Tensor value seems change after call ToRenderTexture（Inconsistent with RenderTexture） #287

Hi， everyone~

Here is how I call ToRenderTexture， image

and the function RenderTextureToTexture2DRFloat implements as below， image

The Result I get like this， image

You can see that colors[0].r (0.02085956) is not equal to workerOutput[0,0,0,0] (4.453816) My question is, shouldn't the two be equal？ or am I missing something？ Thank you for your reply

Seems like it is normalized. Literally RenderTexure is for displaying an image (color or gray matrix of values between 0 and 1) on your monitor. It is not for some arbitrary matrix or tensor of any values like 4.453816. Check the function ToRenderTexture().
