Question about accessing RenderTexture with RenderTextureFormat.RGFloat

Unity Engine
1

Hi
I would like to get the pixel info for a render texture with RenderTextureFormat.RGFloat. I used the following method:

myTexture = new Texture2D(renderTexture.width,renderTexture.height, TextureFormat.RGB24, false);
RenderTexture.active = renderTexture;
myTexture.ReadPixels(myRect, 0, 0);
myTexture.Apply();

but myTexture came out empty. What shall I do? Thanks for the help!

you should post the entire code. fe where the rect is defined, the render texture is filled and the texture is displayed/saved. you know that rendertexture is pro-only feature and you own a pro-licence?
