I added a HDRI as enviroment on cycles, but the model that i got here (an Eye) isnt reflecting good, at least, not a definite picture.

That's what i have:

But this is what i need:

Can someone help me with this? :( i'm a little lost on Cycles and materials..

    $\begingroup$ Isn't this a duplicate of you previous question? Also it looks like it is working, the only thing you have to change is your materials. $\endgroup$

  • $\begingroup$ Oh, no, on the previous question i was asking about the enviroment Hdri and the reflection, right now i'm only asking about the reflection, because it doesnt work for me, i also tried adding more samples, but is still the same. $\endgroup$

  • $\begingroup$ It is obviously reflecting something. The glossy has a very high roughness it looks like . . . could you upload a .blend? $\endgroup$

  • $\begingroup$ Ok, give me a second, even though its reflecting something the reflection look pretty blurry :/ give me a sec.. $\endgroup$

    $\begingroup$ Also check and make sure that you don't have another version of the eye over the one you are working on. That would do it. $\endgroup$

It looks like you need to turn down the roughness on the glossy shader. Roughness is how much the light scatters away from the perfect specular angle. It makes for blurrier, less crisp reflections.

Here is a diagram:

The first three examples on the left are a ray hitting glossy surfaces with varying roughness (left to right no roughness to high roughness), the fourth example is a ray hitting a diffuse surface for comparison.

  • $\begingroup$ The roughness of the glossy shader is 0.017, is pretty low already :/ $\endgroup$

  • $\begingroup$ Fixed it! i changed the roughness to 0 :D $\endgroup$

  • $\begingroup$ @VinceScalia Thanks! I made that diagram a while ago for fun when I was bored, I figured I would use it sooner or later. :D $\endgroup$
