Cheap art will be just that. The true value lies in commitment and hard work. This is just a tool and without a creative mind operating it the results will hold no magic. Did photography kill painting? I think both are doing and developing rather well.
Minutehour shared a filter that processes an image to have craquelure similar to “Italian” pattern craquelure. The tool provides a great way to upscale small images intended for 3D environment production as it adds a bit of depth and detail to the overall processed image, generating Normal, Height, Roughness and AO map as well.
All example images used are artful divinations of Zhillustrator, so if you like those be sure to check his Artstation site for more of his fantastic artworks.
To use it you would need Substance Player, freely available at Allegorithmic.
