You can actually stack the Subd > Shrinkwrap > Decimate unsubd > subd again modifiers to preview the final result, without making any destructive step yet, it's heavy in performance but it's worth it when you're working on complex meshes, i tend to use this when working on car surfacing as making any destructive step would require quite a lot of work to go back and fix if done wrong.

Thanks for the tip!

Sir. I can not thank you enough for anything I've learned from you and specifically this video. You're the best 👑

Damn dude the way you describe it in less time, so beginners can also understand is what impresses me the most

That's the most elegant solution I have seen for this problem so far. Very nice, sir!

Thanks, dude, for your tutorials and an amazing book for Blender community! God bless you!

Thank you!

ULTRA HANDY!! Thank you and god Bless you! I followed modeling an exercise step by step also. Thanks again!!

That's amazing tutorial. Thanks

You are the best. Thank you!

Super nice. Indeed that's a typical Blender little problem.

Thank you so muuch

Best source material for making holes

That was an intense amount of steps but effective. That’s a come back too kind of tip lol.

Bloody hell !! That's brilliant ... and a little complicated. I'm going to have to watch this a few times to make sense of it, and try it out. But the result was stunning. That silver matcap that you have is also quite beautiful. Thank you for this. PS I don't feel at all guilty about consuming this content because I bought your book!! 😜

Thank you! I'm rewriting the part in the book about "10 ways to make holes" so that it all works with Blender 4.0. And when I've remade all the methods as 1-minute videos, I will also publish a longer in-depth video that takes a bit more time for all the steps. So that's something that may be helpful if this one is too fast. Don't feel guilty :-) Thank you so much for your support. Thanks to people like you the book can continue to be updated.

@@BlenderSecrets thank *you* !! A bit of extra instruction is always very welcome for us noobs. None of this feels intuitive for us beginners, so some extra 'unpack' is always very helpful. 👍

Cool

I didn't understand why you duplicate the cylinder

how do I reduce the topology after inserting a circle like this? I created a knob for a drawer, which I had to create a bunch of loop cuts in the mesh to create a decent circle on the surface. for example at 0:50 there are a whole bunch of unnecessary loop cuts in the model. how do I get rid of that without messing up the circle?

Ugh.... I love holes

yes m8

Did u uncheck flatten when using circle?

@BlenderSecrets

8 ай бұрын

In my experience that option doesn't really do much. If you want to flatten it, you can go to LoopTools > Flatten.

I tried 2 versions, one with: SubD=1, Shrink Wrap, and SubD=3. The other with: SubD=3, Shrink Wrap, Decimate 6, SubD=3. They both look identical. I would recommend not bothering with the Decimate step as it seems unnecessary. Tell me if I am wrong.

I don't understand what you're doing when assigning the vertex group. You have the hole selected, press the plus for new, but then I get lost when you highlight the remove and assign buttons and flip the selection. It would mean the world to me if you could help me make better sense of this, as I've been trying and failing to model exactly this shape for a few months before finding your video.

Just wait a bit, I'm working on a longer video about all the ways to make holes, and it will include a longer version of this topic.

Basically the vertex group tells the modifier which part to ignore. If the hole also gets shrinkwrapped to the other object, it will no longer be a hole. So to protect its shape, you exclude it from the shrinkwrap. Hope that makes sense.

@@BlenderSecrets Awesome! Thank you so much for taking the time to make a more in-depth version. This shape has become the bane of my existence, LOL. Can't wait to check it out.

WOnder why it took some time before discovering this channel (started Blender this year in April, also mentioning I took break cuz other school projects). Quite late I started (25y) and wanted to do 3D for a while. At school we use Cinema4d and some specific classes like 3D printing use Blender. I used Blender for the first time at my internship (own school) :) Subscribed, nice quick tip!

I don't understand. What's the theory behind this exactly? How does shrink wrapping to the duplicate fix the texture distortion exactly? Everything except the hole shrink wraps, so the general shape should remain the same right?

No. When you circularize the hole, you're moving vertices around without respect to the curve and making the normals of the surrounding quads inconsistent with the curvature of the rest of the cylinder. That's why the surface appears bent and warped around the hole. The shrink wrap modifier is taking the new mesh and moving the vertices to the surface of the duplicate, making the vertices (and thus the normals) consistent with the surface topology of the cylinder again. This fixes the distortion.

@@radiocage Sorry, I didn't quite get you. What do you mean by "without respect to the curve"? Aren't the vertices moved around the curve/circle to give us the hole?

A surface normal is a line that extends perpendicularly from the plane of the surface. Light and specular reflections are calculated based off of this normal (and others, like vertex normals, etc.) The texture looks distorted because the vertices of the hole you make are not aligned to the surface of the cylinder. This makes the normal of the surface inconsistent with the rest of the surrounding geometry. When you use the shrink wrap modifier, it moves the vertices of your selected object (except the vertex groups that you specify) to the surface of the object you choose (in this case, the duplicate cylinder.) This action makes those surface normals consistent with the surrounding polygons, getting rid of the distortion you see.

@@radiocage I understand what normals are. Though I am confused by what you mean later. What exactly dk you mean by the hole vertices not being aligned to the surface of the cylinder? Do the vertices not literally make up the cylinder themselves? How can they not be aligned to it? Sorry, English is not my first language so I think I am confused by the wording Do you mean that shrink wrap "fixes" or "repairs" the vertex normals thus making them look right?

It is not working for me, I did literally everything step by step, but it just creates some annoying noise and the hole is still bumpy.

I'm lost. End up with the exact same topology by the end of it. Doesn't look smooth at all.

i never knew we could Apply Visual Geometry to Mesh... i didnt know the tool existed.. arg ! :)

That's just going to give you uneven topology

Love ur vids

Amazing! I have tried to add a heart to a door, and it was an arduous path, I found the knife and with that I moved forward And now you come and show me this with such ease and beauty, and I had to make two holes and a triangle at the point of a knife.
