Backed Indirect Color BLEEDS. Look the 6# post!

Please help me! The objects are separate, they have indetical materials, but different normal map. But it gets that purpish color after light build, that green color object used to be same bad, but somehow repared after thousands of building in different conditions. I dont’t know what to do(

Thats not it(

OMG You wer right! Thank you! But I dont understand how it bleeds SO FAR even behind the corner!? And also only on the wall…The first image stairs is dinamic and the walls are grey, but the second the bad result I asked about.

I set blue material’s diffuse boost to 0.1 and got this. I don’t think thats normal… Any sugestions, please? Looks like completely broken GI.
