I have made an island on blender but since I always have collision issues, I convert the island to a whole bunch of wedges by a plugin. It works great! But, the problem is. You have to colour EVERY SINGLE TRI (Sorry If I spelt that wrong). So, the island looks really ‘harsh-coloured’, It’s not smooth at all. Is there anyways where I can fix this so I can blend colours and make the colours more vibrant please?
What you could do is color it in blender. There is not really a paint tool or plugin as far as i know.
You could also try to mess around with textures and/or decals.
I don’t really understand though why you made it all wedges…
