bitmaps loading every frame?

[super gnu]

i have a very fast rendering animation, like 5 secs a frame fast.. however it has a few 8k textures in it. i assumed they would be loaded once and then used every frame.. but no! it spends 3x longer loading the textures each frame than it does rendering.. is there a fix?

they are not animated in any way, although the object with them on is keyframed rotating.

I just came here to ask this - doing the same thing, using GPU to do a super fast animatic of a landscape with not much a few 8k textures and its frustrating seeing it load in between frames. Is there a way to keep it in memory?

[hermit.crab]

Currently no, the textures are loaded and unloaded on every frame.

We're working on resolving this, but at this point, it happens on every frame, yes

Hello! Was this ever fixed? Currently doing 1.5 minute frames on a vray SketchUp animation and this would save a lot of time!
Is it possible to get a 30 second simple animation batch rendered in the chaos cloud (in 1-2 hrs)? in a shorter period than it takes to make an animation with computer (1 day)

Hey jrozansky

Keeping resources between rendering animation frames is not possible at the moment. This is near the top of our current priority list
I will update the thread when there is news on the topic

About Chaos Cloud, it depends on the resolution and complexity of the scene. You can have 20 free credits to test with some frame and make a conclusion

Best,

What about bitmaps reloading each time you change something in your scene during IPR?

[Muhammed_Hamed]

Karol.Osinski This is not expected to happen, changing one map on its own shouldn't trigger everything to reupdate
Any steps to reproduce this ?

Thanks!

[Karol.Osinski]

It is not only happens when I change the map, but also when I move the sun around. Everything recomplies / reloads. It does not happen in every scene mind you, I still didn't find out what causes it.

Do you have any updates about this topic?
If it was near the top of the priority list over 1 year ago, you certainly could have made a progress.

It seems a function that could shave off a very substantial percent of the rendering time in many cases, especially with the animation with the lower resolution and quality settings (which both can be fixed in post production with de-noising and AI-based upscaling). In such cases loading the bitmaps with every frame takes close to 50%, so removing a need to re-load resources could easily make the render 2x faster...

Inicialization before render start is reallyteribly looooong in GPU rendering. When GPU is fast, inicialization makes it super slow.

[GregCooper]

To add to this, not certain but I’m pretty sure other render engines RS and Octane don’t have to reload every texture between frames with animated sequences. However they’re working, the time between frames seems much quicker. Vray GPU has pretty good render times these days once the render starts but the time to first pixel still seems like it needs a bunch of optimisation, particularly in animated sequences.
I sometimes find myself switching to my much slower cpu to render certain sequences simply for this reason

[Jiri.Matys]

Yeah, but I bought 4090 for rendering animations, to be fast. But when a lot of textures are in the scene, it is slower then cpu.

[LeePuznowski]

Yes please get this better optimized. This is bottlenecking many projects we're working on and causing render times to be many times slower than the actual rendering.

[squintnic]

its been 3 years since this was an issue - any updates?
encountered insane load times vs render times per frame making my GPU farm useless compared to CPU times.
