So my next step was to export VRML and STEP file models from KiCad. Unfortunately, KiCad raytrace option does not allow us to set lighting, floor and other scene parameters, hence Blender. There are multiple light sources (multiple shadows), and the scene looks washed out due to excess light. This is the bottom of the PCB, so the “floor” is not visible, and the overall render looks darker than expected.Īs a comparison, here’s what the top view looks like. Normal 3D view from KiCad Ray traced render from KiCad – bottom side KiCad’s in-built ray-tracer does a decent job, but there is no way to adjust lighting, background and other parameters. I started off with the Open Hardware Summit 2020 badge (which I had a bit role in designing). Blender render #1 Blender render #2 Blender render #3 Blender render #4 Blender render #5 Within a week of dipping my feet in the shallow end, I made these few renders. My aim was to learn how to do photo-realistic renders of KiCad boards. I’ve been putting off using Blender since over 5 years, being intimidated by the complex UI and workflow, until this month when I mustered courage to go through Andrew Price’s Doughnut tutorials.
