Friend posted:Anyone ever do any photogrammetry? I kinda got into it when I got my new Samsung phone, it has a TOF sensor that does some basic 3D scanning. That led me to downloading Meshroom and having fun with that. Most of it turns out garbage, but it's still pretty neat. I wonder if you could use that software on footage from films and TV to build 3d models of locations they were filmed at? You'd need lots of shots, or the camera to be moving around a decent amount, but would be insanely cool if it was possible.

man thats beautiful ive not touched 3d modelling since I was a teenager screwing around with Infini-D, but this thread is so insanely inspiring. So I've downloaded Blender and I'm trying to model a nut...  I tried doing it as a cylinder sculpted into the right sort of dome-y shape, and then tried to use the Boolean modifier with a hexagonal cylinder to cut the edges off. The shape is about right, but you can see all sorts of grot and weirdness around the edges. Is there a better way to create this sort of thing?

Holy crap, thanks, the auto-smooth normals fixed it perfectly!

Doc Block posted:when you cut into a smooth, rounded surface like that, you wind up with small, weirdly shaped faces. glad that auto-smooth normals helped (you should always turn it on for hard surface models) but a lot of the time it isn't enough, like Bluemillion said, so you wind up having to go in and manually add/move/dissolve vertices and edges. especially if you add a bevel. Another question - if I scale say a cube out to a long thin rectangle, and then do e.g a bevel, it does it proportionally so the bevelling looks stretched too. Is there a way to get the bevel to be kinda uniform across the object? I thought fixing the x/y/z scale to be 1/1/1 would fix it but it doesn't  also wow shaders are fun, I just made the most luxurious cloth to balance my tutorial donut on

No reason why Cycles wouldn't fly on ARM Macs if it got ported to Metal and if GPU performance in AS iMacs/Mac Pros is as much of a leap forward as the M1 was in CPU speed. That's a bunch of ifs though and PC's would probably still be cheaper.

Sagebrush posted:no, it's got a bunch of faces on it. this is the rhino autogen quad mesh. is this mesh maybe not suitable for auto-beveling? I made another chair, the camera angle makes the proportions look a bit funny, but it really is that ugly in real life.  I want to do this one next, but I've got no idea how to do the pinchy back bit

is there a way in Blender to use modifiers on groups of objects? I'm trying to create a symmetrical collection of parent-child objects - the 'mirror' modifier almost does it but it only applies the duplication and transform to the parent, not it's children (it also doesn't do rotational symmetry either, which is what I really need)...is there another way to do this?

bagh, that works perfectly for a regular array, but doesn't seem to work for Mirror - it dupes the whole collection into the right place but they don't get flipped/rotated, even if I set Mirror to flip. Maybe I need to do something with how I parent stuff?

that looks rad and you did a good job on the character animations, but the lack of easing on the camera moves is a bit jarring, and it seems like everything happens a bit too quickly to get an idea of whats going on...mebe have a couple different shots of the car accelerating to give more context or have part of the jump in slo-mo or something?

thats fkin beautiful how does ray/path tracing simulate subsurface scattering (or any volume scattering really) ? Is there some sort of pre-processing you can do on a volume and do some sort of analytical thing? Or do you basically just have to sample a whole load of randomly bouncing around rays?

distortion park posted:Not an interesting composition or good execution but it's neat that doing the "physical" thing of putting a distorted mesh inside the glass sphere just works and gives a serviceable (if render time expensive) result Has anyone had any joy modelling the swirly textures inside bowling balls?  I tried for ages during Nodevember and basically had no luck, using a swirly-noise distorted sphere with a metallic & pearlescent texture, inside a plastic sphere, but it wasn't quite right. It's almost like you want a principled volume but rather than diffusing or scattering it's sort of metallic

you've got way less of those 'only possible with CGI' swooping camera movements in that vid, and it looks soooo much better for it! Your modelling and animation has been solid for ages, but your 'direction' I guess you could call it, camera work and editing and whatnot, has really come on loads the last few vids.

that's cool as hell. how does the rewriting get done? Do you have a script that runs for a given seed and number of iterations and then spits out all the symbols? apologies if you explained and I just didn't get it L-Systems are loads of fun
