Next Update 3: Crash after canceling or finishing a render

[yavor.rubenov]

Ok, so far I've found a temporary workaround - open the scene, switch to scanline (this will loose the settings so save some preset maybe) and save the scene. Then close Max, open it again and open the scene with scanline. Then switch back to V-Ray and save - the scene should work correctly now.

The actual issue is somewhere in the VFB settings V-Ray saved in the scene - when we load them something goes wrong and somehow messes up the Max Bitmap Manager. Those messed up settings only happen in some V-Ray versions - the newest version should save the settings correctly.

I now have to find what setting is actually messed up and how to read it correctly.

Actually I was wrong it might not be related to the saved settings. Do you use the test resolution toggle in the VFB? If so - do you get crashes if you don't use it at all for the whole Max session ?

I did not use the test resolution settings at all after we upgraded to Update 3. In all the sessions I had, I did not use it and still experienced crashes. These were random though, sometimes the render finished or canceled without issues.

However, I can not guarantee that one of my colleagues used test settings button before I took over, so maybe something got messed up the first time it was used?

In the meantime, disabling the viewport background image seems to help, but this can only be seen as a temporary fix. We will have to use the viewport background in the not so distant future...

Alright, so here is another minidump and logfiles for another crash that happened today. Not after finishing or canceling a render, but simply by opening the material editor. This is getting worse!

Could you try the latest stable nightly (29754) - we've added a fix that we hope will help.

Thank you, I will try this.

The nightly from 23th December seems to have resolved the issue, it did not happen again so far.

Good to hear.
