We will now morph a triangle to a more advanced shape of a rocket. Step 1: Now you know the basics of morphing, you have transformed the rectangle to a triangle.

If we choose to export from after effects, it would not matter in small projects, but it can take a long time depending upon the settings in large projects. Step 12: Now, we will use a media encoder to export since we can keep working on the project while the encoding and rendering will happen in the background. Step 11: To view the final render, we can either export it from after-effects or use an adobe media encoder, a separate program used for encoding and video rendering. After moving the timeline to about 1-second, press N, which will reduce your work area, and you can repeatedly test without clicking the timeline to zero. Step 10: After adjusting the path of the rectangle as a triangle. Then move the slider to 20f and adjust the shape of the rectangle to the triangle. Step 9: After ungrouping, set a keyframe for the path attribute at around 15f on the timeline by clicking on the stopwatch icon, and it turns blue, which means the key is set for the frame selected in the timeline. Step 8: Now ungroup the rectangle shape to get the path to animate and rename the shape layers triangle and square, respectively. Step 7: This is the important step to select the path of both layer and convert to the Bezier path. Press T for transparency, from which you can directly change the opacity. Reduce the opacity of both shapes so we can see the path to modify.

Also, set polystar path 1 points to 3 so we get a triangle.

Step 6: Now select the polygon tool and match its size to rectangle, and center everything aligning both square and triangle to the composition. So when we do animation, the transitions are calculated from the center. You can press ctrl to snap to the center. Step 5: Now select a rectangle tool or press Q and create a square by pressing shift and if the anchor is not in the center, then select pan behind the tool and adjust the anchor to center. Step 4: After creating the solid background, click on the lock icon and set the shy switch to on so that we do not accidentally select the background.
