I just got off a feature and used Arnold for the first time in a larger scale production and my lord, the way it handles light and it’s ease at creating setups to easily match backplates made it an absolute joy to use. I never Imagined it being something I would use for rendering. Funny enough, I only got the 3990x because Houdini scales nicely for many of it’s sims with more cores. ![]() Once prices come back down for the 3990x I plan on ditching these 3090s for two more 64 core 3990X based setups. Nodes mind you that have a total of 8 x 3090s. This has me reconsidering CPU rendering and says volumes about how impressed I am with Arnold as I’m now considering ditching my two GPU based render nodes. That said, my primary workstation has a 3990x 64 core CPU and I have found it to be about 25% of the speed of an RTX 3090 which given the quality and time savings I experience during look dev and scene development with Arnold is worth it, especially if I have jobs with a little breathing room on the deadline. Only AA is only supported with adaptive sampling in GPU mode ATM. Unfortunately, Arnold’s GPU counterpart still is missing some important features such as trace sets and better control over where samples are going. I tried out Arnold and was completely blown away with how beautiful the final frame look with a minimum of fuss. I knew Arnold had a great reputation but had not considered it as it was CPU based and at that time I couldn’t imagine going back to CPU rendering. Then last year as Arnold GPU started to gain parity with its CPU counterpart I gave it a look for the first time. I had been using Octane for almost 8 years and switched to Redshift about 5 years ago as more of my Agency clients were integrating RS into their production pipeline. Of course all this becomes a no contest when you simply cannot get hold of the latest cards and second hand ones are likely to be well hammered. Ideally I would use a combination of RS and Arnold !! I do have issues with some anti alias features on geometry with Arnold, RS renders beautiful smooth images but I think that is a learning curve. Now for look dev I could use the GPU’s on Arnold, it is still too flaky for finals but when it stays stable it does give great GPU renders. The ONLY reason i lean towards Redshift is the speed at which I can knock out ‘OK’ renders…but I want more than ‘OK’…if it’s good enough…it isn’t. Hard drives and very rarely power supplies are what tends to die and again that is very rare.Īrnold is FAR easier to configure and use, give stunningly beautiful renders, and has no issues bailing out due to lack of memory. The chances of several components breaking on a CPU rig are slim and I have NEVER had a CPU fail - famous last words- nor RAM for that matter. With RS if your card goes down your rendering ceases and you need to lay out for a new card. Add that to what i already have and I now get at least 9x my render speed.Īnother advantage is wear and tear. The price ? I would imagine I could build a box for under £2000. Now if I bought or built a new 32 core Threadripper box and added one of the cards to that, and used a bog standard cheapo card for the Xeon which I have laying around, I will get a machine that would be at least 6 x faster than my I7…faster CPU’s faster Ram, better motherboard etc. The draw on my power supply will ramp up and at 650 W i am not sure if it will handle it though the Xeon rig would having 1000w+ power supplies I could probably get the 2 x 1070’s for around £1000. Now forgetting the Xeons if I wanted to double my render speed using RS I would probably have to add at least 2x 1070 cards or maybe one 3080 though I doubt very much if a 3080 is = to a 1070 and a Titan. I have a dual xeon as a render slave which renders out at roughly twice the speed of the I7. Now my cards are very low level in today’s world, a 1070 8 GB and a Titan 12 GB on my I7 3730 6 core. It also has the added advantage of loading bcfs much faster than RS thus doing away with the need to do the arduous conversion ( a point that becomes mute with Reactions) Redshift IS fast but from what I have experienced the TFD render quality is just not up to Arnold, it takes longer, far longer to tweak and get the settings that give the look that approaches the quality of Arnold…and it is not that much faster than Arnold on TFD VDB’s. ![]()
