How To Create A Quad Sphere In Maya

hi everyone welcome back to digital dream box hopefully everyone's having a great start to our new year um today we're going to learn how to make a sphere from a cube in maya and how to get it as perfect as possible let's jump right in and get started all right so let's take a look at how we can make a sphere from a cube so to make a sphere from a cube we're going to transfer the attributes of the sphere onto the cube but let's take a look at the sphere first and maybe why we even want to do it so here's the sphere you can press f to frame in on it and if you look at the topology of it we have larger quads here that i'm just turn off the grid for a second larger quads here and smaller ones up here and then some triangles at the top and what happens is that when um your edges start converging like the way they do at the top where they start um becoming tighter you're gonna have issues with shading so i'm gonna show you what that looks like i'm gonna select this cube what's this cube the sphere eventually will be a cube and i'm going to hold down the right mouse button and i'm going to assign a new material i'm going to choose blend and then in my attribute editor i'm just selecting blend choosing color gonna drop down uh the value of it something like 0.86 is fine and then also i'm going to lower the eccentricity we want to really be diligent in checking our sphere okay and i'm going to turf on turn off wireframe shaded again and this looks alright but as i rotate this sphere um what you'll notice is that there's the shading starts changing a little bit as i approach the top of it right so you can see right here that's the top and that can be an issue for us right also uh when it comes to unwrapping this topology is not the most fun to unwrap okay so now let's take a look at how um that can be even worse so if i take this sphere and i smooth it you know i i subdivide it and now when i take a look at the top we have this like star-like pattern and this sphere is just three thousand if i were to even smooth it one more that pattern becomes even more clear right and we don't want that okay the other thing about i'm smoothing the sphere this way and something that i don't see a lot of people talk about is that this sphere is no longer perfectly round so i'll show you what i mean i'm going to select the sphere i'm going to add the lambert material back onto it so it's a little bit easier to see i'm holding down the right mouse button and going down to assign existing material and choosing lambert then i'm going to press f to frame in on it and now i'm gonna rotate and if you look at the silhouette of it as i um drag the mouse down around um as i orbit you can see that the sphere starts wobbling right now because we're planning to project onto a cube we want that sphere to be as round as possible so i'm not going to subdivide this way i'm actually going to delete the sphere i'm going to add a sphere back in but this time can press t on the keyboard to access the poly sphere options and i'm going to change this to about 200. i want it to be fairly round tab 200 can press enter and now we have a fairly round sphere and if i were to select it frame in on it and then now when i drag you can kind of see it doesn't have that wobble anymore perfect now let's create our sphere from a cube i'm going to add the grid back in for a second and just make sure i'm facing the right way it doesn't really matter but i'm going to add the cube in and i'm just going to drag it out there we go now to round this cube what we want to do is smooth it so um we can go into this one press smooth and we have the options and just going to bring it up to four we can go even higher than four by inputting the number but for now i'm going to do four when you do four it can be a little bit deceiving too because like it might look smooth at four subdivisions but when you go higher then you might even see issues so we'll smooth it at four and then we'll smooth it once more at a higher subdivision later just to make sure that this is working for us okay so i have the cube which uh is smoothed out i'm just going to increase the size of it okay press us the space bar and i'm going to go into the side view and if you look at this um this cube is fairly round but it's not perfectly round if i were to scale this up a little bit bring this over here actually i'll hold down x just to snap it to the middle i'm going to turn on wireframe and i'm going to increase the size of it and you can kind of see the silhouette of it doesn't match the round sphere that we have that we want to project from all right but i'm just going to increase the size of it so that's a little bit larger than the sphere you don't necessarily you don't necessarily need to do that but when you're projecting pressing spacebar to come back to here the perspective view when projecting um the normals will get reversed if we don't do that okay so first thing i want to do is open the outliner select the sphere so where i'm transferring the attributes from and then i'm going to select the cube next i want to go to mesh and go to transfer attributes and what i want to do is first i'm going to reset the settings i want to turn on vertex position so once definitely transfer the vertex position i want to transfer the vertex normal as well because that's what's going to give us a smooth look and the one other thing i want to transfer is closest along normal so select that one as well and that allows the um the edge flow to be a little straighter otherwise you get a little bit of a wobbly effect if the sphere you're transferring from is fairly low in our case it's fine but if really depends on the topology of what you're transferring it to and from okay so i'm going to hit transfer and then what i want to do next is just delete the history if i don't do that then the um cube you won't be able to move it and then i'm just going to pull this off to the side and i'm gonna tap the spacebar again right actually i'm gonna um press the spacebar again in here um let's move it back just so you guys can see now the silhouettes match so if i were to scale this right you can kind of see it matches all right so let's go back out to here and let's inspect our cue which is now sphere um i'm gonna give it the blend material so i'm holding down the right mouse button assign existing material blend and then the area i want to check is right here at the pinch point and also right here and the reason why you want to check right here is that if you don't transfer closes along normal you get a kind of a zigzaggy effect right in our case we did it so i already know it's it should be pretty good but um let's close the outliner turn off the grid and also isolate our object so there we go i'm pressing f to frame in on it and now i'm just going to rotate the sphere and make sure that everything looks smooth and then let's find the problem areas as well and check it so here it's looking pretty good there and then um here it's looking pretty good there as well so that's good um and you might want to check this yourself just to be really clear now let's check with a higher sphere um for now i'm just gonna hide this and i'm gonna go out of isolation and i'm gonna add a cube in again put my grid back in so i can see it and there we go now here's our cube and this time i'm going to smooth it i'm going to hold down shift hold down the right mouse button click smooth and i'm going to punch five in here or enter five i should say um all right and here's our object i'm just gonna increase the size of it and just bring it to the middle there we go don't need that large i'm just going to scale it down a little bit all right so now let's project again same thing um go to the outliner go into uh selecting the sphere first holding down shift or or in this case hold down control select uh the cube and under mesh transfer attributes and um let's go to just hit transfer there we go all right delete history and now let's check our cube pressing f to frame out in on it and i'm gonna give it the blend material all right and let's close the outliner again we'll turn off the grid we'll isolate our object press f to frame in on it and now let's inspect it so as i orbit around let's look at for the problem areas first right so as i rotate there you can kind of see or what you don't see is like any changes in shading so it's looking really good let me just try and find it again i've done this before and i've really like really looked for it so i already know it's pretty good but you guys might want to check yourself right so the shading looks pretty good there and then the center here right which i already know it's fine no major issues there so now what we have is um a sphere from a cube that has good topology good shading and it's round and those are the three things that we were looking for for um essentially making a quad uh sphere all right so that is how you make a sphere from a cube hopefully uh this has helped you guys out if it has don't forget to hit that like subscribe if you haven't uh that'll keep you up to date with our content and have a great day happy new year and we'll see you all very soon see you guys later [Music]
