Unity : How to convert Texture2d into Render Texture (RenderTexture) ?

ConvertTextrure2dIntoRenderTexture.cs

private static void ConveretTexture2dIntoRenderTexture(out RenderTexture out_renderTexture, in Texture2D input_texture2d, int resolution)
        {
            //int resolution = 1024 * 4;
            // texRef is your Texture2D
            // You can also reduice your texture 2D that way
            out_renderTexture = new RenderTexture(resolution, resolution, 0);
            out_renderTexture.enableRandomWrite = true;
            RenderTexture.active = out_renderTexture;
            // Copy your texture ref to the render texture
            Graphics.Blit(input_texture2d, out_renderTexture);

            // Now you can read it back to a Texture2D if you care
            /*
            if (inputT == null)
                inputT = new Texture2D(inputTex.width, inputTex.height, TextureFormat.RGBA32, true);
            inputT.ReadPixels(new Rect(0, 0, inputTex.width, inputTex.height), 0, 0, false);
            */

        }
