  • Newbie question Phoenix crashes 3DS during Embree stage of rendering (out of memory)

    Right off the bat I'll say I'm a Phoenix novice and having to use it for the first time without having gone through the complete learning process of creating a simulation simply because I am having to pick up this project from someone else (who has since left working with me).

    Our project is a ship in the sea.

    The previous Visualiser used Phoenix to create a sea / wave simulation (a single still image) for a render that was created at 2560x1440pixels (I don't know if that's important).

    That scene renders out at 2560px no problem - I've done that and it works.

    But I need to re-render the scene at 5000px longest edge.

    Do I need to recreate the simulation for that new render resolution ?

    My computer has 64Gb of ram, when I render, the scene, my computer bombs out of 3DS Max during the Embree stage of rendering (task manager shows Physical Memory getting gobbled up during the Embree stage of rendering and down to around 4gb before 3DS Max simply vanishes off the screen and disappears from "Services" etc in Task Manager).

    If I uncheck Embree, the render at 5000px happens but does render correctly, i.e. I get only some geometry rendered (out at 5000px) and the rest of the image is black......

    I don't understand enough about Phoenix at this stage, but am wondering what could be the problem and indeed do I need to re-create the Phoenix Simulation for this new, larger resolution ? Or can I use the already created simulation that was done at 2560 ?

    Any answers would be gratefully received (as soon as possible please ).

    Many thanks.

    I tried rendering with Embree checked at 4000px, still got a failure.

    Tried rendering at 3500px and it's going through the rendering now (so fingers crossed, we should be okay at 3500px).

    But please, can someone enlighten me as to what might be the issue ?

    Thanks.

      Is is possible to send us the scene so we can check it out? Sounds like something is not right.

      You can send the scene to support@chaosgroup.com with a link to this thread.

      As for the simulation - if it looks good when you render it at bigger resolution there is no need to resimulate. Use the already simulated one if you're satisfied with the quality.

        Hi Georgi,

        Of course, I'll send it to you in the next 10-15mins.

        Though of course, I can only send you the Scene without a simulation ? (those take up 36gb).

        Let me know it that will still be enough.

        Many thanks.

          If you can attach a single cache file as well that would be helpful. Just attach the one from the frame that troubles you.

            Hi Georgi,

            Sent you a WeTransfer with the single cache file (for frame 470).

            Many thanks.

              Guys, please can you confirm that you've received / not received the WeTransfer ? I've received no confirmation that any download by yourselves has taken place.

              Thanks.

                  Looks like there are two bugs in here. Rendering with embree shouldn't crash even if you run out of memory.

                  The other thing is that the ocean is gone if the resolution is pretty high.

                  I have logged them in our bug tracker and I will update the thread when we have something on that.

                  Thank you.
