Hello! I'm very new to 3D in general and have a question on the best way to set up my project. I'm pretty sure the answer to this is very easy but I want to make sure I'm on the right track.
I'm doing the typical spinning earth dealio. I've setup my scene and added a sphere and given it a nice earth texture with a a bitmap material. All is good so far. Next, my goal is to add small circle buttons over certain cities on the earth. The user will eventually be able to click on the circles to interact with it. I'm basically trying to figure out the best way to add the circle buttons to the 3d environment. I initially tried adding the circles to an interactive movieclip material. That seemed to work, but the circles visually looked kind of crappy/distorted as the earth turns (since the earth sphere has a relatively low polygon count). So I thought maybe it would look better to not do an interactive movieclip material, but instead just add the circles as Sprite2d objects. This way the circles will always look at the camera and won't have the distortion issue. Check out this rough example that I put together: http://www.deathbychihuahua.com/earth/ You can see as the black Sprite2d object rotates around, the earth starts to clip it at times. I know I could just make the black square sit further away from the earth to fix this, but then it doesn't look like it's anchored to the city's physical location on the earth. What's the best way to fix this? Is there a way to force my 2d objects to render on top if they're in the same scene as the earth? Do I setup a second scene all together so I don't have to worry about the clipping issues? Any advice is much appreciated! Thanks, -Ryan
