Editing walkthrough camera direction

“

- [Tutor] In this video, we're going to begin adjusting our walkthrough camera. So we're going to focus on the direction the camera is looking in. So as we progress down the path of our camera, sometimes it is looking off in odd directions, and so we can definitely correct that. So the first thing that we're going to do is select the crop region here of the camera. And this is how you access the edit walkthrough button. So that's a little non-intuitive at first, but just remember that that's how you get access to the edit walkthrough tools. Now, when we do that, we'll get our walk tools and our play button, so why don't we play the walkthrough and see what we're dealing with here. As we start down the path, everything looks fine until we start to approach the tower and you'll notice the tower is kind of out of frame, so that's a little unnatural. And then as we pass through the tower into the portico, it starts off okay looking down the portico, but then we kind of drift off to the left there, and we're kind of looking away from the building, which doesn't quite feel right. As we turn the corner and into the lobby, things correct themselves and it's not too bad, but we could certainly make a few adjustments there. And then of course, when the walkthrough is complete, it just resets us back to frame one. So now that we've kind of seen what we're currently dealing with, how can we make adjustments to it? Well, I'm still in the edit walkthrough mode here and I've got my frame buttons up here. So I could advance one frame at a time. I could go one key frame at a time. And one option that you could do is to work right in this view port, and you could use this fly button over here on the navigation bar. So the way that this works is you just sort of click this thing and you get this little cursor on screen, and then you just sort of mouse around in here to adjust the direction that your camera is looking at. Now the advantage of this method is that you're seeing exactly what the camera is going to see while you're making that modification, but you will have to go key frame by key frame in order to make those adjustments. Now you're welcome to try it that way, but I'm going to show you an alternative method. So what I'm going to do is switch over to a floor plan. So I'll go to my walkthrough temp floor plan. This was the original plan that I used to create the path. Let me zoom in slightly here and notice that the walkthrough is still selected, but it kicked me out of edit mode. Now it's really important that you keep it selected. If you click away from it, it's going to go away, and then you're not going to have any way to select it again from this view. So if that happens to you, just click back to the 3D view, click on the frame that will re-select it, then click back to your site plan, and it will be selected. Here in this site plan view, you want to click the edit walkthrough button. So once I've done that, you're going to see some red dots appear on the path. Those are the points that we clicked to create key frames when we first placed the camera. You'll also see the camera position where it currently sits. Now I advanced two key frames, so it's sitting on the third dot here. Now I'm going to back up one key frame, so I'm going to go previous key frame to right here, and this is where I used that fly tool to make adjustments to what I was looking at. Notice the little pink dot here, that's the target for the camera, and we can simply drag this to adjust what the camera is looking at. So if you just sort of look at the cone of the camera, you get some idea of what it's going to be looking at, and in this view, you can advance key frame by key frame and make adjustments to what we're seeing. So remember here when we rounded the corner, the tower was kind of falling out of frame? All we need to do is sort of turn our head like that. So I like this method because it makes it really easy for us to focus on what we're seeing here. Now maybe when we start getting close to the doorway, we want to actually start turning our head and looking into the space there, and then same thing with this one. And then as we move in here, these weren't too bad, but I'll just fine tune them just a little bit to kind of ensure that we're looking at something that seems logical. And this will all be interpolated as we go. So we're doing the key frames, but the in between frames will be adjusted proportionally. So let's just play that now and see if we've made any improvements. So I'm going to click back to the camera view and we're at the last frame here. So let's click in the frame field, type one, press enter. That'll reset us back to the beginning of the path and then look for your edit walkthrough tab, and click that, and that should give you the play button. And then let's just click play and see how we did. So notice there that we're seeing the tower a little bit better this time. Now here, we're still kind of taking a little bit of a curve along the portico. And as we move into the lobby, maybe our head turns a little too quickly, so you could certainly fine tune and adjust that, and there are some other adjustments we can make and we'll look at some of those in the next video.
