Thank you so much for the reply. I've tried to follow your advice, but can't seem to find a way to adjust normal and height parameters in Painter (it seems that materials made in Alchemist don't allow control of these parameters once imported to Painter). The only way I've found to adjust Height is by using a Height Adjust Filter, but the result is still far from the original one in Alchemist.
Another example: I made this material in Alchemist (see attached pictures), and then been trying to use it in Painter (with Height Adjust filter), but again, can't make it look exactly as the sample in Alchemist. There's a truly photorealistic quality that gets lost once imported in Painter; if you look at the screenshot from Alchemist, you'll notice that the material looks sharp, detailed, photographic; whereas once applied into Painter, tends to look a bit blurry and undefined. I wonder if there's a way to get the exact same results in Painter than in Alchemist, or if some loss of information is to be expected… Again, thanks in advance for any helpful insights.
