Hi,

Can you make a screenshot of your material setup?

Oh I see, if you turn on the verbose toggle in the options settings and try to run the lightmapping again, it should say which material it is working with right before you get the error.

It seems from the error message that one of the color inputs is getting a number (float) / black&white input instead (the grey dot instead of a color vector (yellow dot))
