I somehow edited out the last parts where I modeled the holes; sorry about that. I basically booled out the holes and cleaned up the mesh.
Lord, this is exactly the kind of tutorial I wanted to see from you. It's amazing.
Awesome!!
I also have a UA-cam channel on subdi modeling, and they also ask me the same questions as you: why don’t I do this in CAD programs, why not in Plasticity or MoI3D, etc. Well, firstly, this is my hobby and I like it, secondly, knowledge of subdivision helps to better understand the topology and mesh structure of the model, and thirdly, topology helps to use models in any conditions, be it advertising, games, various simulators and so on.
14:00 - Two additional edges on a rounded chamfer should not be at equal distances, but as close as possible to the outer edges of the chamfer, because the rounding should be interrupted precisely in these places. If you do it at equal distances, the chamfer rounding will go further than it should.
The approach you showed in the video only works on simple models. Essentially, this is reverse engineering after 3D scanning without precise reference to geometry, but this is not important, because accuracy is not important here. If the part is complex, then the order of execution will be as follows:
1. The best solution is to get rid of all the small chamfers (which only emphasize the shape of the model) in a CAD program and only then export it to a 3D mesh. Larger chamfers and roundings do not need to be removed.
2. Clearing the model of unnecessary edges (which lie on the same plane). In C4D this is easier, because isolated areas (holes, etc.) do not require mandatory connection, which is mandatory for Blender. In Blender, such cleaning is done using just one command and in the end we get a 50% ready model for further topology.
3. Reduce the density of the geometry in all places where it is required, mainly holes and rounded chamfers.
4. After all this is done, you can start creating the topology.
5. Small chamfers (roundings) on the edges of the model are made LAST!!!
Thank you very much for the insight and your time, perfect tips!
Great video and explanation on the importance of clean SubD modeling taking into account the entire production pipeline.
Thank you very much !!!
This kind of modeling is the way to go. If you just start on light/easy objects and move up to harder objects you will get the hang of it on which tool you need to use to get the best result.
Right in time when I need it for my work. Was strugling finding the best way to convert a CAD model with lots of details to a quad model to use smoothly in C4D. Thanks a lot !
Awesome!
Love watching your workflow 🙌 Clean work
Thank you!!!
Game engines render in triangular form regardless. In fact, the non-SubD version performs better in the game engine, with fewer vertices and more accurate normals. When exporting with NURBS tools, precision control is essential. If N-gon output is possible, it would facilitate UV mapping and baking processes.
And in every other case quads are better.
@@Bernwolff The only scenario where performance would be better is when the mesh needs to deform.
I was thinking the same!
I was waiting for this kind of tutorial...thanks
Great!
you are the best! please keep up the good work!
Thank you!
You're a subD champ! Thank you for all your amazing tutorials!
Thanks Eddie!
I needed this two weeks ago!!!! thanks, such a good tutorial!
Thank you!
This is much needed! Thanks so much Mert
Thank you!
Hi. always enjoy your tutorials. just have a question. that when you started learning 3d modeling have you been also learning stuff like rendering and texturing even zbrush along with 3d modeling or you just focused on 3d modeling and nothing else and training everyday.
Thank you, I learned modeling along with texturing and rendering, then started to get into animation.
thanks for all your hard work poly!
Thank you!!
This is fantastic. I appreciate you taking the time to go over this. It's very helpful.
Thank you!
Please consider modelling "Nintendo 64 controller" for you next course, It's really challenging and there is no actual tutorial for that, I would for sure buy it....! Thank you!! for all the great tutorials so far.
Thanks for the suggestion!
3:04 I actually prefer to have a higher poly CAD, because I can rely on shrink wrap when doing the retopo
5:07 oh nice, I never used this reproject result option.. I always enable snap with polygon mode... going to try next time :)
20:10 always remember to save a copy of the geometry with the deformers before baking it, in case you need to adjust something later !
For projection, purposes, high poly mesh will work better indeed.
Thanks for the hints!
So you basically remodel it? I kinda was hopng that there is a magic button to help dealing with stuff like this, but nope. It's still just a brute force :D
Yeah :)
can you model a military pouch , I struggle with it.
maybe, maybe not :\
Your tutorials always make me learn more. Now, I'm confused. My job is boring, it only requires simple modeling and rendering, it is easy but does not make me happy and progress, the salary is mediocre, I do not know if I should continue.
Yeah of course you should keep learning; more skills = more income and more opportunities.
@@polygonpen You're right. I need to keep strengthening myself and making myself better.🤗
Nice
thank you for your videos
So basically to get CAD models Sub-D ready, you're basically just modeling it again with quads so having to model twice :p
Can't you use a method of modeling that automatically follows the original models shape when you are extruding etc? Like a wrap?
Unfortunately I don't know any automated workfow like suggested, bevels make it nearly imposible to get good resuts so you end up retoping the whole mesh.
@@polygonpen one thing in the future A,I may be really good for. UV unwrap too
@@iKaGe01 Yes, this is the one thing AI may do to kick people off their jobs if it figures out topology.
@@polygonpen When I said about the automatically following the models shape, I was thinking about a shrink map modifier.
BUT I was also looking into 3D Coat today. That allows you to retopologize too and seems to be rather quick using draw lines to create quads. May be worth looking into and it is also perpetual and not all that expensive considering

А какой смысл делать сначала в CAD, а потом переделывать в C4D?
согласен. думал, что это будет какой то крутой тутор по инструменту или плагину, который поможет ускорить работу, а чел тупо 30 минут ретопит руками)
I know right? This is pointless.
CAD is much, much faster. No matter if you make design from scratch or use some slopy 2D sketch. Imagine that you make such ( or more complex ) model then boss say " Nice, but can you change this and this and this and...". In CAD you can make such changes with less pain. Also, sometimes you get CAD model, and your task is to make proper subd model.
In any case knowing how to make retopo of CAD model is very useful skill.
А где было о том, что это делается в начале в КАД? Чел просто взял модель из КАДа и заретопил её в сетку с топологией. Подозреваю, что ваш вопрос о том, а зачем это вообще нужно. Разные цели: если нужен просто рендер, то это можно и в самих КАД-ах сделать; если реклама, то в других программах, к примеру в Синеме; если деталь будет анимироваться и к ней будут применяться деформации, то без ретопа тут никуда. Есть четвёртый случай, когда это делается ради практики в топологии.
I find it very difficult to see how to clean up the grid. There are basically rules that you should follow in order to tidy up the grid. Maybe you can do your own exercise for this?
Unfortunately, I deleted that part while editing, but I will do a separate video about semi circle holes and details.
@@polygonpen Yes please, and thank you!
Sir, Please we need Produce animation and simulation tutorial
ты лучший!
спасибо
Wolverine, x-23 claws, katana modelling video? I like superheroes, that's why I want them, but yinede bence güzel olur...🙃 I like your videos.
Thank you but making these tutorials çok uzun sürer, teoriye odaklı kısa tutoriallar çekmeye çalışıyorum daha çok.
@@polygonpen Eline emeğine sağlık, You are our C4D hero
@@vrram-gm1xb Thank you!!
I am curious why you chose cinema 4d over other modeling software avaliable?
I also spent a lot of time modeling in C4D (several years), but about a year ago I switched completely to Blender, because the modeling in it is much better than in C4D. Real-time modeling and rendering was important for me, and drawing from a 3D model is much better done in Blender (something like BodyPaint in C4D). Everything else was done simply terribly (I won’t talk about that now).
@@mrdixioner can't say I agree, I actually switched from blender to other modeling software and there isn't a single thing about blender that I miss, I found it lacking compared to what other software offers, even after purchasing multiple add ons.
I didn't choose Cinema 4D on purpose; it was just the software I began with.
In my view, the specific application isn't very crucial for modeling; what's more important is having a solid understanding of topology.
While Cinema 4D may be missing some significant tools, there are workarounds, just as Blender lacks certain basic tools, such as the clone edge feature (equivalent to the Slide tool in C4D, which I use a lot). Nonetheless, I continue to enjoy modeling in Cinema 4D because of its simplicity and cleanliness. It's also an excellent application for beginners, thanks to its straightforward and uncluttered user interface, with most necessary tools available in the right-click menu.
@@polygonpen I think Cinema 4D is the best program in its class!!! It is very simple, it is very easy to learn, all the necessary tools are in place and there is a huge number of them (you also need to take into account the system of tags, fields, and of course the famous Mograph). Cinema has the fastest system of particles, physics and all interactions in general! Built-in tools for a shadow catcher, a projection camera, an excellent material editor (without idiotic blender nodes), an excellent UV editor and many other excellent things that we can talk about endlessly! My move to Blender is purely related to modeling and rendering, and this is just my opinion, but I will always consider Cinema 4D to be the best program!!!
so easy
I learn a lot from you
I apply all your lessons and I can make simple models
But when I start a complicated task, I cannot... and I do not know where to start
Is 3D modeling very difficult or does it require a lot of practice?
Can you create lessons for us so we can learn where to start in designing the model? please 🥰
It is all about practice, trust me, I want to do a tutorial that covers everthing for beginners, hopefully this video will be on the channel soon!
@@polygonpen Thank you, you are the best 3D modeler, and I hope to be like you one day 💖🙏
