texture problem - like jpg compression

Hi,

in one scene have this weird texture problem like jpg compression - square blotches. Never saw this before and texture has very good quality, no errors in PS. What is wrong?

I have no idea what’s going on here, can you send us the texture and the scene for investigation?

Scene sent. Thank you.

Thanks, we’ll have a look at it and will get back to you afterwards.

Thank you.

Texture is indeed with a very good quality but the Camera is zoomed way too much.
The image resolution is 4500x6000 but the camera only see a fraction of that image and the final resolution is 6000x4500, that’s why the image looks bad.
You will need about 4times higher image resolution or order to get render output with the same image quality.

I’ll send you the math work via email since I’ll use some information from the scene.

Ok, thank you.
