I’m rendering some archvis at the moment, couple of tree proxies, vraysun+sky, physcam and grass with displacement.
When I try yo render the scene with all the bells and whistles enabled - it crashes. When I disable displacement - all is OK. When I hide the proxies - all is OK.
Memory usage without displacement - about 650 megs.
With displ - …2,4 gigs :shock:
I think this can be a memory issue, but I’m not sure…
vraylog gives me this:
error: UNHANDLED EXCEPTION: Irradiance map thread
Last marker is at .\src\displacementfunc.cpp, line 196: Done evaluating displacement function
…and then CTD
:?
also the crash is resolution dependent - below 1024x576 all is fine, above - CTD.
I’m on 32bit max 9, xp pro 32, 4gigs/3GB switch, vray 1.5sp1
Under the Vray:System rollout, change the “dynamic memory limit” from the default 400MB to 3000MB. Even with default geoemtry set to static, displacement and vray proxies use dynamic memory.
If this doesn’t work, are you using 2d or 3d displacement for your grass?
ah, it is your edge length. If 2d doesn’t work for you, up it to around 8 and then just lower until it starts crashing. Edge length is resolution dependant so it typically starts causing a lot more memory problems at higher resolutions.
PS. We use 2d displacement for grass typically with great results and less memory overhead.
3000 MB is way to much for a 32-bit machine; you should use a lower value like 1000 or 1500 MB, or even less, depending on how much RAM is used for other things as well.
