Create custom Sand Dunes in Cinema4D - Easy tutorial.

we need a straight line so let's create a helix and remove its rotation set the subdivisions to three bake it down by pressing C add it into a cloner let's start with five lines bake it down and add it into a loft the order in which the splines lay is important so let's organize it from the middle outwards now you can start arting go into point mode and go crazy by rotating the points you can create interesting curving shapes duplicate the mids spline to get a sharp Ridge look at that perfect Dune oh maybe not keep moving points around until you're satisfied remember that the Middle Ridge now has two points so make sure to select both of them you can add more geometry by going into the Loft and adding some subdivisions okay now we have our basic Dune let's put it into a n and let's subdivide it some more it's looking a little bit too perfect now so let's add a displacement modifier place it in the group and put it before the subdivision let's put some noise into it noise makes everything better go into the object Tab and change the direction to planer we will keep it at the plus X open a Fields Tab and drag the mid spline into it go into layer and change the spline shape into mosque you can play around with the distance here now you have full control over where you put the noise based on the ridge let's play around with the noise settings because right now it looks horrible I want to try and just jiggle up the edge a bit and increase the fall off if you need to add as many noise displacers you want you can just duplicate a displacer and play with different kind of noise let's make it into an actual sand dune made with a sand material I'm using a wavy sand texture here to get some more detail into the dunes the octane displacement is doing most of the heavy lifting here and there we go a dune and now that you have everything set up it's very easy to just move points around in your camera view if you want to have more points just cut your line up with the knife tool since Dunes are formed by the wind let's add some smoke simulations select one of your mid splines and create an instance of it drop it below the displacers place the instance in the sweep now we need a profile let's add an anide and put it into the sweep this will be the Pyro source for the smoke you can change where you want to spawn the Smoke by changing the start and end growth if your geometry looks ugly you might need to add some more interpolation into R spline select the sweep and add a Vertex map go into fields and let's add a Shader field let's put some good old noise in there make it a bit more contrasty and why not animate it as well select the sweep and let's add a pyrometer on it ah yes the self igniting Dunes add the vertex map into the emission map to get some breakup on where the smoke spawns add some Wind by searching for it pressing shift C I can never find it up in a panel give it the direction you want to wind to blow and maybe we need to add some more wind strength and add a bit of turbulence into that wind as well if you press contrl D you can find the simulation settings here you can lower the voxel size to get a more detailed smoke simulation I would recommend increasing the substeps if you have a lot of wind we can also go into the emitter and disable the temperature we don't need it here and there we have it a single art directable Dune
