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.

Take the power usage with a grain of salt. Yes macs are efficient, but the quoted gpu numbers are always way over the top compared to what they actually draw. when the 4090 came out, people were running around claiming it would draw 600w. The real world top end is 300w and with a slight undervolt you can bring it down to 200w for only a few percent performance lost. Real world 5090 at stock numbers will be 400, 450 watts at most. Youll be able to bring this down to the 300's with an undervolt.

The problem is they're nice and quick for working, but ultimately lack any real grunt to get the rendering done. The M4 GPU is equivalent to average modern onboard graphics chipset, or an old budget Geforce 2050 card. The M4 Pro is similar to an old 2080 gpu or a modern budget 4050. The only chips with any real grunt are the Max and Ultra which are comparable to a 4070 or 4080 depending which you pick, but you're not getting them in a mac mini and you'll need to 3x or 7x the price to get the spec with them.

Looks fine. Im not sure i'd pick a motherboard based on usb ports though. usb hubs will give far more ports, with more power, more conveniently placed. 20 usb ports round the back under the desk is the last place I want them. For memory, try to stick with 2 sticks of ram on the amd platform. As soon as you stick 4 sticks in, they will run much slower. With 2 sticks you can do 96gb these days. Its not end of the world but it affects 'realtime' type apps more, we're talking maybe a 20% difference in playback fps. If you want quiet, go 280mm or 360mm AIO. the liquid acts as a heat storage so it can quietly dissipate the heat over time. Just make sure the bios is set to not instantly ramp up the fans under load or they will have a tendency to keep revving when they dont need to.

Except its utterly unusable because if you release the keyboard key and the mouse button in the wrong order, and you will, then you get stuck in the new mode. ie. im in rotate mode. I want to quickly move something, so I hold down the E key to temporarily enter move mode. Click and drag to start moving. When you are finished, you release the mouse and keyboard buttons. However, if the keyboard key releases a millisecond before the mouse button, you are now stuck in the new mode. Or if you have a heavy scene, you press and hold E to move something, then click and drag. If c4d hasnt updated to the new tool before you click, you will be stuck rotating the object instead of moving it.

Add another zero into the ray epsilon setting

I know the pattern doesnt stretch in real life, foil doesnt stretch. But there is literally no other solution. It doesnt matter what you do with the material projection, or UVs, you are asking for the impossible, it cannot be done. The only way it will work is if your 3d model incorporates the same folds, creases and imperfections that you see in the photos. You have to model the folding of the foil to keep your even pattern, there is physically no way to make it work on a smooth crease-less foil neck. Go take a look on turbosquid: https://www.turbosquid.com/Search/Index.cfm?keyword=champagne+bottle&media_typeid=2 Every champagne bottle on there either; Doesnt have a pattern on the neck Has the pattern squash and stretch Has the pattern cut off 4 times with cubic projection with seams Curls the whole pattern around like a beer bottle neck label Here, cubic mapping using folded flaps to hide the seams. even diamonds and cyl shape test.zip

But the pattern there gets squashed up and crumpled into all the wrinkles. Thats why the wrinkles are in the foil, because a regular diamond pattern cannot physically work on a tapered bottle neck. Same with the quilt. In the corners where the pattern cant physically work with the 3 dimensional curve, the quilt is forced to make a series of folds and creases. Without the folds, it wont work. You need to choose; You can either have clean foil, in which case the diamond pattern will squash and stretch. Or you can have an even diamond pattern, but you will need to model in all the wrinkles and deformations needed to allow for that pattern.

Youre asking for the impossible. The pattern WILL get narrower at the top and it WILL get wider at the bottom. Otherwise the lines wont meet up round the back.

Which is ironic because that same decision is what crippled lightwave's development and adoption, to the degree that they never put the modelling and animation tools into a single app.

We cant help without seeing your settings. Edit > preferences > renderer > redshift

Grab a used Aeron from a company liquidation, theres always loads of them around.

You need to keep some things in mind when working with metals. The light you shine on them wont broadly be seen from the side you shine it on. What I mean is, metals are mirrors, they bounce light. If you have a flat metal surface, dont place the light near the camera light a flashlight because it will hit the metal and bounce away into space. Instead place the lights behind the object so when they bounce off the metal, the bounced light hits the camera. Dont put the lights where the blue light is because you think it will light up the side you are looking at. All the blue light will ricochet off the metal and fly away. Place the light where the red light is so that the light bounces off the metal and reaches the camera.

Figured I haven't posted any recent work here for a while so here's a few of my better recent videos. The ones at the top are more fun as we've been given more freedom creatively to do what we think is best rather than taking orders from the suits with excel spreadsheets. All productions are 4-7 days of work. c4d 2024, octane 2023, rendering on 10x geforce 4090 cards. Not much in terms of post work, we tend to get it 95% there in-render, mostly just brightness, contrast and saturation changes. Plus a few lens flares on the top video.

The dome light projects a panoramic image down onto your scene, you MUST add an hdr image into the dome light or it will do nothing. Attached rslight.zip

This is the exact same problem as from your other thread a few weeks ago. Stop using portal lights, they are only for using outdoor sunlight passing through glass windows, don't use them for anything else. You have a giant light which is set 10 EV stops higher than default. This makes it 1000x brighter than normal. Even a dark metal will look bright grey if flooded with a 1000x strength light. You need a simple starting point. Delete your lights and the sky. Add a Redshift dome light. Then in the settings load in any hdr panorama. This will give you a decent starting point for lighting the scene.

Theres either a bug or a cap somewhere. I got 150gb into the full 3tb library but all downloads now just fail. IF anyone else manages to get the whole thing... do let me know.

Ironically I once went to advertise 3D Fluff tutorials in the magazine but had the advert rejected because the advert was deemed too likely to make the reader think there was a printing problem with the magazine. It was a completely blank white space with "3dfluff.com" in the middle in a size 11 font. That was the £900 which would have saved the magazine, you fools!

Agreed. Either keep using the older version you still have or time to pick a new render engine. Standard is being wound down and no new updates or likely plugins will be made for it now that redshift is the new default engine.

Rendering 3D room interiors where most of the light comes through a glass window is difficult for most render engines. For technical reasons I won't bore you with, they tend to make very noisy grainy images which take ages to render properly. Portal lights are a special type of light designed to solve this slow rendering problem. If you want a simple explanation; the more of the lighting which happens on the first bounce, the easier it is to render. So If a light directly hits an object, it will render cleanly and quickly. The more the light bounces and bends before it reaches its destination, the slower the rendering will be. So for sunlight coming in through a window, the light bends once when it enters the glass, again when it leaves the glass, and so its only the third bounce of light which actually reaches the room. For the light which hits the ceiling, thats another bounce as it reflects off the floor, so the ceiling in the room will be very grainy. To be honest, you probably won't need to worry about them until much later on, for now just stick with the simpler lights at the top of the light menu

Seems the new AI importer is choking on the file. Open the file in Illustrator, save it with a new name and in the save window, set the file format to illustrator 8. Now in C4D, use the main File > Open command to load the file and it will use the older code, this appears to work fine.

You have no light in your project, you have nothing but darkness. "Portal lights" are designed for creating light through glass windows, dont use them to light your scene. Either use an area light, or a point light, or spot light, or dome light. Anything except a portal light.

you have 50 objects surrounded by darkness, what are you hoping to see? "Redshift > Objects > sun and sky rig" to get started.
