I am using gameobjects as trees for various reasons. Is there a way I can create billboards like in the terrain tree system? Do I have to write a shader, or can I write a script instead? They don’t have to fade smoothly or anything I just need the billboards.
Simply use a quad (not a plane).
Create a new Material and drop on it your Texture.
Make sure that you use .png textures that have transparency.
Pick the “Particles/Alpha Blended” Shader.
Adding the Material on the Quad will show the effect needed.
Now to make the quad a billboard, write a script and drop it on the Quad.
This script should have a transform.LookAt() (check the documentation) in the Update.
