Why does the light leak like this? There is Only Sunlight on the map. but light is leaking from this corner? moreover there is no error in Modeling. i checked everything everything is normal. i tried with different materials the problem still persists.
Try using light blocking boxes around the problem area, at least 20 cm thick if possible.
I can’t find that
You cant find a box? And stretch it to size?
Even then, the leak is because your geometry is non manifold. That’s all there is to it.
But, same problem with the model is coming from REVIT via direct link. No such problem when rendering in REVIT, or in Blender via Speckles, or using a farm for REVIT rendering files.
