Hi everyone,
I have tried them all!
The only way to fill this hole in the scattering is by removing a large amount of polygons from the surface.
It is not related to the slope option, I checked.
There are no exclude/include.
And Why right there though? It is always there. Even if I clone the surface and I make some editing on it.
I don't understand.
I attached two images, in the second one the render is on orto mode from top to show the entire "alopecia" spot.
Thank you!
