Make relights of our footage without needed any render passes. It’s especially useful when we try to illuminate smoke or atmospheric elements.
An important thing is to adjust the amount of emboss well, depending on the incident light it will have to be negative or positive. we can also adjust the smoothness of our emboss. I hope you liked it.
Here you can see a video explaining how to use it, you may find a more updated version on nukepedia or github.
In Nuke, normals are a type of data that is used to represent the orientation of surfaces in a 3D scene. Normals are typically used in 3D rendering and compositing to calculate the lighting and shading of surfaces, as well as the interactions between surfaces and light sources in the scene.
When using 2D relighting in Nuke, normals can be used to improve the accuracy and realism of the relighting effect. This can be done by using the normal data for a 3D scene to calculate the lighting and shading of the surfaces in the scene, and then using this lighting and shading information to adjust the colors and intensities of the light sources in the 2D relighting effect. This can produce more accurate and realistic lighting results, as the lighting and shading of the surfaces in the scene will be based on their orientation and interactions with light sources, rather than being determined solely by the colors and intensities of the light sources.
To use normals in 2D relighting in Nuke, you can use the Normalize node to extract the normal data from a 3D scene, and then use the resulting normal map to calculate the lighting and shading of the surfaces in the scene. You can then use the lighting and shading information to adjust the colors and intensities of the light sources in the 2D relighting effect, using color correction and grading nodes such as the ColorCorrect or Grade nodes. By using normals in this way, you can achieve more accurate and realistic 2D relighting effects in Nuke.
«I have not failed. I’ve just found 10,000 ways that won’t work.» – Thomas Alva Edison
This quote is often attributed to Thomas Alva Edison in reference to his efforts to invent the light bulb. Edison is known for his persistence and determination in the face of failure, and this quote reflects his attitude towards his work. Despite facing numerous challenges and setbacks in his efforts to create a practical and reliable light bulb, Edison never gave up and eventually succeeded in inventing the first commercially successful incandescent light bulb. This quote is often used to encourage people to persevere in the face of challenges and setbacks, and to remind them that failure is an essential part of the learning and innovation process.
