I remain fully at your disposal for any information you need, It's also might be something to see with EPHERE, not sure about it. Vray GPU 5, update 2.2 up to date and some recent test with the nighly VRAY adv 52020 max201 With Ornatrix Alembic import (we can't use that pipeline in our project because it crash when he try to convert ABC into spline with some specific grooming just before rendering)
With native Ornatrix hair (we can't use that pipeline in our project, we need to use and intermediate export option)
In Vray CPU (with all the same settings) Severals builds from all the software, as many options in the Ornatrix ABC export and the VrayProxy import as we could.Įvery single option we could in VRAY GPU, Brute force, Light cache, Bucket, Progressive etc. The only way to restart fresh is to reboot 3DSMAX to clear the VRAM cache, and launch the render were you left it. Obviously after somes frames rendered you ran out of VRAM. It seems VRAY GPU can't clear the previous VRAM hair cache and stack the new one on the top of the previous cache.Įven if you stop the render, the VRAM hair cache don't clean.Įven if you start an new render without rebooting 3DSMAX, the VRAM hair still can't clear itself. Linked two snapshot of two differents frame (of the same scene, with the same grooming, without any animation in the grooming) Our grooming is made in 3DSMAX Ornatrix, exported in Ornatrix ABC, imported in 3DSMAX in Vrayproxy.Īt rendering time, in Vray GPU, for a image sequence, each new frame calculated with the same computer stack a new amount of VRAM cost for the hair even if the is no animation on the grooming After some intenses tests we are facing an issue with Vray GPU and Ornatrix.
