Changes to Texture2D persist after I stop playing
I'm modifying a Texture2D with SetPixel(), but when I stop playing my game the changes are still present in the scene view and the next time I play my game. I have to close Unity and restart it to have my texture reset to its original state.
How can I have my Texture2D reset when I stop playing my game without restarting Unity?
Before you manipulate your texture, make a copy:
var tex : Texture2D = Instantiate(renderer.material.mainTexture) as Texture2D;
renderer.material.mainTexture = tex;
That worked perfectly. Thanks :) I'm surprised that unity acts like this to begin with.
Textured are stored on the GPU. The local copy is apparently being garbage collected when there is no longer a reference to it. I agree that this should be avoided by the editor without extra coding requirements.
I ran across this using a non-main texture, and solved with the following (in case anyone comes searching for this, like I did)
originalTex = my$$anonymous$$aterial.GetTexture ("_CustomTex");
...
void OnDisable() { my$$anonymous$$aterial.SetTexture("_CustomTex", originalTex); }
