QUICK TIP: Saving the UHD Cache 

Glad you are enjoying Corona Renderer, thank you for the feedback! Tom

@@ChaosCorona yes. although it requires a huge amount of RAM. but its good enough. and the whole interactive render is amazing. keep it up

@@murtazarizvi368 Well, we optimized RAM usage in 5, and are doing so again (for textures) in 6, so we will keep improving RAM usage as well as everything else :) Thanks! Tom

@@ChaosCorona considering how heavy my scene was i am amazed it showed fast results.

@@murtazarizvi368 Great to hear! :) Thanks! Tom

For a simple scene with only camera movement, YES! You only need to precompute a single frame. Precomputing a frame in the middle would be optional. (eg: for animation with 100 frames calculate frame 50) Totally, in animations, the problem accrues when you stick with the: “Still frame (fast Precomputation)” Preset instead of using: “Animation (flicker-free)”. [ Performance >> UHD cache ] Tip: If there are moving objects or lights in your animation, the "safest" way would be to calculate UHD Cache from scratch for each frame.

More coming soon, we are working hard on these :) Thanks! Tom

Yaaay

You are welcome! Glad you found it useful!

@@ChaosCorona I have a problem with the Rander in the video format so do not show me the texture and corona materials, especially the metals. Please help me Note that I use Corona

@@hezilyacine56 Hi! Sorry, I don't understand your question - best thing is to post on our forums, where you can share images, screengrabs etc. to explain what you are trying to do. RU-vid comments are too limiting for providing proper support :( corona-renderer.com/forum/index.php?board=29.0

Hi! There are no tutorials except one, because nothing changes between rendering stills and animations (animations are just a series of stills, after all :) ). You can find the one relevant tutorial at coronarenderer.freshdesk.com/support/solutions/articles/5000515648-how-to-use-the-uhd-cache-for-animations-and-stills- - thanks! Tom

@@ChaosCorona OK, thank u

@@ChaosCorona also is it possible that corona renders the whole animation video directly, instead of taking for example 500 still images from corona to after effect to create the animation.

@@kevweomoraka307 That's dependent on the host software and what file formats it writes to, but it is a very bad idea - If there's a power cut, you lose the whole animation and have to start from scratch from the beginning of the render; if you want to change something in the middle of the scene, you have to render the whole animation from the beginning; if you discover that the video compression is too high and need to change it, you have to render the whole thing from the beginning again; and so on. Rendering to image sequence and compositing in post is VERY much recommended, I would never do it any other way, as it avoids all those problems. Compositing in post is easy if you are doing nothing but assembling an image sequence to video, and free too (if you use something like DaVinci Resolve, for example). Hope that helps! Tom

@@ChaosCorona OK i understand now , thank u so much for taking your time to explain this, I really appreciate .

Thank you for the kind words! If you want to save out animations you need to define a frame range in the 3ds Max render settings dialog. Animations are basically sequences of still images that you then put into a video editor and export as video files. RU-vid comments are typically not the best place to have long discussions though so if you have further question we'd recommend hoping on our forum and starting a thread there (forum.corona-renderer.com/).

@@ChaosCorona thank u so much, I have made it as you say!

@@salma2464 Glad you've got it going and thank you for the thanks! :) Nejc

Wow, a noise level of 20 is incredibly high, and the image will not be clean at that level (nor clean enough for any denoiser to work properly). Recommended noise levels for finals are between 2 and 5% (larger resolutions can use higher noise levels), or drafts from 6 to 8% noise. So 20% would leave a long way to go :) Thanks! Tom

@@ChaosCorona Hey Tom, thanks a lot for your reply. So, noise level is responsible for flickering in animations - from what I understand? I had hoped that checking the "flicker free"-box would eliminate flickering independently from the noise level for animations. Of course, 20% noise I only use for super-draft renders. Regards!

@@Musicsson Whew that noise level at 20% is just for super drafts :) The flicker free helps eliminate flicker where the UHD Cache may be calculated differently between one frame and the next, but has no effect on the noise as such (and if you have lots of noise, things will still flicker from frame to frame). So the checkbox will remove/reduce flickering in final renders, but not help any in drafts (best just to leave it off in drafts in fact, speeds up the UHD Cache calculation without it, and since you are going to get noise and flickering anyway...) Also, be sure to try out the 4K Cache in Corona Renderer 6, should be even less flickering and better results than the UHD Cache :) Thanks! Tom

@@ChaosCorona Wow, good to know that in drafts, "flicker-free" has actually no visible effect - and unchecked it speeds up the UHD. Thanks a lot for the info! Regards!

Hi! There are no performance changes for animation - animation is just a series of still images after all. So the same optimizations apply as you would use for stills, nothing different for animations other than what is covered in this video. Thanks! Tom

We've never made a tutorial for exteriors, as it has less need of optimization and set up - most of the topics, such as using scattering, or setting up an HDRI or Sky for lighting, are covered separately, and unlike interiors, there wouldn't be many specific tips, tricks, things to keep in mind etc. to discuss. Thanks! Tom

It's up to you on what range of frames you want to precompute the GI for - usually it would be for the entire animation, and set to skip to every 5th or 10th frame or something; but if things that change GI come to stop at some point in the animation, then you might just want to precompute the GI up to that frame in the animation. Hope this helps! Thanks! Tom

@@ChaosCorona So if my cam speed is slow then every 10th frame? will that work and no jitter/flicker?

@@CryptoFeeders It will all depend on the scene and how much the GI is changing per frame, but that sounds reasonable. Best bet is to do some short tests first and see if all is working well :) Cheers! Tom

Sorry, I don't know how "Camera path single frame calculation" works in V-Ray. For a moving camera, as the video says, you can do a run through the animation, set to just one pass so that all it does is calculate the GI, with the solver set to use Load + Append, plus Save after calculation, usually setting the renders to be done every 5th, 10th, 30th frame etc. rather than every frame. Then when you do the final animation, the Cache has the composite sampling from all along the camera path, and you don't need to use recalculate every frame. Thanks! Tom

CoronaRenderer understood. Thank you for writing in detail.

@@neels Most welcome! If you have further questions, you can always pop over to the forums where support, developers, and the community can help (and the forums allow things like sharing screen grabs etc. that can help ask or answer questions, unlike comments here on RU-vid). corona-renderer.com/forum/index.php for where to find that. And of course for true technical problems, you can always contact support directly too when totally stuck! Thanks! Tom

CoronaRenderer great, I shall do that next time.
