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.

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.
