![]() With progressive usually you can stop the render whenever you feel the image is clean enough (and maybe having the denoiser updating every few minutes until you like the result). You can set a time limit for your render, but this is probably more useful for animation rendering. On the other hand, advantages of progressive mode, ![]() For things like high frequency details in bump mapping, you will be able to see the final result faster and you can make the buckets follow your mouse, while with progressive Vray will need much more time before you see the final look of your bump mapping uses less system RAM specially with high res renders, as the data gets stored directly on your hard drive, while in progressive everything is kept in system memory until the render finishes supports more features like Cryptomatte, Resumable rendering, Anti-Aliased render elements. Works better with DR rendering, consuming less network traffic So bucket mode will stress your CPU more than progressive, same for your GPUs if you are using Next GPU ![]() For Cycles or RS, you have to use Bucket.īack to advantages of bucket mode in Vray, They are terribly slow with progressive mode and they have big limitations so things will look different. Like I said, this is not the case with other renderers that offer bucket/progressive options. ![]() But unlike other renderers, Vray is still extremely fast in progressive mode I find myself using it in some situations. I've also tested this in other renderers(Cycles4D/Redshift) and likewise, bucket mode has been always faster. I've never seen a case where progressive has been faster than Bucket. Probably the reason behind this speed difference is that for Bucket mode it is easier for Vray to determine the right amount of samples, while for progressive, Vray will add more and more samples adaptively. In my testing I've seen bucket mode being faster by 15% (making sure both renders are as clean) Bucket mode is very good in cleaning noise, so comparing it to progressive you will have to use lower noise threshold, to match how clean it is compared to bucket.ĭifference in speed is scene dependent. ![]() Progressive and bucket produce different noise patterns, so comparing them you shouldn't rely on using the same noise threshold. Bucket mode has been always faster than progressive and it gives you cleaner results with the same noise threshold. There are situations that progressive can be very useful, but for majority of my stills I use bucket mode, here is why Are the consensus, for final renderings stills, Bucket rendering is faster and the way to go?Both of them has advantages and disadvantages. ![]()
