The first one consists in using the animation sequence by animating the albedo of a material component. You can find the documentation about the animation sequence here 3dverse Documentation — Cloud-Native Real-Time 3D Development Platform
Tips:
Keep in mind the x, y, z = R, G, B
Our x, y, z values are normalized, meaning the value has to be between 0 and 1 versus 0 and 255. You will have to do the conversion.
It only works with a Material Component (not with a Material reference)
