Particular Assembly4 model fails to render correctly about freecad-render HOT 5 CLOSED

@howetuft you always have the answers!

You found the two important differences between my two models which I failed to see.

Thanks very much.

Hello,
I can't download the files from your links: could you please check? Thanks!

Thanks for looking.

That was a copy and paste error. Try again.

Hello,
First of all, I don't have Cycles on my present computer, only LuxCore, so my diagnosis is only partial at this stage (I will only be able to take a closer look in a few hours).

However, I think there is at least an issue with the GroundPlane.

In terms of position, your ground plane cuts your assembly, so the rendering seems clipped. If you shift the ground plane by -12mm (GroundPlaneZ parameter), the whole model appears. However, with LuxCore, the ground plane is black and the rendering is burnt.

Alternatively, if I removed the ground plane, everything is ok - except there is no ground plane.

Do you get the same results with Cycles?

OK, I got back to Cycles, and I figured out what was wrong, 2 things actually:

1. There is an 'LCS_Origin' in the Assembly, and this component makes the generated ground plane infinite. You have to hide this component (right-click, 'hide selection' ; or space bar).
2. The ground plane is not well positioned in Z, according to your model. It must be placed at -12 mm (GroundPlaneZ parameter).
   This being done, it should work. In any case, I get a more satisfactory result:

Just let me know if it is ok for you too!
