Bro Please make same video on other simulation..🙂 and thanks for such great information.

Thank you for your appreciation!

rehearsing and video compositing are the keys to a perfect tutorial. Sadly 99% of youtubers don't give a f... about that and internet is spoiled with useless content. Or even worse : with ultra useful content but then one has to watch 30 minutes of boring video to extract the 15 seconds of what's actually useful in it. Good job Artem did there for sure. Much useful.

Well, it's all mainly based on the documentation, but combined with a practical demonstration, some of my own findings and conclusions)

KZfaq HAS such a tutorial... you're on the very webpage of it O.o... When you eat a good hamburger in a Burger King, do you also say "Burger King doesn't have such hamburgers ? "

Thumbs down are often from people who don't know how to use a search engine, end up in the wrong place, and express their dumb frustration before moving back to whatever they were looking for.

Thank you, I'm happy it's been helpful for you!

​@@artemtovbaz8452 Hey man, thanks a lot again. I was going through my work and just remembered about this video. I'd love to share what I did with this explanation video :) www.behance.net/gallery/105160435/The-Luxurious-Reincarnation-Short-Film

Hi! This issue might happen by various reasons. They could be: flipped faces, small scale, not enough geometry, not enough friction, collision distance is too high, too complex simulation, ect.

Hi! Thanks for the question :) It might be that your objects are too small or you should check the collision settings for both meshes. Your cloth also might be bouncing because it stacks in the collision mesh. Hope it helps ;)

@@artemtovbaz8452 I re-watched this video and scaled my model and cloth way up and it helped...somewhat. motion is still primarily up however- IF cloth is draping over figure. IF not it crinkles up but drops down??? So it must be something to do with the figure. What does it mean to "stack in the collision mess"?

@@paxnfacto Sorry for my English ;) I mean it gets stuck in the collision mesh. It usually happens when the simulation isn't precise enough. Try adding quality steps and decreasing Collision value. However, I guess, there is something about the geometry of your meshes. Check face normals orientation, as well. Try with a flat cloth to test your settings.

Vertex Mass stands for the vertex mass of each vertex. If you have 100 vertexes, for example, the total mass will be calculated like this: Vertex Mass * 100. Basically, the heavier is your mesh, the more it suppresses other parameters. Try testing lighter and heavier objects more. You should take other physical parameters into account, as well, like the relative scale, for instance.

@@artemtovbaz8452 thx for the answer. Well I just wanted to simulate couple of 🍁 faling down with some forces (wind and turbulance) but even with super hight force valuea and 100s tries it doesn’t work as expected

@@Wzxxx You could try increasing Air Viscosity and keeping Vertex mass low, as well ;)

@@artemtovbaz8452 thank You for the content and support. I will try this for suee

@@Wzxxx Hope you find the best solution, anyway)

Hi! Sometimes it makes sense to go around using cloth simulation only, especially if you just need a static image. I would simplify the process as much as possible, if using cloth simulation was too elaborated decision for this task. I would make the folds like shown in many other curtain tutorials, then simply booled the holes and added the rings. I believe the process should be more abstract as it is done in a virtual environment, so keep it simple, model when necessary, combine methods. Sometimes I pre-model the shape of my cloth piece and then go for cloth simulation. It is also a good idea to use cloth simulation after cloth simulation in some cases, as well.

​@@artemtovbaz8452 The steps I ended up with that I think I'll stick with is: 1. Model the hole and surrounding cloth, but do it at much higher scale to avoid collision issues with the pole. This "have to scale" thing is one of my pet hates with Blender. 2. Extrude the top once and the bottom as many times as needed to get the length. 3. Assign material to fabric and ring, and UV the ring as a strip of quads filling the full UV space. Fake bulge be U or V axis. 4. Assign ring verts to a pin group, possibly include the fabric above it as well for the simplest method to avoid it folding over itself. 5. Extrude the fabric sideways, clone and rotate as needed to get a full section with 60 deg rotated holes, then array the whole thing. Copy the object at this point for configurational changes. 6. Apply the array and merge, then delete the parts outside the holes. 7. Select by material the fabric (only). Then UV the fabric and fill the entire UV space. This allows use of simple UV math to fake fold borders in the material (if U0.98 then fold material etc). 8. Select pin verts and hide the rest. Ctrl+h to create hook, R to repeat for each ring section. 9. Create loc+rot keyframe for all the hooks. Repeat for extended and contracted parts. 10. Add the hanging pole as a separate collision object in the middle of the now angled holes, no friction. This is not for the rings, but for the cloth to not fold across the pole. Add wall and floor collision objects as needed. 11. Add cloth modifier and run the simulation. Might want to add a little bit of randomness to the fabric first. 12. As for shading of a see-through curtain, I go with around 80/20 Diffuse/Translucency with hole mask Transparency (with view angle considerations to account for no thickness) for the main fabric and only Diffuse for the borders. I stay away from Principled as it doesn't have any diffuse transmission properties. 13. If needed, some preferred method for sculping in additional folds and details.

@@gottagowork Thanks for sharing your method! You could make a video tutorial out of it ;) I hope it come in handy for other artists.

​@@artemtovbaz8452 Yeah, that's now my modified approach; plane circle for the "flat ring", extruded into surrounding geometry. Apply an array and animate hooks to control the rings which are also the pins. Goes from flat to folded, then back to extended but now with varying angles and positions. Bake the cloth, grab a few interesting frames as shape keys and get rid of the cloth modifier. Touch up as needed, particularly you want to be able to see through the rings. Any of these shape keys will now be the basis for more intricate cloth simulations involving collisions, wind etc, where the top part is weight painted pin. If you need solid rings, you can copy the faces out by material and extrude them in both directions. I'm curious, does anyone else use a hint of Translucency shader mixed in, on curtains? Here is a see-through curtain that also provides shadows on the backside - which means it would also bleed colors into the room: c0.wallpaperflare.com/preview/186/922/321/united-states-chantilly-window-shadow.jpg Subsurface scattering (Principled) with solidify does not light up the room, only the curtain.
