In the README for WebPShop (a Photoshop plugin for saving WebP files) there is mention of a method for creating animated WebP files, but the method for producing such files is not described in detail. The only information given is as follows:
The Timeline data is not used; thus animations rely on layers for defining frames (set duration as "(123 ms)" in each layer's name), and they need to be rasterized before saving.
I labeled the layers with the naming convention described above, and chose File > Save a Copy...
Unfortunately, it only produced a regular (unanimated) WebP file.
What other steps are required to get Photoshop to output an animated .webp file using the WebPShop plugin? Thanks.
