[Solved] Refraction Problem C4

[aref3dsmax]

Hi. My corona is not work correct

The black thing in your image - what are you intending it to be in the end? Water?
I think it has flipped normals. Can you try applying "normal" modifier to it?
Corona 4 is more sensitive to normal direction than the older versions. If you are creating something refractive or volumetric, make sure that:
- it is a solid object with some thickness (for example: a box instead of a plane, a sphere instead of a circle, etc.)
- the normal directions are correct

The easiest way to check normals direction is to select your offending object, right click > object properties > enable backface culling. If the normals are correct - the object will appear shaded in the viewport. If the normals are flipped, it will be invisible (fully transparent).

Hope that helps!

hi again. yes normal is correct .
when create normal modify the water is not black but not correct reflection refraction

I see that you have Reflection Level set to 0 (disabled) on the water shader. It should be at 1 if you want to see reflections on that material.

i want refraction . reflection have not problem. my problem with refraction.

i test with a simple scene But the problem remains
Do we need thickness in corona for water levels?

[aref3dsmax]

please see the picture. i work with vray. just convert from corona and everything is correct

[aref3dsmax]

sorry! i find my problem!

my floor shader is Ray switch and reflection and refraction was black!!!

because in corona, we have just one way to control saturation
