fixed window sills in 2026?

[Angie15]

Have you fixed the window sill Z-fighting yet? As per my technical support complaint? 

No point offering ray-traying if it still ray-traces wrong?

I do not work for Chief Architect  and I am not technical support, nor do I have access to anything you sent technical support, nor am I a dancing monkey ..if you feel compelled to ask me in a nice way then I might take time out of my busy schedule to help you for free.
Let's start with what z-fighting issue?

• What sill are you putting on for exterior and interior?
• Does your window have a frame/sash?
• What settings are you applying?

I couldnt reproduce any z-fighting so I would need more info

Raytracing. What issue do you have with raytracing? it is working as expected for me

I found your old thread about sills. Install this and tell me if it fixes your issue:
Flat Sill.calibz
if it does, then let me know more specifics about the common sills you need.

Its really easy to replicate. In HD pro 2025. Draw an external wall or room, any wall doesn’t matter.
Increase the wall depth to about 400mm from center. 
Place a window, with external casing. (70mm)
recess the window frame by about 150mm
choose any default 2025 sill/shape profile and recess it. 
Bam z-fighting.
