Its a bit annoying to have to calculate and render a bunch of triangles in lua, itd be nicer if roblox meshes supported deformation or at the very least soft body. |
|
|
my destructible car and prop tests are pretty laggy when you hit things, i built them with a bunch of triangles and deformed it at certain points
but i have to constantly update each triangle on collisions |

bump, i dont think anybody knows what this is so i will show you
mesh deformation used in character animation:

soft body physics:

Uses:
dents, bendable objects, any type of animation (character, vehicular), fluid-like / cloth-like / squishy physics simulation
Can be mesh deformation of a certain point or selections/areas of points |

Do you think mesh rigging would solve this even for cars if they made something like rigging?

yes but then you still would have to do soft body physics by yourself
1 big issue: weight painting
every joint in the rig has to have weight painting (weight affects how strong the pull of joint movement is in certain locations)

So it would be in general easier for roblox just to implement simple mesh deformation instead. |
|
|
i.e. if you made a car and rigged its wheels, each wheel joint would be heavily weighted around the wheels and no weight on the car itself or the cars mesh will also be pulled along with the wheels mesh |

imagine if roblox added fluid simulation too lol |

Roblox in a long time has not been very advanced when it comes to these things. I would be surprised if they added something like this. What you're saying is something like a realistic simulation of a car crash and that is something that Roblox is going to take probably years to make. I've seen some other cars on Roblox that have crashed and they only unanchor when they collide but not bend. Maybe what you're saying is something that's similar to bendable meshes like you see in Roblox ads where a Roblox character has bendable arms or legs that were done in Cinema 4D or Blender. Bendable meshes were first mentioned on the DevForums before but they are still kind of stumped on making that a feature. It takes a bunch of advanced lua coding to make something like that since Roblox is mostly made of blocks and spheres. It'll be quite a change when Roblox makes something like bendable meshes

It most definitely will not be done in lua or lua only though, most likely on the engine itself instead as it will have to have custom physics and the textures/model will have to stretch/bend |
|
|
but other than that as long as roblox is rendering polygons correctly then you could deform the mesh by moving the vertices of any given mesh and moving a selection of vertices at the same time by using calculations relative to the part or maybe just world to position the new vertices |

cmon admins read pls :( i dont like dev forum |
|
|
|
halp unreal engine takes too much code to do this |
|
|
o well ok bye roblox ill just use ue 4 then good luck with this problem other devs |
|

ima scat man bump bump bump bump
pls pls pls bump bump bump bump |
