't get stuck parsing one of the frames.

anybody have a clue what's going on here?

Hi, which version of 3ds Max and Corona are you using? Are you using any 3rd party plugins in your scene? What is your RAM usage after the rendering is started?

I have some more questions:

Can you please explain what exactly you mean by "current task popup"? Can you share a screenshot of this?

When it is stuck like this, please capture 2-3 minidump files and send them to us. Here is a guide explaining how to do it (see point 2):

Hi Maru,

I'm using Max 2022 and Corona 7 Hotfix 1. Yes i'm using alot of plugins. RAM Usage is in the low 60s

I've added a screenshot of the rendering popup i meant. That disappears when parse scene task completes.

It may be because i clicked outside of max (on a browser or another app) but it sometimes happen when i have nothing on apart from max.
I'll send you the minidump file next time it happens.

In regard to your second problem, the same thing has been happening to me. At first, I was wondering why parsing was taking forever, then I clicked into the 3dsMax window and the parsing progress bar completed in seconds. I'm not really sure what causes it. It doesn't happen all the time, but often enough that I have to keep an eye on the screen to make sure it doesn't get held up.

Hi all, I'm also using Corona 7 Hotfix 1 and also encounter the scene parsing issue Andrew and John describe. To me it seems to have to do something with Forest Pack and/or Railclone, but I'm not sure.

In some other topics on this forum I read a similar issue is fixed in the latest Daily Build of Corona 8. Is it possible to 'back-port' the solution to Corona 7?
