As a random uneducated guess: Do you have the 16-bit Bloom performance option enabled by chance?

it would be fantastic if the suns could not emit shadows.I doubt they'd implement something so physically incorrect.
You guys are the most consistently active / interactive devs I have ever witnessed. Literally nothing to say sorry for :]sorry, it took us a bit longer than expected to test this build
SairesArtYes, I'm an AMD guy since forever :]
Did you setup AMD config? They really have magic working fast on faster RAM also RAM slot have similar magic what half speed ram clock if you wrong place in modules slot
Using only 2 RAM modules will basically half it's performance.It will half it's maximum theoretical bandwidth, nothing more.
faster ram will prepare the scene fasterNo. RAM speed is not the bottleneck in scene parsing / preperation. Your CPU is the sole bottleneck during scene parsing.
two 8Gb Ram sticks on a CPU with 4 diesThis has nothing to do with each other. As long as RAM sticks are not an uneven number, which would prevent proper use of dual channel ram, such relationships don't matter.
more powerful manipulation tools natively than Max ever did :)It would be funny if it wasn't so painfully true :/
I'm pretty sure it's limestone or maybe shell limestone. If you google limestone you'll get many very similar results.I think we are deceived by two different textures in the scene.
CPU utilization is at 100% during all stages of rendering.[OTrant]
I was wondering if anyone here could help me out with a fan issue I'm having.You want a smooth Fan curve and often the BIOS settings are beyond bad for that. Fan control in the BIOS is always limited. Although according to this post you have in your MSI Bios more advanced settings, MSI provides a companion APP, the MSI Command Center, where you can set a proper fan curve, which you can download here. Personally I recommend SpeedFan for that, as it is the pinnacle of Fan control software both in it's lightweight nature and detailed control. Unfortunately younger Motherboards changed the way they do FanControl and SpeedFan, which is not in active development does not detect the fan controls, but you can give it a try. Sadly you don't get direct access to fans anymore, a regression from previous generations of Motherboards. I'm sad to have to chose between the Heavyweight Asus AI Suite and proper fan control that doesn't suck on my workstation. All these new softwares STILL can't do exponential fan curves, like SpeedFan does for so long... Locking fan control behind OEM Software is such a disaster....
Why is my CPU temperature higher/fan louder during the denoising compared to the rendering?Also it's heavy on the FPU, which is a nice heater element for the colder months.
The memory access pattern of the rendering code is very random - for example, each ray may hit a completely different object. This makes it very hard for the CPU to predict which parts of the memory will be accessed next, and in the end the CPU ends up waiting for data to be fetched from memory most of the time.
When the image is denoised, it is accessed sequentially one pixel at a time. Also the processing of each pixel takes long enough so that the CPU is able to read the next pixel from memory before it is needed. This is a best case scenario for the CPU - it does not have to wait for memory, and the execution units are (almost) fully utilized.
When the execution units sit idle waiting for memory, the CPU is able to optimize its energy consumption (and therefore heat generation), but when the denoising kicks in, the CPU units are kept busy all the time and so the temperature goes up.
actually the rendering itself is much more ALU/general instructions heavy than denoising, denoising is hardcore FPU stuff. I think it has more to do with the fact that there are no cache misses and branch mispredictions in denoising, since the workload is fairly simple and predictable. CPU does not have to wait for pipeline to repopulate after branch misprediction, or for data to be loaded from RAM, so the FPUs are utilized much better.
Cheers, sounds like a good work-aroundNo need for Photoshop trickery.
I put the ship on a white shiny plane in order to get the reflections, but now I can't find a way to tell corona to render this as transparent...The Corona ShadowCatcher is exactly made for this purpose. Though I'm on 3dsMax, I'm sure it's the same for C4D.
on an object with "flat" meshWhat does that mean?
