@Sergei_Pakhomov I did what you said but then I realized that it didn't match the colors I had planned for the final scene. So I did the opposite of what you said XD, I have enhanced the colour of the gold and although it looks like a thin layer of silver now it doesn't attract so much attention.
@Moki07 You mean the Clipstuido program? I have it for windous and it's really good for drawing (to make pencil strokes, ink is much better than photoshop) they usually make very good sales along the year, look at it because it's really worth it. When it comes to making very precise details like these watermarks it is much better than Substance Painter.
This is a real time rendering test in Substance Painter.
