Remove the black spots of Mesh

Questions

Hello,
InkedImage 2_LI

I’ve created some meshes like the image above.

And I’m wondering that is there any way can remove the black spots?
(I used the HemisphereucLgiht, and used “mesh.diffuseColor = vector3()” )

Thanks.

You can add another light. If your first hemispheric light has a (0,1,0) direction, the second one can be (0,-1,0).

Hi Evgeni,

I’ve tried the method you provided adding the other light. And it works!!!
Thank you so much.
