Increased memory usage: GPU rendering: VRAM | CPU rendering: RAM | Hybrid rendering: VRAM

When you hit render with Persistent Data, it looks magic cause it starts instant. Blew my mind

Awesome - I'm looking forward to this feature. Thanks for sharing

Hi, it's a nice feature BUT I recommend to check this feature just before the final render ! BECAUSE I experienced that, if it's 'ON', and you render some stills while working on the scene and you change for example the world HDRI, you won't see an update in the next still renders UNTIL you change something in the render settings, to force the cache to rebuild.

So beware of, that the cache isn't useful, when still doing test renderings.

I feel like this button has been in Blender for years and just hasn't done a thing. This is great

[SeanyKrabs]

Yes! I've been waiting so long for that!

Nice information, thank you Blender Dialy. :)

Thanks!!! Unfortunately just day before i was rendering animation and scene build time took so many time, but now i will use this feature.

[clausbohm]

Wow, that's a new one! I use "Fast GI Approximation" and works well too.

Amazing, thanks for sharing this feature.

[SportzCar]

For my opinion... This is super useful for rendering Eevee.

[pxrposewithnopurpose]

we really needed it cause thei fking hate updating shader

Sounds great, why wouldnt this feature be on permanently? Even if its off, rendering a frame would use the same amount of memory to calculate the scene for a frame, wouldnt it?
So if its on, its going to use the memory also, but just calculate it once right?
