I am using the default scanline renderer with a skylight projecting a HDRI and I notice that my bump map doesnt seem to be very prominent. By default i had it on 15, so i tried a value of 150 and re-rendered and it seems identical. Has anyone noticed bump maps are not working properly with light tracer? or is there something you need to do to enable it?
Found out i had to use Advanced Lighting Override material and set the indirect light bump scale
Even at 1%, you can't see reflections, but somehow the bump manages to show up.
Maybe an idea.
on both materials i also threw the bump map i was using into the Displacement slot, which normally has some pretty wacky results, and nothing happened.
i also tried as RosaKiddy suggested, and put a directional light into my scene, with shadows turned on - this also didn't make the bump map visible.
i can safely say that i have no idea what's wrong
