Daylight Simulation/ Mesh info is in numbers

Hello everyone!

I’m having an issue with the daylight simulation, at the last step to visualize it tells me that the output of the mesh was converted to numbers.
Does someone have any idea why this could happen?

I appreciate any suggestions, thanks in advance!

Update.

It was because I didn’t connect the actual mesh output from before the simulation.
But now results are in shades of black, does anyone knows why is this occuring?
