"Number of points in ill files doesn't match the number of points in point files" error


Hello everyone,

I’m testing dynamic shading for a small office room, I encountered this error: “Number of points in ill files: 105 doesn’t match the number of points in point files: 140”. See image below. It’s worth mentioning that I had Windows permission issues (user permission to access the Ladybug folder), I don’t know if this caused the mismatched point count issue.
Here are the files One_office.3dm (76.9 KB)
Dynamic_Shading_Dis_rev5.gh (660.4 KB)


@RaniaLabib, can you share the zipped folder? It’s hard to say without checking the files.


Hi @mostapha, I’ll do that when I go back home to access my computer, in the meantime I found out that my points were split among 3 .pts files, so I have 3 .pts files in the folder. Is this typical?


Are you using 3 CPUs? Honeybee breaks down the points in different files for each CPU and joins them back once the analysis is over.


@Mostapha I was using 4 CPUs, but I’ll double check and report back to you when I go back home!


@mostapha That was it, the number of CPUs, who could’ve known. As soon as I changed the number of CPUs to 1, everything worked perfectly. Also, it solved the problem of not creating .ill files, that I asked about in a separate question.

Thank you so much for your help!

hello! im having the exact same issue, how did you change the number of CPUs?


I’ve got the same issue but my number of points is negative (-3 by active CPU)
Do you know why ?


@madimas, I’m sorry for the delayed response. You can enter the number of CPUs using a panel and connect it to the runDaylightingAnalysis component. Please see the attached image.


Hi @Mathias, I’m not sure if I understand your question. Anyways, I was able to get over this problem by changing the number of CPUs to 1.
