I have a comp that uses the Fetch Image node to randomly select an image from a folder of images (the folder being the List Files node set to File Type of Image). When I trigger that configuration to randomly choose an image (by sending an event to the List Files node) it displays nice and fast - even with the folder containing a good number of images (hundreds at least).
But if I try to use the Fetch List of Images node to define a specific list of images from which to choose, what's the best way to trigger a fast selection/display from that list ? I initially had the Fetch List of Images node connected to a Render Image to Window node. In this configuration it seems that it is necessary to send an even to the Fetch List of Images node in order to trigger a new selection from the list - but the selection seems to be very slow - even for a list of only 30 or 40 image URLs.
I could break the image sets into separate folders and use "List Files" etc. but that won't be so efficient in terms of disk space because in this case a given image is likely to be used in multiple sets/categories that I will want to be choosing from and so I would need to maintain duplicate files. What's the most efficient way to choose from a list of images ? Thanks.
