Dome light reflections working differently in 4.31?

[tmbarker531]

For exterior scenes, we often use a two hdri dome light solution to control diffuse lighting and reflections separately. One light will only have diffuse + specular checked and the other will only have reflection checked. We've noticed that in the 3.1 update scenes with reflection only dome lights don't pick up any reflections. Attached are two images of the same scene, one rendered in 4.3 and one rendered in 4.31. There is a dome light set to blue with only reflections checked and one dome light set to red with diffuse and specular checked. In the 4.31 version no blue is reflected.

There is a description in the announcement for 4.31. Take a look at the attached images in this post by the developers: https://forums.chaosgroup.com/forum/...nload-next-3-1
