Stronger bump goin' to weaker bump...Why? Advice please...

[Fibonacci]

Hey,

I got something interesting result in the raw render.

Anbody has any idea what and how I have to change in the render setup or in the mats?

I'd wrote all info on the pic.

Thanks any comments !

I suppose it's because of filtering. You can disable it from Corona's ui or change value in material settings.

Thanks Maru,

I'll try it, but the bump is pretty low, only 0,065 and pyramidal filtering...

do you have an image of the map? the bump amount can also depend on how much contrast is in the map. your bump looks to strong if you ask me. less is more on woods like this.

All woods have an 0,065 setting in bump. For me looks like the bump goin' stronger and stronger of the center.

Anyway...

Try to lower filtering bluring, as maru suggested already. And 0.065 may be still too strong - corona is quite sensitive for low bump values, atleast in A5.

I compared results and 1 in Corona A5 is as strong as 65~ in Vray

So your 0,065 is still 4,5~

I often have the same situation where I have some elements rendered fast and they look smooth but then I get some objects with noise.

Is it possible to add something like "Focus Render Power on the selected area" In real time? Sometimes I even cancel render to rerender just a region but it would be great to have a progressive focus ability.
