So I have this problem, I have 7 or 8 "screens" in my scene, to achieve certain effect, they have to share the same uv map that contains all the screens content, the camera starts in a close up position then pull away to a wide shot, in order to keep the screen sharp when it's in a close up position, I created the image sequence in 9216*9216 resolution.
It's fine when the camera is up close, sharp, bright, all works out, but as the camera pulled away, the render result gets blurry, the image gets dark, the model's screen gets dark,(*I was planing on increase the emission value as the camera pulls away to fix this "gets dark" issue. you might know a better way or why this problem occur, be great if anyone could help). the result is showed blow. to compare with what it should be look like, i scale down the same source image on the right hand side.
As you can surely see, it gets blurry.
I don't have depth of field enable in my camera just to be clear, I use arnold 5.0.2 in maya. I use after effect to create the image sequence, and it's all created properly, no one single image gets scale up and lose resolution.
Is arnold down sizing my texture?
