I have a project providing random access to five scenes. In order to avoid bogging things down at the start, I’ve set the background images for all but the initial scene not to preload. When setting the transition to dissolve, triggering the dissolve does not trigger the complete scene load, so that…

Maybe switch the backgrounds to vector artwork (SVG) or compress the artwork with imageOptim. (Also, SVG can be compressed with SVGOMG.) That’s probably not the answer you’re looking for, but it could significantly reduce preload times, allowing you to load all the images at once. Searching the web…

var img= new Image(); img.src = fullImgUrl; img.onload= (function(e){ //your hypeSceneCall ... }) create a loop if it’s more than one image … if loading is suspect to take some time -> show some preloader on meantime :slight_smile:

I’m not going to try and guess what Santa has in his bag for the next release, but I am looking to see if I can make out the shapes of a shared resource folder and and scene-indepe…

Hi Hans. So, for example, I could attach a script to a keyframe and load large images (such as various background photos or the first few images of a slide show) in the background… I understand the generalities of JS from my background in Lingo, so I can make out your example. I would need to simpl…

you wrote that you load the scenes randomly, so there must be a js-function that loads a scene. just wrap the call with my lines above …

[image] TYancy: I'm using the web output tools in Photoshop to achieve the ideal balance between resolution and size. Not surprisingly, I too have used Photoshop. The web exported images can still be compressed further with ImageOptim. It has "Lossy" and "Lossless" options. The "Lossy minific…

Thanks, Michael. I’ve got it, but I’ve never run side-by-side comparisons.
