GI Not Baking In 5.7.1 Using CPU Lightmass

hello, i am trying to build light using CPU lightmass in 5.7.1 . but , GI is Not baking only Direct light is baking no indirect light . I enable most setting required for baking. also tried in different project because thought maybe project got corrupted still same result in different project . I did baking in 5.6.1 with same setting and its working. I have Attached all relevant screenshots.

baked this in 5.6 GI is Working as intended

try stock lightmass settings. it seems to have some issues with (mirror) planes for some reason, but replaced with some volumetric geometry it properly blocks and propagates light into tight corners. this is a look thru a wall.

hello to the forum, btw. : )

@glitchered Hello, i hope you are alright and thank you for your advice. I tried baking with stock setting still no GI. As for geometry i am using SM_Template_Map_Floor which has decent thickness but still not baking. I also checked if maybe it doesn’t have proper UV channel for baking light .but, it has. Also checked light map density which is green.

build with stock setting.

again thanks for reply.
