Slow "Loading bitmaps and updating object"

[Morbid Angel]

Just a wild one, but bitmap pager is off? (Vray should disable it by default now but perhaps its not working?)

[luminancestudio]

@Morbid, yes, the bitmap pager is off.

Try turning Embree off. I seem to have found some relief with that. But I also rebuilt my scene, so I'm not sure at this point what actually helped.

Also, do you have any Forest Pro or RailClone objects in your scene?

[PIXELBOX_SRO]

no forrest, no railclone, no displacement, no dynamic objects, really nothing special

[PIXELBOX_SRO]

remerging scene doesnt help

OK, I'll send the scene. Couple things I have noticed...Every time I switch camera's it take 5 or 6 minutes to Load Bitmaps, then another 3 or 4 minutes to create the Light Cache (I'm using Brute Force/Light Cache) after that first rendering with that camera, it renders much faster with subsequent renderings from that camera. No more 5 or 6 minutes to Load Bitmaps and Light Cache takes 15 or 20 seconds. However if I change to a different camera in the scene, I get the long Load Bitmaps and long Light Cache creation again. Another thing is the Low Thread Priority is not being honored during this time so my computer is basically useless for 10 or more minutes while Loading Bitmaps and creating Light Cache even though I have a 40 core PC.

Hello

Did ChaosGroup find the cause of this problem?

trouble with the same case.

It is displayed when rendering the old V-Ray scene (3.4) with V-Ray 3.5/3.6.

[Morbid Angel]

flat I can take a look do you have the scene somewhere?

Hello Dmitry.

I was a local reseller of V-Ray and received consultation from the customer about the same problem.
Customers can not give scenes with NDA.

I would like to ask if support of ChaosGroup knows the solution.

[vlado]

You could try converting the Bitmap textures to VRayHDRI textures using the V-Ray bitmap to VRayHDRI converter script - that's the only thing I can think of.
