Corona Bump is so broken
dj_buckley:
Probably explains why my floors always look nice when I'm testing using 2d pan and zoom, nice matt look with visible grain, then when I zoom out to render, they look flat and shiny. Then I end up tweaking the shader so it looks right at normal resolution.
So in effect, we get it looking realistic, then we have to break the shader and make it unrealistic, just to make it look realistic again. Make it make sense . Sigh.
Be a good time for the devs to jump in. I'd hate to think all these speed increases we've been getting over the years are all at the sacrifice of something else.

I completely feel you.
Hard to believe the devs didn't know this was happening from the beginning. It's so disappointing.

There are many threads about this. Micro detail was discussed several times. I've never seen a good explanation from devs why this is so hard to do in corona.
Basshunter:
Yeah, I can see there's been couple of threads mentioning this problem in the past.
I Always knew something was wrong with my materials when looked from a distance but wasn't sure what is was until now. Man, you just get a completely different material when you zoom out! The only way to get a proper bump that still works in the distance is to set Blur to the lowest value possible. However, doing this would increase render time.
This is a big deal in my opinion! How is it that one of the best render engines for archviz can't just handle bump properly?!
dj_buckley:
Turns out I investigated this in 2019 - 3 whole years since I've been tweaking materials to combat this issue - https://forum.corona-renderer.com/index.php?topic=23230.0
