[SOLVED] Webp images as textures

Good afternoon guys,

How can i use Webp file extension as texture for my models?
I have a system that depends on loading time and it will very important for decrease the size of my images

The first problem is that the Editor does not have .webp as a recognized image format. If you upload one, the Editor interprets it as a binary asset, not a texture asset.

Additionally, the engine’s image resource handler cannot currently handle webp images. If you do something like:

app.assets.loadFromUrl("brick.webp", "texture", function (err, asset) {
    if (err) {

It will print:

Error loading Texture: format not supported: '.webp'

It’s because of this line in the sourcebase:

Just need to add || (ext === '.webp') there.

But you should be able to do something like:

var app = this.app;
var image = new Image();
image.onload = function () {
    var texture = new pc.Texture(app.graphicsDevice);
image.src = 'path/to/brick.webp';

I’ve added a GitHub issue about this in case you want to track progress.


Working! I’ve tried to create the objects manually Image -> Texture -> Asset, but was conflicting with my code, so i override the function that block the Webp format. It isn’t the best solution but is only until the issue at GitHub to be solved.

Thanks for the help again!

In 2023,

It’s as simple as adding

pc.Http.ContentType.WEBP = 'image/webp';

before you try to load webp as a texture.
