I have a project where I am making several GOBO's / slide maps to add to my spot lights. I have read over the documentation online and everything works great, but I wanted to know is there a preferred image format, file dimensions, or image ratio? I have been exporting black and white with Gaussian blur added to soften, 3000 x 3000 px jpegs and applying them and they work fine but did not know if they have to be 1:1 ratio and is 3000 x 3000 to large? I am assuming it would be the same as texture creation, the larger the file and resolution will create better results? Is there documentation for exact specifics on preferred files? Thanks in advance.
