Hi Goliard,

Yes, you can send me the file so I can tell you where the problem is coming from; it would be a pleasure :)

In the meantime, here's some advice for developers, because this is often what can cause bugs:

Keep in mind that an HTML file shouldn't exceed 100MB for what I would call a decent display, and 50MB for older browsers and systems. That's why the chaptering system with tracking to a separate HTML file was implemented.

Base64 encoding greatly increases the file size; a 1MB image then weighs around 6 or 7MB. That's why you should use .webp for images, which reduces image size by more than 90%. The same goes for videos and music... Really be careful, the file size increases rapidly; it's the technical limitation of encapsulation.

For easy and free compression, use Google's application:

But rest assured, with proper compression of images, videos, and audio, you can have around fifty images, background music, and a few videos for animations for a single chapter.

Hi Capsule Team,

I think the easiest method is uploading the test to my itch.io account so you can download it from there:

[UPDATE]

I substituted a webp background image instead of the original jpg and it worked fine... Something to think about...?! It would also be useful to duplicate a scene, or allow a background to run across several scenes - that would be efficient.

Hello goliard,

I'm glad the webp works !

As I mentioned above, compressing your images is essential; it's THE technical limitation of encapsulation. Furthermore, what's the point of using 4K or 2K for a visual novel? 720p displays perfectly well on a large computer screen. I even recommend, when compressing to WebP, keeping only 75% of the quality; that's more than enough.

Regarding repeating a background across multiple scenes, it's a good idea, but there's a technical issue: In the architecture (JSON), each scene is independent. If we allow an "empty" background to "keep the previous one," it creates a major problem for loading save files.

For example: The player saves at Scene B. If they load that save, the engine won't know what the background was in Scene A, and the player will get a black screen.

However, the "Duplicate Scene" feature partially solves this problem! By duplicating Scene A to create Scene B, the background image link is copied. This is transparent for the player, efficient for the creator, and safe for the code.

It's a good idea, I'll add it, thank you very much :)
