I’m trying to dynamically load a sprite atlas from the Resources directory which is used in the material of MeshRenderer on multiple objects. All of the objects with this material & texture are in a prefab.
Is there any way to change the texture of the material once and have all objects update at runtime, while at the same time not affecting my project settings?
Let’s say I have a new Texture2D object in new_tex. if I do:
gameObject.renderer.materials.mainTexture = new_tex;
Then an instance of the material is created for that single gameObject. I will have to have my texture updating script go through each object that needs this new texture, set the material’s mainTexture property, and create a new material instance in the process. Heck, even READING from materials creates an instance (dumb dumb dumb).
Or I could do:
gameObject.renderer.sharedMaterials.mainTexture = new_tex;
which switches the textures of all of the objects at once, but also saves these changes in the prefabs! Why in the world would I want to change a prefab during runtime?
Any suggestions for how to dynamically load textures while not mucking with projects settings as an unwanted side-effect?
