I tried recreating the under-the-hood method shown here, and now it crashes the app any time I load. const createTexture = (image, time) => {
"worklet";
const surface = Skia.Surface.MakeOffscreen(width, height);
const canvas = surface.getCanvas();
canvas.drawPaint(Skia.RuntimeEffect.Make(WarpShader.source).makeShader([time]));
surface.flush();
image.value = surface.makeImageSnapshot();
}
export default UsernameCanvas = (props) => {
const inter = require('./Inter_600SemiBold.ttf');
const time = useClock();
const img = useSharedValue(null);
useEffect(() => {
runOnUI(createTexture)(img, time.value);
}, []);

I've been working on this for about a whole day now, I'm trying to convert my own custom noise shader (glsl/sksl) into an image which I can use for a displacement map. The only problem is whenever I try using the functions provided internally, such as
useTexture(),drawOffscreen(),makeImageSnapshot(), andusePictureAsTexture(), each one ends up with the same error:This is roughly how my shader is setup:
And I'm attempting to pass that image into here:
Is there any way I can possibly get a live updated shader to output to SkImage so that I can use it as a moving displacement map?
