How to create a floor reflection in SketchUp - Skill Builder

[Music] hey guys turn so not too long ago we released a video that showed how to make a practical mirror by taking a room making into a component mirroring it over and then you know putting a hole you could look through that would represent a mirror so when you actively moved through the model in Sketchup it looked like there's a real reflection happening in real time over there very cool it was it was a fun one to do and you guys seem like a lot a couple people in that asked could you do that with like a floor so if I had a reflective floor like a shiny floor how would I do that so I figured I don't know let's try it out so that's what we're gonna do right here so we're gonna hop in here and use this model it's on the screen to make a reflective floor actively reflective in Sketchup I don't know I don't know what the term would be maybe you can help me if you have a good idea for what you called this process where we create real ish well you know the thing we do leave in the comments down below and tell me what I'm doing all right now let's go ahead and do it so okay so I have this little kitchen here and see it's it's pretty simple I do the floor is a group my walls are group appliances a group it's all groups bunch of groups so first thing of course I'm gonna do is take it all and make it into a single component so we go ahead and make component I'm just going to call it room there we go and I'm gonna make a copy of it just use my modifier key and move to make a copy of it over here and I'm you scale right now pull scale down to negative 1 and then this is the simple part right this is what basically what we did before I'm gonna put it underneath there so that's what we're starting with is a copy of the exact same component underneath itself that's the simple part but obviously right now our floor is not shiny it is just that same material whatever that that material is on there that Marbley material so one thing we have to do is make this transparent so I actually see this room below inside so I'm going to go ahead and double click to enter this component now here's the thing I'm going to run into this floor has no depth is just a single surface and that's the way we want it that is correct that's how it should be but because the floor down here is also no depth I'm going to run into an issue when I try to potentially when I try to pick things if I double-click to enter this floor one of the things that can happen is as I'm picking I can actually get my other component down below so one of the things I'm going to do is I'm going to go up to view component edit and hide similar components hide rest of model is already turned on B and C this is showing up down here because this is not the rest the model mark was the rest the model and he's gone this is actually a copy of the component so I'm going to turn on hide similar components to get rid of that so I want to worry about what piece I am or I'm not picking on a double-click to enter my floor group here in steel I says just a single surface so what I'm going to do is I'm gonna grab my paint bucket bring up my color swatches you see have a lot of colors in this model and I'm going to pick this color so let's go show it to me right here now this is the only place I have this material in this model so that means I can double click on the swatch and I can actually use the transparency slider to make it more transparent if I had this in here more than once what I would want to do is pick it once so I'll come in here pick it and then actually modify and reapply it as a new instance like so because it's the only spot that I have in the entire model I can just use the slider with it select right now I'm gonna drop this too I don't want to drop it too much because I want it to look shiny not see-through so I'm gonna take it to like 80% and see how that looks so with that at 80% I can go ahead and exit my floor and exit and what's going to happen soon as I exit is my other copy of this components going to show up down below and look what happens when that shows up yeah well that looks way worse so what we're seeing right now is the actual backside of this floor down below because that is a hundred percent opacity and my others 80 percent the hundred percent is showing up over top of my transparent material so what do we do about that well fortunately well it's kind of why we're here I'm going to double click to enter into this component and then I'm a double click to enter into the floor again so right now the top floor is 80 percent so I can see through see the blue axes back there you can just make it out the bottom side is a 100 percent opacity back side of the default material so this material right now is this one right here so what I'm going to do is I'm not going to mess with the default material and I can try to make that more transparent like we did with this what I'm going to do instead is I'm going to create a brand new material I'm gonna come over here and pick a color I'm just using my mark or my color pencils to pick a a bright obnoxious magenta color and I'll apply that to the bottom that in itself did not help that's not not the solution I'm do now is I can actually change that to a hundred percent opacity reapply it and now it's see-through from this side but 80 percent opaque from this side real important one of the things you don't want to do when you do this is have materials pre-selected if I pre select I'm actually selecting both sides so I want to make sure that when I use the paint bucket I'm just applying that material to I'm applying that 100% opacity to a single surface just by dropping on they're not pre-selecting all right so what we've got now is we have a component with a floor that is 80% opaque on this side and 100% transparent on this side so if I click out I should get there it is there's my nice reflective ooh super shiny floor reflection using components and transparency inside sketch oh hi mark you will notice that mark is not in the reflection see that he's not down here below because he's not actually part of the component if that was important if we wanted to make sure we were reflecting mark also what I'd want to do is select him edit and cut go into this component edit paste in place and now if we come out here we'll see well this is actually gonna get a little funky because to make that work out right I'd have to get something like this so maybe best to not have my entourage visible through the window just to make this line up a little better so by mark there we go all right so there we go super shiny floor using just the native tools and because it's a component if I was to do something if I was to make a change so say I was to come in here and I want to move this light over like that because it's a component when I exit out I'll actually see that new light location in the reflection so hopefully you like that that's like I said a continuation of the one we did earlier but enough people asked I figured it was different enough because we had that material between and the window in the mirror is just a hole in the wall so I hope you learned something new from that if you did like that go ahead and click on the like button down below if you want to see more videos like this we release a couple videos like this every single week and if you hit the subscribe button down below you'll be notified every time we drop a new video most importantly though please leave a comment this video right here was created because comments on the previous video like making these videos a lot but we like them a lot more when they're showing something you want to see thank you you
