Join Paul F. Aubin for an in-depth discussion in this video Editing a walkthrough, part of Revit: Rendering.
- In this movie, we're gonna take an existing Walkthrough and begin manipulating it. Specifically, we're gonna focus on the camera movements. So, if you watched the previous movie you may recall that as we actually played the Walkthrough, the amount of twisting and turning that we were doing, it almost made you a little bit seasick as you were walking down this path. So what we want to do here is start fine-tuning that and make it feel a little bit more natural. Now, there's a few ways you could do that. I'm actually in the Walkthrough right now so down here under Walkthroughs, Walkthrough 1 is active, and I'm looking through the camera, and I'm at Frame 1.
You could actually use any of your normal modification tools to modify this camera frame so I could use the Steering Wheel, for example, or I could Shift and Orbit if I wanted to. But there's actually an easier way to do this. So what I want to do is select the frame. You remember that's the only way to get to the Edit Walkthrough button, and that's what we actually need here, but I don't want to make the manipulations looking through the camera. What I want to do instead is go back to my Walkthrough Temp Site Plan View, and you may recall that this was the view we were doing a Plan View that we used to actually click and place the original Key Frames.
Let me zoom in so that we can see the path, and notice that it is still selected because we clicked that frame of the camera back in the Walkthrough View. Well, the Edit Walkthrough button is still here and when you click it now you're gonna see all these little orange dots appear along the path. Those orange dots are the Key Frames, and again the Key Frames are the places that I clicked when I placed this camera. Now, what we want to use here is this little pink dot here, which is the Target Point of this camera. So if you select that Target Point and begin to drag it, you can actually reorient the camera along this Walkthrough.
And so then what you do is you say use this button up here to go to the next Key Frame, and the camera will jump over there, and then you can adjust that Target Point a little bit, and then maybe when I step into this tower I might want to turn my head, and start to look in the direction that I'm planning to go. And you can see that this will take a little bit of effort to do this, but if you adjust the Target Direction of each of your Key Frames then when it interpolates between those Key Frames, it will start to feel much more natural.
So maybe by the time I get here, I want to start looking into the space, and then as I get closer to the end here I might want to start turning my head and looking at the wall of the reception area. And, let's click down here under Frames, and I'll type in Frame 1 and press Enter. You see the camera will jump all the way back to the beginning. Then I'll scroll back down and reopen the Walkthrough, and now let's play it.
I've got it selected. I need to go to Edit again, and let's click Play. You can already start to see that my head is turning a little more naturally. I kinda swooped out a little right there, but the only way I could really correct that would be to add another Key Frame. Here it feels a little better as I'm keeping my head following my path. So you can see it still needs a little bit of fine tuning, but that's the basic process that you'll walk through. You can go Key Frame by Key Frame.
You can even go Frame by Frame and make these adjustments, and kind of keep your head pointing in the direction that you think feels natural as you walk down the path, and it will make for a much more natural and smoother walk as we play the Walkthrough.
