Strange lightmap rendering

I’m trying to export a unity scene to babylon with unity export toolkit. it does fantastic job but I have very weird lightmap rendering, at least not what i wanted. Do i miss something?
btw, I have only one ambient light.

amLight = scene.getNodeByName("Ambient Light");
amLight.diffuse = amLight.groundColor = new B.Color3(1, 1, 1);

Welcome aboard!

Pinging @MackeyK24 who is the master of Unity exporter!

It the lightmap textures… The new version of the toolkit fixes this issue :slight_smile:
Will be out soon… When Babylon 4.2 releases

very good. thanks for the efforts. Btw, i solved it by changing the exposure of the exr file and then exporting to png.
