RenderTexture to Texture2D
mornin' guys,
I'm searching a solution to save a render texture to a texture 2d with alpha and then save it to file. After some researches I found some similar questions like https://answers.unity.com/questions/9969/convert-a-rendertexture-to-a-texture2d.html or like https://stackoverflow.com/questions/44264468/convert-rendertexture-to-texture2d but this doesn't work good: the resulting texture 2d is darker than render texture. Anyone have idea about it? Maybe I'm missing something.
This is my method for conversion after reading the other solutions.
public static Texture2D ToTexture2D(this RenderTexture renderTexture)
{
Texture2D tex2D = new Texture2D(renderTexture.width, renderTexture.height, TextureFormat.ARGB32, false);
RenderTexture active = RenderTexture.active;
RenderTexture.active = renderTexture;
tex2D.ReadPixels(new Rect(0, 0, renderTexture.width, renderTexture.height), 0, 0);
tex2D.Apply();
RenderTexture.active = active;
return tex2D;
}
