Blender Quick Tip - Better Tires

this is how I used to render my tires I basically took the ground plane and then moved it upwards until it touched the tire and then continued to move it upward until the tire was slightly clipping with the floor and to be honest it works quite well and but today I have a better method that I want to show you and it's as easy if not easier than this so first you want to select your tire and make sure all the modifiers are applied let me just remove that do not spoil the punch of the video and then using shift s like let me turn on my my keys over here okay so using shift s you want to put the cursor in the middle if your tire is at the world origin like this one it's fine just do cursor to world origin or whatever works best I just want you to have the cursor in the middle of the tire once this is done we're going to add a lattice modifier to the tire and then a lattice object now you can see that my light is spawn here because I move the cursor so I can just move the cursor to selected and select the lattice and then shift s again selection to cursor and now we have our lattice at the right place okay so select the tire with the lattice modifier and then select the target object as the lattice we just added scale it on the x-axis in object node make sure to not go in edit mode because if I was to go in edit mode we could just basically scale the tire now I just want to scale the lattice object so in object mode I will scale the lattice until it fits the tire pretty much like that now go to the object data properties it's like the the window the lattice icon if you want in green over here and we want to add the resolution to the lattice so we have a bit more control points in those two directions it will be fine now and we want a lot of horizontal control points but I'll just crank it to that point it's Overkill and you won't need that much okay so now in edit mode of the lattice object sorry do not go in edit mode of the tire we don't want to touch our tires in a distractive way okay so I will select the bottom row of points of the lattice and then move it upward a tiny bit just like that and then do the same for the other rows or vertices until I'm happy with the the flatter and I can get now you can play with this for quite a long time um I won't I just wanted to show you how I do them and the beauty about this is since it's not using for example vertex groups or anything if the tire turns the deformation will stay there so it will stay in the direction of the ground now you could parent the lattice object to for example the break since the the brake caliper doesn't turn with the wheel so the lattice would always stay in that orientation but it will follow the wheel when it turns to the left or to the right now this method works perfectly fine for tires with chubby side walls or like very flat uh threads yeah sorry um four tires with bigger Treads now it becomes a bit more Awkward like okay I can show it to you it's not the perfect method but it should still work fine you may need to tweak it a tiny bit more so I'll just do the same thing add the lattice object to the tire then skid it in seal the lattice in object mode until it fits a tire just like this okay that's pretty good add some resolution to your lattice just like that and then go in attribute and now you can see I may have used a bit too much so I will press o on the keyboard to turn on proportional editing and then scroll with my mouse to reduce the radius of the proportional editing and now this can obviously be a great way to make like a very um old tires that just don't have enough air in them anymore or something similar to that let me just not clip them to the floor because this is why I made this video in the first place but yeah you can see that this one may need a tiny bit more but it always depends on the type of vehicle you use the type of tires obviously um some tires will deform much more than others and it depends on the situation you want but this method is very flexible and this is what you should look for when you're trying to improve your workflow you want something that will work every time that's reliable quick and easy to implement because now I can just copy the style and then go to my new project for example I don't know this tiny pickup truck okay so you can see that this track doesn't have doesn't have any tire at the moment and I can just paste the entire object over here I set my Pivot Point to bounding box and then I can parent um the lattice and the tire together because I'm not planning on animating this for now because if you were planning on animating this and you were parenting for example to the tire or to the lattice doesn't matter the direction of the parent link um and the tire starts spinning you can see that we have the flat end of the tire on top on the top side which doesn't make any sense it's the gravity in the force of the vehicle desk it's creating this flat side so it should always be on the bottom and that's why I suggested to parent the lattice to for example the break because your brake caliper should not spin like this okay so let's just place this real quick using alt D I will move the tires at the right place just like that set my Pivot to 3D cursor just so I can mirror them so out the SX minus one so they're flipped exactly on the right side now let's just hide those lattice and make sure that this is that's right place now I could definitely make this better um but you can do it much better than me I'm sure with that but this is how I use um the lattice modifier to create non-destructive um I don't know Tire bottoming Tire flattening call it whatever you want um this is how I do it and it's a damn great method now I'll see you in the next one peace
