Hi there.
Below is a link to my screen recording:

I've noticed a strange situation. When I increase render resolution refracted materials look different. More dark and more blurred...
Corona render settings are the same. Latest Corona version.
Thanks.

It'd be easier to compare if you could post the two images, then we can overlay them or put them into a comparerer :)

I think it is very visible.
I've posted video to show that I didn't touch any setings...just cranked up the res.
Comparison picture attached.
Thanks.

Hi there, are you able to share your scene with us via our private uploader? If so, the link for it is in my signature below. Thanks :)

Switched back to RC2 - the same.
Now I've found the problem - it's bumpmaping.
But I don't know why.

Sure. I will do this a little bit later.

While it was very visible, it's just easier to see WHAT is different from the images. Videos are helpful when there's an involved workflow so we can see the steps, but in simple workflow cases, the images are better (well, the scene is best of all :) ). TY for posting the comparison image, and the extra info about it being bump!

It's probably because of filtering. Most renderers are very sensitive about bump map filtering type and strength. The only solution to this issue, is to adjust material at final resolution and if you'll want to change resolution, you will need to re-adjust material again... or render it at highest resolution and downscale in post.
