Vellum Balloon Text in Houdini

hello everyone and welcome back so in this video I'm going to show you step by step how you can create this balloon text effect using Alini and vum so let's get into it so with the fresh Alini scene let's start by dropping a geometry container and font and I'm going to write CGS for CG sides and I'm going to pick a different font that has some rounded Corners so let me pick the [Music] font so this is the font I'm going to use is a bit more rounded and it will work better for the effect so let's ex R it and we will extrude about2 and output the back then I'm going to create um VDB from polygons so we can round it because right now it's just too sharp we can bevel it but it will work better with the with a bdb conversion bdb from polygons and let's say [Music] 0.01 and now we will smooth it out so let's first convert VDB to polygon so we can check the final result so as you can see it's not looking great that's SM SDF and now it's looking better let's say we want 10 and after the smooth I also want to erode it so let's put down a reshape and let's erod it by something like this should be fine so we're going for from this to this and now this geometry is not the best for simulation let me just save this quickly so as I was saying this geometry is not ideal so we will remesh and let me check the amount of remesh I used so point 075 this should give us enough resolution and now we can start our vum simulation so let's just organize this and put down a vum configure balloon this will create the vum clots and the pressure constraint and let's create a valance solver and if you hold down J you can drag and connect everything now just wait a bit and let's check the results and this will fall down we will need to remove the gravity so let's remove the gravity and we will need to set up some things in here so to start with let's go to our vum cloud and what we need to do is to play with the wrestling scale of the stretch so in this case I use1 1.18 and let's see what that gives us nothing too much and we will also so increase the the stretch to 10,000 and while we're here let's decrease this the band stiffness to point1 let's see what it gives [Music] us that is giving us this result which is a bit too much and not very controlled so what we can do is to play with the volum pressure so let's go to the vum pressure and we can say the wrestling scale let's try [Music] 50 and we will just use one frame so we could actually use just this Frame the previous one so as you can see we already have the effect this one is a bit too much in my opinion so we can use this one as you can see it's creating some nice wrinkles in here and here so I think I'm going to use this one and now let's create a Val iio to just to to break the result and we will remove time dependent cat cache and just save to dis now we can just have it fre the frame freezed so let's create an all just for demonstration purpose I'm going to render this out so we can go to Solaris and it sop import and let's import the geometry something like this and let's create a material [Music] library and inside let's do a c material Builder let out of few and assign to everything now we can create a dome light oops dome light and let's say it's a light long and I'm going to use Christmas photo studio from hdri Evan or poly Evan I mean and let's create a CA settings let's change to xpu give it some quality and we can increase increase the diffuse limits Reflections and refractions is fine let's test this out [Music] kxp and let's get rid of the background so display environment lights as backgrounds turned off let's change it to dark let's go to render and save view part size that way if we have a camera we won't render the full resolution but just the portion of the view part so but in this case I'm not even going to bother creating a camera just going to do a simple material so let's change this to some orangey and increase the metalness and increase a bit the roughness so yeah guys it's basically it nothing to complex as you can see it's just really easy to set up and I hope you have learned something new let me know in the comments and I'll see you soon thank you
