Someone knows how to fix it?

Hello everyone!

I have a problem with instanced static meshes in my blueprint class.
Only one wall has shadow and i don’t want it to have, I want it to be normal, like the other walls… I deselected the “cast shadows option” but it didn’t work I also added a Sky light but it did’nt work…

That’s not really a shadow, but more like a light feature. You can disable the light affecting this object by going to the material and set the shading model from Default Lit to Unlit, connect your color to the emissive input and you’re done.
