Question by Kalu · Aug 30, 2011 at 04:09 PM · texturegetcomponent

Access the texture of a sub-object

I work on a project to (for simple) change the color of the walls of a house. For that I prepare a home (for now it is a cube) in which I separate the walls of the rest of the model (in 3DS Max) and I named this group of wall "Mur". In Unity, I have my house with the "under subject" => "Mur" but I can not access it to change its texture.

txtrLoader = Resources.Load("Texture/texture", typeof(Texture2D)) as Texture2D;

Component sousObject = GetComponent("Mur") as Component;

//sousObject.renderer.material.mainTexture = txtrLoader;

//sousObject.renderer.material.SetTexture("_MainTex",txtrLoader);

here are the two things I try for now (in comment) and the error is : "NullReferenceException: Object reference not set to an instance of an object".

The error is on the fact that he can not access the targeted sub-object.

txtrLoader = Resources.Load("Texture/texture", typeof(Texture2D)) as Texture2D;

Transform sousObject = curModel.transform.FindChild("Mur");

sousObject.renderer.material.mainTexture = txtrLoader;

I managed to find the right way, with these three lines, I target the "Mur" and I replace its texture.

Loadable resources need to be in or under a folder called Resources within Assets
