Hires COP maps crashing

[psanitra]

Hi

I`m generating vector displace map for ocean on COP and applying to single plane for render. It works up to certain size , let`s say 8/10k Resolution(attached image), but it will crash with 16k for example. Map itself is generated fine and can be viewed in COP. I don`t think memory is the issue, at time of crash it only ask for 30GB at edge length 1 and 9GB at edge length 4, i have 128GB. HIP file attached

Hello psanitra, can you be mroe specific about V-Ray and Houdini versions. I've tried on my side with 16k displacement map from COP of the OceanEvaluate SOP and it renders fine even with 32GB ram. I am with last nightly build of V-Ray on H17.5.327.

chakarov 17.5.327 on W10, and build was vray_adv_41203_houdini17.5.293_29c900e_4988_window s.zip . Did you tested it from the HIP file i attached or fresh?

[chakarov]

Sorry, I didn't see the file, will test it and will write back.

chakarov I just tried todays version Build number: 5062 hash: a09b991 from 03 Sep 2019 on the same HIP i sent earlier just open and render and it crashes same way - 16872: Fatal error: Segmentation fault

Hey psanitra, how did you get ocean displace to COPs?
By the way, is this problem solved?
Best,
Doca

Hello @docami, the issue should be fixed some time ago.
