I think generally having these n-gons on purpose works only for these concept art renders. A better workflow in my opinion is to use a 16-segment cylinder for both, fix the geometry to quads (takes about 5 mins) and then use a subdiv modifier to get detail as you need. I think in the long run the n-gon method will cause more and more frustration because you'll constantly have to fix the geometry to work or come up with these work-arounds like the bevel shader. When you do clean topology on your model once you'll never have to do it again. Everything will also get easier: UVs. rigging etc. And if you don't learn to do clean topo, you'll never get a job as a 3d modeler (I mean asset or character modeler, maybe as a concept artist). This doesn't mean that you can't use n-gons for flat surfaces though as you said, you definetely can and i think thats a good option to save on vertex count in general. Cheers.

WHERE WERE YOU TWO DAYS AGO WHEN I NEEDED THIS 😭

3:20 It's not the "bend" issue at all, because the poly on your cylinder are perfectly *flat* . You may check this on top view. It's normal smoothing/triangulation issue. Smoothing with neighboor polies causes artifacts.

So, we meet again, boolean on curved surfaces! My old nemesis!

Josh went from teaching how to get perfect geo to teach why you don't need it. I managed to establish blender as our go to solution in my department. We need to go back and forth between autodesk and blender and good topo is essential in that context. I still learned everything from Josh, starting with how amazing bevel-weight is to model an iphone charger. Thank you Sir!

This is the Way. as always, Josh & Ryuu.....keep hammering!

very useful tutorial

Non-Manifold Geometry: Booleans can sometimes create non-manifold geometry, which means the geometry has irregularities that don't adhere to the standard rules of clean 3D modeling. Non-manifold geometry can lead to shading artifacts and unpredictable results when rendering, as the software struggles to calculate proper normals and shading across these irregular surfaces.

Clean Topology: Booleans can produce messy or unclean topology, with intersecting edges, duplicate vertices, and other issues. Clean topology is essential for proper shading and rendering. When booleans create messy geometry, shading artifacts can occur, especially when the software calculates normals and shading across these irregular surfaces.

Intersecting Geometry: Booleans can introduce intersecting geometry, where parts of the mesh overlap or intersect in undesirable ways. These overlaps can confuse the renderer when calculating shading, leading to shading artifacts.

THANK YOU

Ngons and Triangles: Booleans often create ngons (polygons with more than four sides) or triangles in the resulting geometry. Ngons and triangles can lead to shading issues, as they might not interpolate normals properly across their surfaces, causing uneven shading or artifacts.

Great video Josh, very informative and a useful backup to keep in mind. Cheers.

Subdivision Surfaces: If you're using subdivision surface modifiers in your modeling workflow, booleans can lead to pinching or uneven smoothing when applied to a surface with varying densities of vertices. This can result in shading problems along the edges of the boolean operation.

Thanks for the video. If you are doing a Boolean on a curved surface but you want to then create a plane from the resulting surface where the Boolean intersects, what’s the best way to do this. The issue is you get overlapping geometry where the vertices intersect, so how you’d then create an even mesh is difficult. I hate using the subdivision modifiers because they are approximate and I do models from measuring real shapes and it shouldn’t be the case you have to worry about order. Any suggestions? This is neat with the tool that gives a boundary so you can bevel because again you can bevel, add the Boolean and not have to worry about order of all the geometry, especially useful if you are modelling measuring dimensions of your object to actual sizes.

Thanks SIR! The JUMPSTART COURSE is extremely beneficial for beginner..everything is well explained with practical knowledge...

Thanks Josh, very clearly explained!

Your hard-surface tutorials taught me almost everything I know about Blender today. Thanks a ton for all the hard work you put into these! As goes for the shading issues; what actually causes them? I get the concept of isolating it, but from a shader perspective I still don't really understand why they occur. You could export them to a game engine and have them render just fine with a standard lit shader, so why do these issues exist in Blender?

Hello sir, You got an awesome video...before watching your beginners video I almost gave up blender and back to blender because of your video... But I have one kind request... I have so many great videos you have ... But the problem is it's hard to start for beginners cause all videos are mixed up and not in any order for new uses like me ... Please add all begging guides to one playlist will be greatly helpful... It's a kind request 😁🙂😁🙂😁😁😢😢😢😢😢😢😢

This video is giving me an anurism. Quads don't matter? Ive always seen since the beginnig days of my 3d modelling journey that Ngons is cheating. Like a the roof of a house lacking any structural support. Fixing shading issues by increasing geometry by adding ring loops like that is blasphemy. Surely you're being satirical? 😂 You're right shading issues come from bent faces and a bit of clever retopology isolated to that specific area can help while maintaining proper edge flow so the model is tidy and geomtry is clean and allows for smoother bevels or proper distribution of chamfers. I just can't accept that Ngons are ok. I couldn't sleep at night. I think the only way you get smooth bevels on ngon edges is by using special addons for blender.

Not the point of the tutorial but remember to try and line and up whatever youre intersecting best you can before applying bool. Just to save some work for yourself. Mesh Machin3 and Quad Remesher have also saved me countless hours of cross eyed click click click time time time tick tick ticks

Hey Josh, I’ve been an aspiring 3d Modeler for games, creating both hard surface and organic surface models for games. I’ve been following your channel for awhile because of your great tips and knowledge, but one particular question I always can’t seem to find online is how to do these kind of tricks when you need to convert your end result to low poly? Almost every approach online I have seen recommends that you use higher resolution, which does work and gets the job done for the high res model, but when baking the high poly cylinder to the low, i always get large artifacts or distortions around the bend where it enters the hole cut into the cyllinder, and i’m never quite sure how to perfect that kind of low topology to fit higher resolution cuts into the mesh. I would really love to see any advice or a tutorial on this kind of subject, as it’s one i’ve been struggling with for over 8 months now

Always a joy to see a new upload. thanks.

Consider Boolean Order: The order in which you apply boolean operations can affect the results. Experiment with different orders to see which one produces cleaner geometry and better shading.

The mesh machine workflow is fine for allowing you to safely add a bevel modifier, but it returns with the same shading issues as before. Not a perfect solution sadly

I kinda miss those modeling video series like the robot ball.

cheers bro

Alternatively, you could learn to model properly, which doesn’t take much time and gets you a job.

5:10 - You can see, the shading issues are already a lot better Narrator - *They weren't.*

This has nothing to do with non-planar faces. In Maya, you can easily select non-planar faces (I believe you'd need a script for this in Blender,) to verify that indeed the boolean is *not* creating non-planar faces. The issue is that booleans struggle to calculate ideal vertex normals on curved surfaces. The lower the resolution, the more pronounced the imperfection due to it appearing on a larger surface area. Cranking up the resolution doesn't eliminate the imperfections, you're simply making them smaller. You're charging $1k for hard surface modeling courses when you don't even know something as fundamental as this? 🤨

so your solution is to make it higher poly, not making the topology make sense, i dont get it... not good guide for videogame assets

Again and again... the same methods from video to video.

👍👍👍

Hey please make videos on retopology
