Arnold Tutorial | Spider-Man: Into the Spider-Verse Cartoon Material Highlight Section
In this article, Fox Renderfarm, a leading render farm and cloud rendering service provider in the computer graphics industry, will present an Arnold tutorial for the cartoon material highlight section of Spider-Man: Into the Spider-Verse.
The Process and Effect of the Highlight Section
Create a directional light.
Create an aiToon node as the base node for the Highlight section. Also, create a ramp node as the Mask. Connect the ramp node to the Tonemap under Base in the aiToon node.
Drag the weight range of the black and white areas of the ramp node closer together, and set the aiToon Base Weight value to 1.
Next, create an aiRange node, and connect the Out Color of the previously created Highlight_aiToon to the Input of the aiRange node. Then, create another ramp node. Connect the Out Color R of the aiRange node to the position attribute of the ColorEntryList[1] in the new ramp node.
When the newly created Ramp node is selected, you can see that the selected position is highlighted in yellow, indicating that colorEntryList[1].position = Selected Position.
Also, change the Ramp Type to Circular Ramp and set Interpolation to None. By moving the position of the black and white weights (as shown in the image), you can see a white circle.
Create a projection node to project the white circle onto the model from a perspective view. At the same time, temporarily change the Repeat UV value of the ramp node to 150 150 and Rotate UV to 45.
Then create another aiMixShader, and connect the Out Color of the projection node to shader1.
Simultaneously, create another reverse node and connect the OutColor of the aiToon node to the Input of the reverse node. Then connect the OutputX of the reverse node to the Mix interface of the aiMixShader. Finally, render to see the effect.
It seems the rendering was inverted previously. Let's go back to the ramp node, invert the black and white, and then render again. It should be corrected now.
This concludes the tutorial's major section. I hope you found it useful. You may wish to consider using cloud rendering services such as Fox Renderfarm to speed up the rendering of your project in order to maximize Arnold's rendering speed.
