Yeah, that’s the texture streaming. I don’t think there is an “on finished loading” event you can bind to, unfortunately. My question is, what is the resolution of your spirtes? It looks like you are going for a pixelated look, so the textures could be small. You probably noticed that you don’t scale up the textures, they look blurry, so you scaled them up, right?
This may sound unrelated, but bear with me and please respond.
