 The bit depth of the images that you use in Lys have a large impact on the quality of the processed maps. Unfortunately,​ 8bit images have extremely low precision due to the relatively small number of values that can be represented per channel. The bit depth of the images that you use in Lys have a large impact on the quality of the processed maps.

-As a result of this limited precision, it can be difficult to reproduce variations of angle and slope with acceptable accuracy. This limitation of 8bit height maps may become apparent in the form of banding. These artifacts may not be immediately noticeable ​on Normal maps, however they are still present and may reduce the accuracy and fidelity of Lys’s output.+As a result of this limited precision, it can be difficult to reproduce variations of angle and slope with acceptable accuracy.

 We recommend that you use the highest bit depth possible in whatever source images are to processed by Lys. If your current pipeline is restricted to 8bit, you can export the final map as 8bit from within Lys once the processing has been completed. You will always get more accurate results by authoring source images in higher bit depths and only converting to your target format (eg: 8bit) during Lys’s export. We recommend that you use the highest bit depth possible in whatever source images are to processed by Lys.
