Kicad 9 Raytracing no good

What is wrong in raytrace (3-d view) in Kicad 9 (on mac). When active looks crap. See pictures. The blurry is when raytrace on.


Many times stuff like this is more about the system so it would probably help to add it to your opening post. Copy version info is the button you want.

What is wrong in raytrace (3-d view) in Kicad 9 (on mac).

Nothing wrong. That is the new IP protection feature. Kicad prevents you from publishing top secret electronic boards.

Do you have tried:

  • installing the latest most recent nightly version (kicad v9 is not officially released, it’s currently only a release candidate)
  • using the 3D-viewer command Preferences–>Reset to default settings
  • if you wok on multiple monitors: run only at one screen

As the raytracing looks good with most recent nightly on my system (Win10) it could also be a MAC-OS specific issue.

If the issue persists it could also be a bug. If you open a gitlab issue don’t forget all information mentioned by hermit.

Thanks. I found now it is a special thing in this project. I have a chassis surronds the PCB and when is set to 0 opacity (transparent) to be able to see the PCB in the 3-d viewer the render function goes crazy like this and make all blurry.

The issue sounds that it is setting the material to be transparent and your are actually see is a refraction and refraction distortion (“the blur thing”) of the material (like through a glass). I don’t know if that is supposed to be or not on that case, so may still want to rise the ticket issue.

We found recently some other bugs on raytracing related to Mac platforms. Looks there are something different while handling the floating point variables.

I think that this is by design - to accommodate rendering transparent enclosures.

KiCad has a lot of configuration options for rendering but you may be better off using Blender if you need to render in a hyperrealistic way.

It works good for KiCad 8.0.8
