And as soon as I post the video, I got a solution for a seamless stair effect, go figure.
This time I let SLADE do its own PNG -> palette conversion (hence the striking color differenece) and Freestyle rendered the a line at the texture's border causing the extra grid effect, but I was mostly looking at the ridge "emboss", which seem to look better.
I also quantized the generated UV coordinate to fit the texture's resolution so there'll be less bleeding between texels, as an experiment.
I tweaked the last few days an attempt at getting a Blender -> SLADE workflow. In the screenshot both the metal beam and the (dielectric) wall is shown in the same time but the pre-rendered version had an alternative workflow that allowed me to add an area light over the metal bits to give them the distinct shininess that isn't present on the walls.
