[Music] in this video we're gonna take a look at the new shape extrude node so let's start by creating the node I'll hit the spacebar and I'm gonna do a search here for shape and you'll see we have this new shape extrude so I'll left click here to create an instance of this node now the shape extrude is going to render a shape here in my 2d view and you can see that well we have a shape and we have a little positioned controller here and as I move this around it's going to allow me to orient the shape here in my 2d view now we have some parameters here for controlling things like our extrude height as well as the extrude depth and here we have the extrude shape so by default you can use a base cylinder or a cube and then we also have this custom input here so I'm gonna set this to custom input to start and over here I have just a shape that I created and you notice that this is just a binary black and white shape and I'm gonna plug this right into the input here for the shape extrude so I'll double click and now here's the result you can see that we're using my custom shape pattern here for the extrude shape now again I can do things like play around with my extrude depth as well as the overall scale and then here in this section of sliders we have the ability to control things like the bevel height as well as the bevel intensity as well as the bevel curve so here I can make changes to that curve I can round out my bevel shape or I can move it in to produce more of an inward curve like this there's also a setting here for a mirror bevel so if I enable this to true you can see that we're just going to mirror or repeat that bevel on the other side of the shape I'm gonna set that back to false here for now so here you'll notice that we have this drop down for profile type and there are three options we have straight vertical gradient and mask and if we look at vertical gradient and mess these options are going to allow us to create a custom profile we can use for the bevel so for example let's set this to vertical gradient and take a look at how we can use a gradient to create our profile so here I'll hit the spacebar and I'm going to just create first a linear gradient and with this guy selected I am going to add a curve node to this as well and let's take the result of this curve here and plug that into our profile gradient so again we'll double click so we can see our shape extrude and this is what we're getting so now let's go back here to our curve and we can edit the curve to create that custom profile so I'm just going to left-click in here to start to create some keys and then just start to kind of play around here with the curve and you can see that I'm able to adjust these curves again to create that custom profile so that here we might go back here to the shape extrude and just look around and play around here with our extrude heiped and our depth and so on and then again like I said we're just gonna mess around here to create a custom profile that we want to use for our shape ok so here are just gonna use that curve here and then I can also again like I said come in and I can play around still with my bevel height as well as my bevel intensity value and also make adjustments here to that bevel curve again the profile that I'm creating here with the curve node is just allowing me to create that custom profile that I want to work with now there's also another option here and if we take a look underneath profile type you'll see that we have masks so when I enable mask you can see that we have this profile mask input and this was going to allow us to input a shape that we can use for this profile so what I'm gonna do for in this case is I'm gonna create here just an SVG node do this from from resource and we'll call this mask and I'm gonna set this to be grayscale so here I'm gonna use the pen tool and I'm just gonna create a shape that I'm going to that's going to represent this custom profile and when you do this you want to make sure that you create the shape here on the right side so again I have just gonna plot a few keys in here to just create a basic profile shape so I will just do something like this okay so here I have a shape that I can work with let's take the output of this shape and plug it into the profile mask and now let's take a look at our shape extrude and here you can see this is the shape that we're getting so again going back to shape extrude I have the ability to keep messing around with all of my settings again as I work through building up what this shape is going to be so here in this case I'm going to set my profile mask back to my vertical gradient and I think what I'll do is I'll just enable my bevel mirror and this is going to represent the shape let's say that I want to create so now one of the things that I want to bring your attention to is this output range and there is some settings here from 0 to 1 or negative 1 to 1 when the output range is set to 0 1 it outputs a 16-bit image where the center of the shape has a 0.5 gray value if we then set this to negative 1 to 1 we output a 32-bit float image where the center of the shape is black and the parts of the shape under the middle value have negative values this allows you to have positive negative values for the shape a good use for this setting is when you want to use your shape with the new shapes bladder node with the negative 1 to 1 range the middle of the shape will sit right on the surface of the background height so here I have an example where I'm taking the shape and running that here through the shapes bladder you'll notice here with the shape extrude my output range is set to negative 1 to 1 and so my shape you can you can see that that center value here let's double click to view this so here you can see that middle of the shape is sitting right on the surface here of the background height that I'm feeding into my shapes platter which is just this Perlin noise now here if I take my shape extrude and I set the output range back to 0 to 1 you can see the difference that we're going to get so again it just kind of pushes the shape upwards like this so if you want to be able to have negative values you're going to use this negative 1 to 1 option here and this is probably what you want to use when you're working with the shapes platter here going back to shapes platter we'll scroll down here to where I have my height and if I look at my height offset I can start to use this to push this down here into the surface so here in this case I'm going to set this back here to 0 to 1 for this demonstration and the next thing I want to talk about here is what this down scale multiplier is going to do so we have a bit of a limitation in this shape extrude node so for example I want to create a normal map out of this so I'm going to take my output and plug this into normal and then I'm gonna set this value up to something like say 64 and if we take a look you can see that we're getting a lot of artifacting here in the normal map so one of the ways that you can alleviate this is by working with this downscale multiplier so what I'm gonna do here is I'm going to select my shape and I'm gonna come back up here to my base parameters and I'm gonna set this output size to absolute and I'm gonna set this to a value like 2048 by 2048 here and then what I'm gonna do like I said is I'm gonna come back here and the shape extrude I'll scroll down and I'm gonna come down to this down scale multiplier and I'm gonna start to increase this value here and here we'll set this all the way to 2 so now that we've done this if I come back over here to my normal and I zoom in you can see that this kind of technique that I'm showing here does help to clean up the result that you're getting from this normal map now it's not perfect if i zoom in of course we can still see we have some artifacts and some issues here but you can see that we were able to clean this up somewhat and get a bit better of a result and typically what you're gonna want to do with this type of shape extrude is you're going to want to use this let's say like in the shapes bladder or something like that as well so going through the process of using this downscale multiplier in most cases is going to is going to work okay and these artifacts aren't going to be too big of an issue so now again I can come back here to my shape extrude and I can work with my position here and I can start to you know position this or orient this shape however I need to produce the effect or result that I'm looking for so that's going to close out this video on how to use the shape extrude the shape extrude allows us to take a binary shape like this extrude a shape out of it it gives us full control over things like the extrude and the bevel the extrude height depth the bevel we can also use the profile type as we've shown here to create custom profiles either through a gradient or something like the SVG node as I've shown here and then finally we can output this here to let's say something like a normal map but if you're going to use the normal just know that we do have a limit in where it's gonna create some artifacting so you'll want to come in here and use this downscale multiplier thanks a lot for watching and I'll see you next time
