#NUKE 10 SECONDS AFTER FIRST LIGHT LICENSE#

- I have a license for FaceBuilder in Nuke, do I need another license for FaceBuilder in Blender?.If you don't know camera settings for all photos, it's better to use Varying Focal Length Estimation. Though you should not forget to setup the connected Camera node accordingly - it should have keyframes with proper settings for each frame. Starting from the version 2.1.0 - yes, you can. - Can I use FaceBuilder with a set of photos with different resolution or different focal length?.

Using the statistical data FaceBuilder tries to find an optimal shape for the 3D model so it would match the disposition of all pins.

- What actually happens when I drag pins?.

FaceBuilder uses camera settings and pin positions to change the shape. No, they're only being displayed for you as references.

- Does FaceBuilder use the photos in any way?.

In some cases it can help with visibility of the mesh and handiness of the pinning process.

You can connect an image node that will be used as a texture for mesh colouring. Note that if the video was shot with a zoom lens and the focal length is changing but you don't know the exact focal length for the frames you want to use - it's better to use Varying Focal Length Estimation in FaceBuilder. Sure! Just don't forget to set up your Camera node properly.

- Can I use FaceBuilder with a video as a source?.

If you don't know what camera and focal length were used, you don't need to connect a Camera node, but instead switch on focal length estimation - then a default Nuke Camera node will be used, later you can export the estimated camera as a Camera node. The essential parameters you need to setup are: focal length and vertical/horizontal aperture (sensor/film-back size). The quality of the model will be better if you use a Camera node that will reflect the settings of the camera used for making the reference photographs.

- Do I need to connect a Camera node to FaceBuilder?.

You need to create a Read node, load your photographs as a sequence in it, and then connect the Read node to 'bg' input of FaceBuilder.
