Working with large scenes

in Technical Help (nuts n bolts)

Hi,

in my current project I‘ve got a very lage scene (memory wise). I have prepared multiple files which I try to merge into one, but during merging, DAZ crashes. Scene contains 3 G3, 1 G8 and 6 G2 (with lamh, each around 250MB on disk). My computer has 32GB memory, DAZ utilizes around 12GB before crash, rest is “free”.

i don’t want to edit anymore (don’t have viewport visible), only merge and render...

Do you have any advise how to cope with such a scene?

thanks & best regards,

   Peter

    Is the LaMH hair there as such, or has it been converted to geometry for use in Iray?

    The green LAMH geometry is "visible" as well as the toOBJ converted object. I've set the viewport to boundingbox but I'm not working on the viewport: I have the rendering settings-tab in front...

    If you have the OBJ version of the LaMH models then those are going to be large.

    I've noticed this already on file size... But should lamh models impact or cause a crash in DAZ Studio (when there's still plenty of memory available) ? How to workaround this issue?

    What Windows version are you using as there is a limit to how much each one can use no matter how much you have fitted in your machine?

    I‘m on a 64bit system using a 64bit compliant Win 10 Pro.

    Mem wise i‘ve seen utilization upto 28 GB (e.g. during an iray cpu rendering) without issues.

    ... could it be that for opengl viewport rendering DAZ tries to load everything into the GPU? There my limit would be 8 GB... 

    is there a way to check the logs if this was the case?

    Is it when you merge the LAMH image into the scene with the other files loaded that causes the crash? If it is, does it crash if you load that scene first and then merge the others?

    Try to break the scene into pieces that can be rendered seperately?

    If your light and shadows allow, it may be easier to render parts of the scene and then combine them in layers using a tool like Photoshop or GIMP rather than trying to render the whole thing at once.

    No matter how I merge the scenes, it always breaks when loading the 5th lamh geometry.... (anyone had success having 6 G2 chimps with lamh in a scene?)

    i think was already thinking if I can render without lamh objects first and render them individually and photoshop everything together... as it’s only hair and as Hair doesn’t hugely impact other scene objects, it should be possible without degradation of thre scene itself... (but somehow defeats the purpose of rendering the scene...

    Perhaps if you send the hair to hexagon after creating and posing, then decimate it to lower the poly count?
