Hi! I’ve encountered a bug (I’d assume). It’s not something that prevents anything, but when you first apply a material added to your project from marketplace, engine freezes for few seconds, and nothing happens. Then you apply it again, and it work. I hope this will get looked into. Thanks!
Sorry about that. This is sort of expected behavior right now, but we’ve been discussing how to handle this better. What is happening is that the editor is optimizing the texture for your platform at the time when it’s first loaded. That optimization can take up to a few seconds depending on the asset. It will only happen the first time – for a texture, the compressed representation of the texture is stored in the engine’s “derived data cache” and quickly loaded from there in future sessions.
