Warning: Consistent lighting elements are not supported with irradiance map and will be disabled.

When I replace Brute force, with Irradiant map, the render is done correctly but, in the log, I get a waning message that I don't know if it's normal or if it can be fixed. But how.? Maybe it's nothing serious. The message is
"Warning: Consistent lighting elements are not supported with irradiance map and will be disabled."

It's normal. Read the yellow paragraph at the bottom to understand what the consistent lighting elements option does.

ok. But now in irradiance map mode it is slower than Brute force. Also in the version for 3dsmax there are options in Global Swich that solve this alarm. Why don't they exist in the Sketchup version?

Different integrations of V-Ray.

so what is the solution? in previous versions there was no such problem and the performance differences were noticeable. I currently have ver 5.20.04.

V-Ray 5 is a different beast than the preceding ones.
If you absolutely need the IRMap, it's best if you go back to V. 4.
