Vray eats memory! // Bugs

Hi,
I found out that every rendering of the same scene with the same camera position decrease available RAM by some fixed for each scene amount. TS does not release this amount of used memory after rendering. For example in my test scene this add on is 130 MB and the figures of used RAM is 0.99GB - 1.12gb - 1.25gb -1.38 gb. The sequence finishes near 2 GB and TS restarting is required to release the memory and return to the initial figures.
Can anyone confirm this abnormal memory leakage in Vray 1.51 rendering?
TS 7.51, Vray 1.51, Win XP Pro, 4 GB Ram, Dual Xeon 3.4 |

What are the exact situation?
Are you rendering from Model or Workspace,
is Bridge on,
are you using Lightmap in GI (memory hogger),
using HDRI...
My current "Workspace only" project takes between 1-1.2 Gb when rendering...but I havn't noticed the things mentioned. :confused:
Though, I only check that it doesn't reach too high memory consumption...haven't checked if there's a steady increase.
Also, I constantly minimize the tS window which seems to clear the memory..?
(really curious as to what actually happens during minimize...) |

It'd be good to isolate exactly where this memory leak is, so any specifics you can give Changa would help out. A simple scene that can duplicate the results would be a huge help.
Tiles I think posted a similar problem as well.

What are the exact situation?
Model side rendering (and most probably also WS, but I vave no time to check it well), Bridge is off, GI and one Inf light, no light map, no HDRI. Background image/colour - does not matter. Monitored with Win task manager. |

I've tried now with a simple scene - coffee machine from TS model side library on the cube and with the same (above) settings. Rendering adds 2Mb each time. |

Ok, tried it with the coffemachine, Modelside, bridge ON (for Vray to work)
and yes... it seems to become 2Mb larger each render.
Also tried it on WorkSpace (since bridge can be OFF there) and it only adds 1Mb each render....so the bridge might have some influence.
And while in Workspace.... after a couple of renders I was up to
75Mb
Minimized window...and maximized again
34Mb
after first render
63Mb
after that same increments as above.
What exactly is cleared from memory during minimize!?!?
And couldn't that be done automatically after each render? |

Tried again with my current Workspace only, bridge off scene.
824000 polys. one texture 1000x1000 on 25 objects, and one 3000x3000 tex.
GI (no lightmap), but only a 640x480 render instead of my usual 5000x3536 ;)
528Mb -> 538Mb after render.
minimize, maximize ( I've added the VirtualMem column on win task mangr now, and it seems like that's where the stuff ends up.)
226Mb -> 238Mb after render ( VMem size increases with same factor.)
Looks like the increment is between 1-2% independant on scene size? |

Checked with Vray 1.52 - the same memory leakage plus fake shades from transparent shaders (I'll keep it for the next bug thread :) ) |

Ops, I only tried it with Vray1.52 ... at least it's consistent between versions ;) |
