Displacement Crash

[Guillermo Leal]

I'm working on a large interior with lots of displacement, up until build 2015-10-09 it works fine but on build 14 and 17 max crashes if using displacement. if its off it renders fine.

i have not been able to narrow it more. i will let you know if i find more information.  for now i have move back to build 09

using Max 2016

Please upload crashed 3ds max session's minidump file.

How to report issues?

[Guillermo Leal]

i reinstalled the 17 build so i can send the dump file, but it did not crash, but the render is all black now!. i'm going back to version 09. i will try it in a few days once i have some free time.

Hey,

can I have the scene?

Thanks, Robin

Because you mention render is black:
could it be that you are running out of Ram? If that is the case, disable all the render elements and try rendering with PT + PT

[Guillermo Leal]

Robin:
sorry i cant share the project.

Belly:
not running out of ram, its using 42 out of 64. it hasn't crash anymore but it renders black unless i turn off displacement then it renders fine. maybe when it crashed i did ran out of ram, i might have had another session of max running, not sure.

same scene without touching anything i can open it in daily 2015-10-09 and renders perfect.  something was changed after that release regarding displacement.

OK, if you should run out of memory with 64 Gb, it must be a hell of a scene. :-o

[Guillermo Leal]

here is a simple Max 2016 scene where it happens.

below are the renders with the modifier on-off, with daily build 2015-10-09 renders fine, after that it renders black

ok, thanks for the scene. We can reproduce it now, should be an easy fix, we will do it tomorrow

[Guillermo Leal]

Excellent, thanks

[Ondra]

Fixed

[Guillermo Leal]

Nice, when are you planing on posting the update?

thanks,

[Ondra]

there will be probably daily build in the evening, so few hours
