Wow! Thanks for sharing your experience. When you say it renders slow, have you timed it? I noticed that if you work on a smaller image (like 600×600), it takes only a couple of seconds, but yes, if you are using an image the max size of 3000×3000, it takes longer. Maybe it depends on the details of the texture or the effect? Or maybe, you’ll find some textures that are worth the wait! 😉
Thanks for sharing anyways.
