Cinema 4D & Octane Tutorial - How to make a thin film bubble material in Octane Render

well here we go I have been getting some comments on my Instagram where is it about how I've been making these bubbly textures right here recently so I thought I would take you through how I do that with octane render octane material and see them before D so let's make a sphere this will be our bubble turn off render perfect segments 248 icosahedron I'll turn on the lines so you can see how we're doing and let me click up here and a displacer put that under the sphere change the height to 40 centimeters and the shading to a noise we can see displacer has affected it there and let's turn this global scale right up to 1000 and maybe this Y scale to 200 so now we get this blobby kind of bubbly shape that you know if it was a medium sized bubble you might get this blobby looking shape if it's a really small bubble it would stick closer to a sphere and it was a huge bubble you know you have much more elongation and Distortion so we'll just stick for you know the purposes of this tutorial to this size and see how we go with that maybe let's change the global scale to 1,200 a little bit more rounded and spherical cool so that's going to be our blobby shape our bubble and we can turn off and on to sue this so let's put a background plane in change orientation to minus Z move it really far back I'm gonna say 1400 in the Z or the Z looking good and let's drop it a camera sorry I won't use my shortcuts I will open up octane change this to octane render let's make it 720 by 720 square let's change this to path tracing just 512 so it's quite quick GI clamp to 4 great we should if I click this we should get nothing because there's got no lighting in here and that's all good but let me put a camera in so objects octane camera and then I'll zero out just like the camera I'll zero out all these values 0 0 0 and the Z let's put that to minus 800 so everyone can follow along the same distances yeah so now if I select look through the camera I've got that of course still got no lighting let me grab the plane and just scale it right up so it's at least filling up the background I'll select this F the focus click on my object sorry click on my object click on my object that I can't see in there let me just get some letting in there first so I won't shortcut so I'll go HDR HDR AI environment and select this image texture here I want to load in an image and just go to Google and I just searched free HDRI outdoors and you get loads that you can use I use something like this one here so I'm going to go find that one no now we've got some lighting now I can choose my focus select my object and the focus plane goes to where I clicked great okay now let me go closer to my object actually I didn't let me just stick to minus 800 what I want to do is change the focal length of my camera so instead of being 36 millimeters wide let's make it 80 mil portrait sweet so now change it back to a sphere got some lighting got the model for our bubble let me save that let me put a sorry I used the shortcut again materials octane diffuse material double-click on that I'm just gonna change this to black drag that to my background and just call it BG for background maybe rename it down here as well so this is a nice starting point so I'm going to show you a really basic simple bubble shader and then a much more complex one so the simple one would be materials specular I'll drag it to my sphere so we can see boom glass then no to editor choose fall off connect that fall off to film width then select the fall off change the mode to vector 180 degree and then we can play around with these but you know here you can see already we're getting this sort of refractive dispersive bubble type of look and that's pretty much it depending on our scene and where the background is if I drag this background closer you can see how it's affecting that specular look but that's just a really let me change out the six again just so us back to the defaults but I mean you know it gets affected by what's around it and if I turn on this display sir again you know we've got a nice looking bubbly blob and you might be happy with that that's it that's that's really the basic version nothing more than that but I will take you through a more complex shader and depending on what you're doing you know that might look just fine might look better I'll take you through something that might look worse but depending on which circumstances it might turn out better as well so let me take that shader off and start the complex bubble shader so I want to start off with a I've just got my shortcuts up here I'm going to use these but a a glossy material you can get it through materials octane glossy material I'm going to double click and this is going to be my noise I'll call it noise and I'm going to go to the node editor and funnily enough I'll drag in a noise I'm going to connect it to the diffuse so we can see what's happening it might also help if I drag that material to the sphere so you can see the noise happening there I want to change these settings to turbulence octave of 1 quite big maybe Omega of 0.7 and then change the projection projection drag that there I want this projection XYZ to UV W okay so we're projecting a bit better now I want a bit this noise much bigger than that so let's change these settings I'm going to lock the aspect ratio and make it five so it nice and big okay so that sound is I'm going to add something new now I'm going to build a sine wave let me just drag it to the diffuse so we can see what's happening with that too so I don't want to sign let me yeah I'm gonna I want a saw wave I want to also change the projection on this to the same XYZ UV W I'm going to make the rotation minus 90 I'll lock this aspect ratio change the scale to 2 and the y position to 1 so we've got like a gradient sup sine wave wave that will go up and down sort of like a gradient in and out like a wave what you can also do is it's not necessary I'm not gonna use it really in this I'll just show you you can drag in a gradient make the input so change this sine wave to go through the gradient and later on if you decided you want to add color like colored bubble color to this sine wave you can do that I am NOT going to add color so I'll just undo that but we can see this sine wave you know affecting it now and what we're going to do is mix both of those together just save that so I want a mix where's mix mix so I put that texture in there and that texture in there I'll connect it to the diffuse so we can see what's happening so now we've mixed both of those together let me see the amount want to change that amount mm-hmm maybe let me change it to 0.4 just so the noise is a little bit stronger okay so that's just so we can see what we're doing but really what we want is actually I'll drag this to film with and the film width we can see he's starting to affect with those sort of colored aspersions throughout there and so I don't really want it on the diffuse so now what I want to do now I've got that texture happening in the film width I want to change this pretty much to like a totally reflective ball so I go to my index change it to one that will change it into a mirror ball like it will reflect everything so now it's really you know showing this reflective chrome noise wave through that we've got going on so that's the start next so I'll save that cool so next I just want to create another glossy material and I just want this like a totally reflective material so what the opacity to 0.5 and index to 1 and what I'm going to do is me let me show you what that looks like I just drag it on there so it's pretty much like a semi-transparent reflective material and I want to mix those together too so let's put my noise on top and I'll just call this Chrome it's not really Chrome but I'm just gonna call that so it has a different name and I'll drag that to the material so we can see what's happening there I'm gonna go my node editor it's pretty messy actually let me just go to the float make this point seven say so the reflection is still there but the that noisy gradients showing through cool so next I want to just make a transparent object so the specular double-click opacity zero so that's pretty much nothing and then I want to make another mix object so into this mix object I'm going to put my see-through object and the other mix that i just created mixing the previous two let me call it call this noise mix so if I done that double that will click yep just didn't update the the name noise mix all good so what this is gonna be really messy so if I can find this mix material in here there's a octane mix yeah I can see that the amount is just in a float and let me drag this mixer working on on to the object so we can see so I don't want this just to be a float I want to mix everything I've put together now like we did with the basic version into a fall-off map and that's it can change these settings around to suit I usually maybe make this point zero two and can leave that at six but you know depending on what our scene is let's just leave it at six that's it that is so now we've got this sort of oily detergent looking surrounding to our bubble I turned back on the Placer to you know if we had a fairly large bubble that we've blown it might look something like that and we just want to adjust the shader dependent on the size of our object so if I go back into the original noise one that we made and I say well instead of a scale of five let's make it a scale of 12 so it's increased the size of that and that might be a little bit more to our liking if it's a smaller size bubble and once again the displacement and because we've got the displacer on that's hooked it to some animation so if I put say 0.2 animation speed into that displacer let me get a bit more frames in here drag this out press play you can see how it's moving the bubbly blob to have some undulation that's it guys that is my bubble shader and because it's a bubble it's just reflective and dispersive the look is very much determined by what's being reflected its surrounding so if I grab a different HDR I let's say this bright snow-capped mountain it has a much different effect on it or if I grab so this night laser scene yeah that looks very nice and different too if I grab this sort of basic gradient sky gives me that if I turn off the background you can see it blends through so let me get a different background again just to show some variation what else have I got mmm just might not work but let's try it yeah so you can see background is pretty low quality but if we put a background image in the back there you see how that would come through and the edges would still be dispersed seeing like a bubble or if I wanted to drop in a studio rig which I made before we can see what it looks like with some lights and a background to it and I've got a separate tutorial on how to make that basic Studio rig if you'd like to so that is it guys hope you enjoyed it I hope you learnt something and let me know Cheers see ya
