If that were any more AI it would have 3 wheels, 4 fingers and a naked woman driving it.

ok, main thing here is that sometimes too much detail is a bad thing. Your displacement map is a 2000x4000 image which is fine, but youve told octane's displacement to use a resolution of 8000x8000. This means the displacement is going to start showing the lower resolution of the image in the geometry. Lower the resolution of the displacement to 4k or 2k, then on top of that add in 2-3 pixels of gaussian blur below to give it a little more chance at being smooth. Next you can bump up the AA filter size a little. The default is 1.2 pixels wide, youll be fine with 1.3 or 1.4 Then I actually lowered the reflection depth down from 32 to I think about 10. Your letters are reflecting each other, making reflections of reflections. This wouldnt be so bad, but... ... your glass is too perfect. With 0% roughness you dont have glass, you have the most pristine diamond in the world. Ive taken the greyscale displacement map and piped it into the roughness of the glass, this way only the lettering will get a slightly rougher/softer finish. Its then dialled way back by setting the mix value of the roughness channel to 0.02 so it only affects it very slightly. This gets me from here to here

post a scene file or send it privately if you need ( mash@3dfluff.com ) and I'll take a look. dont forget textures The cause of the dark strip will be a reflection of a reflection of the sky bouncing between the letters but that doesnt explain the jaggedness

Gregor did all the hard work for you, all thats left is for you to do is make an object rotate in a circle. With all due respect, if you're struggling to rotate an object then perhaps simulating the 4 dimensional fabric of spacetime isn't a task you should be attempting just yet.

Step 1: Uninstall Norton Step 2: Beer

Ok, nvlink is a bit more complicated than SLI. SLI is a simpler connector which syncs cards and is designed for using multiple gpus to render realtime frames in games. That tech is more or less dead, nobody uses it. NV link is more or less SLI v2. It allows for a more sophisticated sharing of resources between cards, ie pooling their available memory and fast data transfer between the 2 cards. It is possible your 3d render engine supports nvlink to access more memory and gain more speed, but it will be very driver and 3d app specific. Beyond that im afraid I cant help much as arnold gpu isnt the most widespread engine

Pull this out of both cards. It may be a solid pcb or a soft flexible cable.

DONT use SLI. SLI is purely for making old games run slightly faster, it does not make rendering faster in any way. Turn your machine off, remove the SLI bridge and just run the cards independently. Then in your arnold settings ensure both independent gpus are selected.

get ready to be told your power supply isnt good enough ;D

I have default settings, octane works exactly as expected. 1 2 3, pan zoom rotate

Maybe you turned it off in the prefs?

When you open a project a window pops up telling you the name of the missing font

Keep in mind redshift tends to run more slowly with cpu and gpu working at the same time. Usually its best to limit it to gpu only.

Not sure if it works in redshift, but the standard c4d render engine this would be the fresnel shader. Its just a camera-view based gradient. Try this, if not then have a look for a redshift native version.

Need to be a bit more specific. You want the gradient based on: The thickness of the object? The distance of the outer surface from the camera? If the above, then do you want the gradient to stick to the surface or should it change as the object gets closer and further away?

Go apply to be a beta tester. So long as there's a reasonable flow of usefulness from you; bug reports, ideas, feedback; you effectively get Maxon One for the entire duration. I haven't personally paid for c4d for 25 years now 😉 For a quick reference, and extrapolating back a little as the current database doesn't go back the whole 25 years, Im currently sitting on ~1700 bug reports, ~700 testing other people's bugs and 1100 ideas for features/changes. This is roughly one idea or bug every 3 days. Some of this will be small scraps like "The hitbox for this button needs to be extended 2 pixels to the left on 4k screens". And others will be larger scale testing reports where time is spend trying to pinpoint the exact cause of a problem. Actually on second thoughts money for bugs sounds like a great idea 😄

Or theres another guy asking about tank tracks below. Tank tracks = garage door slats

Search for a train carriage rig, its exactly the same thing but sideways. eg https://www.youtube.com/watch?v=gCj8z_a3VCc

ok, good testing. So the fact it rebooted whilst in the bios really helps narrow it down. I see the the options as: cpu fault. very unlikely, but possible. Given its repasted theres really not much more to check here. You could check for bend pins in the socket but that would never have been the initial cause motherboard fault, more likely, but these tend to be limited to usb ports failing. What I would do is unplug anything you dont need, specifically usb hubs, usb hubs in monitors you forget about, extension cables. On this, It cant hurt to run a motherboard bios update. Usually involves sticking a file on a usb stick and turning the machine on. Also really silly but possible. Are the front panel header cables all properly connected? Might be worth unplugging the 2 wires for the case reset switch that nobody uses just in case the reset switch is faulty. A power fault, and by this I mean old extension cables, the c13 power cord, old house wiring, something else in the house causing surges like a microwave, vacuum, electric heat system.. or something else very high wattage turning on and off.

We can help here but you're going to need to give an awful lot more info. Given this is an 8 year old system, but first port of call would be cooling. Specifically either the buildup of dust in the metal heatsinks or most likely the drying out of thermal paste on the cpu and gpu.

If you want to do it a bit more manually, you can also change to polygon mode then double click on a part you want. C4D will then fill in anything connected to the polygon you double clicked on. You can then texture or split that part off with the split command.

It is probably easiest to explain what the artist did in the youtube video you linked. They have used a couple of different methods (probably) in their video to avoid problems. The biggest is that they are using a really large soft light source to light the scene, so instead of the shiny surface suddenly going really bright and then dark, the fades in and much much more softly. eg in your scene the lights are 300x300mm, but in their scene they would be closer to 2000mm. It is also likely they arent even using any lights and just have a soft blurry HDR image for the lighting. Also consider that their project has no floor. This means the top and bottom of the device can be lit equally. Because you have a floor and your lights are raised up, you are forcing a bright top and a dark bottom, this makes the brightness look even stronger. Finally, cheat the materials. Just because the glass front is glossy and reflective..... cheat. Turn down the reflection on your glass so the image can be seen more clearly. For the metal, lower the IOR setting on the reflection to make the bright/dark reflections less extreme. Finally, be careful with the light you have behind the phone. Reflections on surfaces become stronger when the light gently skims over the surface. when your phone is mostly sideways on frame 123, this makes the light behind the phone blindingly bright, like the sun hitting a wet road early in the morning when you are trying to drive.

Make a new scene and pick file > merge. This will load the content of your broken scene into a fresh new c4d file. Youll need to re-set some things up again but it might get you out of a hole.
