The Value of Lighting Reference Models
the final ingredient for believable digital characters
what is a lighting reference model?
A physical representation of a CGI character, creature or object, built to replicate its shape, proportions, surface qualities and sometimes colours/materials.
why physical lighting reference models still matter.
In an increasingly digital filmmaking landscape, it might seem surprising that one of the most useful tools for creating a convincing CGI creature can be a physical model. CGI artists can create incredibly sophisticated digital creatures, but understanding how light behaves on a real physical form can be invaluable. A physical reference model gives the VFX team something tangible to photograph and film under controlled lighting conditions. Although the final creature may exist entirely within a digital environment, creating a physical version provides the VFX team with a valuable bridge between the real and digital worlds.
why not just use cgi?
A physical model gives artists a real-world reference for highlights, shadows, reflections, translucency, texture and scale. A physical lighting reference model is particularly valuable for creatures with unusual surfaces—scales, wet/slimy skin, fur, translucent membranes, teeth, eyes, etc. Some creature can look completely different depending on the direction, softness, colour and intensity of the light.
A well-made physical reference model become a vital link between the practical and digital sides of production.

What information do we need?
Clients often provide a digital asset.
Alternatively Stitches and Glue can 3D sculpt this for you from character or concept artwork.
Scaling - consider the size of the model, is it life-size or smaller for a distance shot? Or perhaps a larger model for a detailed close up shot.
What about surface textures and materials?
Whatever your requirements, we can help determine the best approach for your project.
