HI
You just have to adjust the fog, the settings between 2.3 and 2.4 can change, this also happens with the illumizazione given to the light material.
And only one setting problem, courage you must be enterprising, the program does not bite.
I hope that is the problem. Or turn off the fog option.

Hi Riccardo! Thanks for your response, I found the problem, the fog is off, the emissive materials are fine, but there was some particle system out of scale, was too big and out of the model!!!
