Hi I'm a newbie and I was trying to create some clothes.

I couldn't find the play button so I just pressed the Space and it kind of works but for some reason it seems like the clothes simulator is not working properly, whenever I use the clothes simulator the fps is like 7~9 frames. I was guessing maybe it's because of my character so I used the decimate geometry thing to reduce the file size but there's no big difference. But for sure once I imported the character to Blender, everything started to slow down and started lagging a lot. I don't know why this is happening.

  • $\begingroup$ Your simulation is running and maybe due to high geometry or simulation complexity it's slow. it should run faster after it completes all the frames for first time $\endgroup$

  • $\begingroup$ also you can drag from the bottom left corner to add a window and switch it to sequencer. if your too lazy for that then hit + above and go to general>layout to add a new layout similar to the default one. :D $\endgroup$

  • $\begingroup$ @Nand27 Hi !! thank you so much for the advice 😭 I have a question tho... Do you know any other ways to reduce the character's high geometry ?? Oh and thanks to your help, I added a new layout and changed it to sequence but for some reason I still can't see the play button 😢 do you perhaps know what maybe the problem? once again thank you for your time and advice :) $\endgroup$

  • $\begingroup$ I think it would be best to share a blend file, if the below answer didn't help. You can share your blend file from here blend-exchange.com $\endgroup$

You will want two meshes, one for display(high poly), and one for the cloth simulation(low poly), so it is quicker and still looks good.

One object only

First add a decimate modifier(in the modifiers tab, a blue wrench), to your object and change the ratio to something small(probably 0.1-0.3), and then a subdivision modifier, to make it high poly again. There should already be a "collision" modifier. Put this between the decimate modifier and the subdivision modifier, so the low poly version of the mesh is used in the simulation, speeding it up.

Two objects

If the previous solution makes your mesh look bad, then you will want two seperate objects, so you don't lose the orginal topology. First duplicate the mesh(alt-d), and parent it to the original mesh(select both objects, make sure the original is active(lighter orange, not red outline), and right click, make parent>object). remove the collision modifier from the original mesh, and add a decimate modifier before the collision modifier in the new mesh like above. This way the original mesh looks the same, but the simulation is using a low poly version.

Make Cloth look better

To make the cloth look better, you will want to right click it and select "shade smooth"(so its not so bumpy). Now it will look a lot more realistic and less like low poly tin foil. You may also want to add a sudvision modifier(after the cloth modifier) to that as well, although this slows down the simulation in replay in my experiance.
