I’m using Blender to make virtual flights around and over 3D-models that are made with Agisoft Photoscan Pro. The photos are taken with an airborne camera. In some cases the places I fly over is surrounded by water or has a streams/rivers flowing across.
Agisoft Photoscan Pro give me a lot of jagged surface where there´s water, often the water stands taller than the ground when I look at the 3D-model with Blender.
How can I select larger areas of water and then lower the Z-point of the high rised vertices out in the water?
