So this is a tricky one that I've been battling with for a few weeks and wanted to bounce some ideas off people here at Chaos. PM me for files and I will package and upload as I can't release these into the wild.
Let me set the stage - these happens on very large files, we are talking 20m edges, 80k components instances, 20k component definitions, 15k groups, etc etc. Huge urban development projects with multiple buildings (from Revit, but thats not the issue - stay tuned), cars as vrmesh proxies, people as vrmesh proxies, and trees as vrmesh proxies. With everything on, I get various forms of the c0000005 error and only part of the model renders (it will be full frame, but entire buildings or ground planes are missing).
If I delete the vrmesh proxies, everything renders fine.
If I delete everything BUT the vrmesh proxies, everything renders fine.
If I make the buildings as vrscene proxies and keep the vrmesh proxies, error.
Basically, I can have everything in the scene as a proxy, error.
Usually the error happens after/during the light cache process, so I tried BF/BF or IM/LC, but error.
On a whim, it seemed like the error happened after it processed vrmesh proxies, so I swapped out all vrmesh proxies with vrscene proxies, purged, and the scene worked fine.
I also tried an option where I replaced all my vrmesh proxies with Cosmos proxies, purged, and the scene rendered fine.
So I'm leaning toward these vrmesh proxies being the issue. They were made in early vray next / late vray3 days, on skp 2019 (but BEFORE you could "attach" the materials to the vrmesh). I'm going to try going back to the original purchased meshes and recreate proxies, though it makes me wonder if I should be using vrscene's for more reliable long term use and interoperability with other programs.
Code:
esh file "M:\vrmesh\02 VEHICLES\CARS-TAXI\toyota prius.vrmesh" linked successfully.Mesh file "M:\vrmesh\05 PEOPLE\SITTING\RIGGED_SITTING_ani_CBoy0004_M4_0002 6.vrmesh" linked successfully.Mesh file "M:\vrmesh\05 PEOPLE\SITTING\BMan0201-HD2-O02P02-S var00003.vrmesh" linked successfully.Exception in CORE: Unhandled exception c0000005
