Output of the Up-Res node. Original image (left) and results of Up-Res 4x (right).
The Up-Res node can be used to significantly increase the resolution of an input image while preserving content quality.
There are two types of the Up-Res algorithm to choose from - Toon and Photo. Toon produces best results for stylized or hand-painted content, and Photo is best for realistic inputs.
The node can be used with both single textures (Bitmaps) and Materials.
Here are the steps for applying Up-Res to an image:
Choose the multiplier at which Up-Res increases texture resolution. The choices are:
