A fairly surefire way is to take it into Houdini, convert it to vdb's, vdbmerge and then convert it back to polys. The downside is that, depending on detail, you may end up with a very heavy piece.

You can also try Blender's boolean tools to see if they work better, I think there are a few 3rd party plugins for Blender that add boolean functions. There are several other 3rd party plugins that are hard surface modeling focused with tools that let you cut and carve shapes from each other, or otherwise support boolean operations, like meshmachine, hardops, boxcutter, machinetools, that you could check out. I haven't used all of those but since it looks like you're making non-organic shapes, they might interest you. Houdini's boolean operator got a boost a while back, you could try theirs out as well. You can also convert your pieces to a single vdb volume and then remesh it, but depending on how accurate you need the geo to be, that might not be a good route. Although you can always do a retopology pass afterwards. I'll often do booleans in steps, as opposed to combining all my parts at once, it's slower but if there's one operation that kills the whole thing I can at least get most of the shape formed and then focus on the one problematic union.

Houdini booleans are still a bit hit and miss, although with an object like that, it shouldn't be too hard. Worst case, place a cylinder as a mating object and that might give you a cleaner union.

Blenders booleans used to suck rear end, but they've gotten a lot of attention in recent years and are much better. I don't use them enough to be able to confidently say it'll work great for your use case, but it's definitely worth a look. There are 3rd party plugins made for various hard surface modeling stuff that are probably worth a look, but the raw boolean functions are all built in.

It's got full vdb tools. And then max now has a remesher that many people argue is better than the one in zbrush. https://youtu.be/ktrIhk9NFT8 Both of those plus the new smart extrude tools have turned modeling in max into something really quite spectacular. It was already my favourite modeling tool but now it's just unbelievably flexible. And from what I hear, 2023 hasn't taken it's foot off the gas... I would also reccomend trying the regular tyflow boolean tools too - they produce a much better result than either of the built in max options. cubicle gangster fucked around with this message at 04:09 on Sep 12, 2021 |

Alan Smithee posted:render out some animated sequences Yeah, go hog wild. The 1070 will be able to handle things pretty well still, and it can run lumen as well if you want to lean on that. Just grab unreal and play around a bit. When you're just using it for rendering and animations it's pretty easy to see where the performance goes so you can adjust accordingly.

Strange question, but I'm looking to have a 3d model of this pyramid made. All the sides are identical, so what would be the easiest way to replicate this without 300 days of zbrush detail work? I'm looking for it to be as close as possible, so I thought maybe just import a crop of the file to a slicer to make a litho, and then meshmixer that together into the shape, but lithographs made like that are inherently "bumpy" and not as detailed. I'm thinking of hiring someone to do it, cause this is a bit beyond a beginner "gently caress it, let's give it a whirl" level, but I thought I'd check with people who know what they are doing and see what sort of workflow they'd use to do it the fastest and easiest way. Worst case I have instructions to give the artist I hire, so having the knowledge isn't a bad thing. I'm just kinda lost on the complex issues. Any help/advice is appreciated!

Felt like making something this weekend, but didn't want it to drag out. I recalled admiring the embers rising from fires in ghost of tsushima and that sparked the idea for a little sim & vibe excersize. Models from megascans. Phoenix for the fire, tyflow for the ash & embers. the ash does get caught up in the rising smoke but it's really hard to tell. there's also probably too much of it, and too small. oh well. https://www.instagram.com/p/CTwzewbrT5c/  I posted a long time ago about doing a tutorial - it's done! 90 minutes long across 18 chapters, focusing on working with filmed footage and retouching it like it's a still, but also covering techniques to work with 'final' rendered shots and retouch them to remove objects or add details. I fear finding an audience is going to be tough - it's very much aimed at people who don't know that this is possible, rather than someone trying to find a how to on something they know they want to do. Should be going live this week, hopefully within a couple of days.

I made an Eastern Quoll with Max, Ornatrix for hair, rendered in Redshift using the new principledHair shader which is pretty cool although I started with the old hair shader and kind of transferred my maps over halfway, resulting in some blown out areas that I can't be bothered fixing. We're still in lockdown here so projects like this are keeping me from going crazy   Some other technical images of this guy on my artstation https://www.artstation.com/eoincannon

If I have a 3d scan of a figure (like a sixth scale hulk) and I find a statue stl that looks badass, is it possible to alter the statue stl to make custom bits for the figure? I have a feeling the answer is yes, but I dunno if that's followed by "and it will be crazy expensive/hard to do" or not. I wanted to make a giant doomsday figure, and I found an awesome looking statue sculpt, but the whole "rework it to fit the body" part of the plan seems like the "yadda yadda yadda" part in a plan where no one goes into detail about how batshit it is.

Without seeing the models you're talking about, it sounds like you could probably isolate the parts of the mesh you want to copy across with boolean operations, position them how you want so the meshes are overlapping, then use something like Blender's voxel remesh, or Houdini's 'polygons > vdb > polygons' workflow to make it a single watertight mesh for printing.

It's not particularly hard to do that in the 3D app, the trickier thing is making sure that the 3D printed pieces will physically work they way you want them. I've built models out of multiple pieces that are supposed to fit together, only to find that the printed pieces were off by some small amount and I had to sand them down to get them to fit, or if it was a complex piece that there was some small bit that prevented the whole piece from moving into place correctly. I'm sure there's a name for it in product design, I know that in chemistry it's called steric hindrance. 500 already described the basic process but I would mention Zbrush would also be a great option.

Can any ZBrush wizard give me a quick bit of advice?  What's the best way to sharpen up the edges on this model like what's above the quilted texture area? I've been trying the hPolish brushes and similar but they seem to deform in unexpected ways at times.

It looks like your topology is fighting against you. Have you been using Dynamesh a lot? The only way to clean that up is either go several layers higher in resolution or you could retopologize (either by hand or by wrestling with zRemesher) and then reproject your sculpted detail.

Could also use Sculptris mode with a low brush size to increase poly density just at that area, instead of doing an overall subdivide, if you just want to get the hard edges dones and fix with a retopo later. Also, you could model a separate subtool that conforms to the sheets of material with good had edges and then boolean them in. Still would have to fix the topology in a separate step.

I'm using Blender to model a large snowflake. I started with an SVG, imported that into Blender, added a solidify modifier to give it thickness, and then converted that to a mesh. Predictably, the mesh isn't always of the best quality: The plan here is for this to be really gigantic in-game, and I seem to recall that really long/skinny faces can cause rendering issues. Is there a straightforward way to clean this up? Optimizing for triangles/quads with large angles, that kind of thing? EDIT: nevermind, figured out a workable solution using the "Remesh" modifier, followed by decimating.

Yeah, remeshing is the proper solution there. That came out pretty well, considering. I've had very mixed results with Blender's auto-remesher. Rhino has an incredibly good QuadRemesh tool just for cleaning up 3D scans, and it's insane that Blender, being a dedicated polygon modeler, doesn't have something equivalent.

Now for a followup question: is there an easy way to make a bunch of convex hulls that will precisely match the surfaces here? I can easily convert convex hulls into colliders in Unity, which is kind of important to keep the player from just phasing through the walls  But as far as I can tell, Blender's convex hull stuff is about roughly approximating a shape with a single hull, not precisely matching a shape with multiple hulls.

Cut into multiple objects is the easiest way. Filling it primitive spheres is often even faster at detecting collisions.

ImplicitAssembler posted:Cut into multiple objects is the easiest way. Filling it primitive spheres is often even faster at detecting collisions. That's gonna be a lot of manual cutting.   Minimum of two hulls per section of wall. Even if I simplify the outside colliders (on the theory that the player is unlikely to spend a bunch of time ramming into the outside of the base), and take advantage of the radial+mirror symmetry to only do half of one lobe, that's still a ton of manual work that I'm hoping to avoid. As for primitive spheres...I have trouble believing that that would look good. You'd be able to poke into parts of the walls but not others, and the collision normals would be wrong, so the rigidbody's collision response would look weird. Here's an extremely early mock-up of what this could look like in-game, to give you some sense of scale: https://i.imgur.com/tDncDOz.mp4

You only need to do it on 1/6 of it and then duplicate 5 times. It's not a lot of work.

I did find this addon for blender 2.8, might have to downgrade since it's a bit old and may not be updated for 3.0, but give it a shot and see if it might do what you want: https://github.com/andyp123/blender_vhacd Or this one for 2.7, which is the same as above but has more instructions and pictures and may be more advanced: https://github.com/kmammou/v-hacd I did also find a few solutions to generate convex colliders in unity, though they're a bit old and one of them is paid, so pick your poison I guess: This is the free one, though it may not quite generate the precise results you're looking for: https://github.com/sanukin39/UniColliderInterpolator And this is the paid one ($45, oof) https://assetstore.unity.com/packages/tools/physics/concave-collider-4596

Definitely easier to just do that by hand. Just duplicate chunks of the geometry in the shapes you want, hardly even any manual work, unless you are planning to do this for a lot of other objects.

Is there anyone who could guide me into the first steps of making a simple addon for blender? In this particular one, I just want to add an auto-off for a tickbox in blender. One of the most useful tools in blender is being able to move your viewport as the camera to change camera angles. for some reason you can't undo this, and so if you have a viewport lined up and you move to look around it, if you've left that tickbox on, you move your view port and you can't undo back to the previous one. and this fucks me right off. and I've done it loads of times. my own drat fault of course but still... it seems like making an addon or script could handle that easily
