PIC Terrain Creator
The PIC Terrian Creator is an effective tool for creating visual landscapes of your games. It is available in two options – the Athena Terrain and Danae Environment.
The first one has customizable height maps and textures. You can generate the terrain on the editor, so there’s no need to upload complex maps with large file sizes.
The second one contains a lot of physics options to make your scenes dynamic. You can paint your sceneries and add decals on top of objects. This can be useful for creating natural scenes.
