I, hopefully, have a simple question.
I have a model with a window (which is just a hole) with a arch shape at the top. But the arch shape is not detailed enough, meaning that it consists of too few polygons. So, as you can imagine, if a do lighting on the window, it is not very nice or detailed because of the low number of polygons. Cant a select the polygons in the arch and make the area more detailed (enlarge the number of polygons in that area)?
