@stewart Thanks for getting back to me! Iāve been for another look and Iāve worked out a few things. I couldnāt get the layers to show as coloured in Kiri itself, but looking at the generated SVG, I can indeed see colours!
They also show up nicely and automatically become different layers in LightBurn, which I use to run my laser:
What I have noticed though, is that when I select āmergedā to line all the slices on top of each other, the colour becomes white for all layers. Opening the file in Inkscape initially I thought there was nothing there, until I looked at file size, but reading the raw file showed me thereās data there.
Iām still looking at the code, but Iām guessing when āmergedā is selected, something about the height data could be getting removed before the height->colour code kicks in?
Thanks very much fo looking/working on this, itās really appreciated!
