I really thought I got this but I can't seem to get this material right. I'm trying to achieve this:     In case, anyone wants to see more photos of this, it's the Dior foundation cap. But I cant seem to get it to shine like this. Although I've tried various nodes, this is what I'm doing currently:  And this is what I'm getting:  My roughness for the above image is at 0.192 and reducing it further isn't looking great. I've also tried using principal BSDF with metallic at 1 but that didn't look similar to what I want either. This is the HDRI I'm using:  Any tips on how to come closer to the reference images would be really appreciated! Edit for Jachym:
I am trying to render a kitchen sink / Faucet    Here is another reference image of what I want   What I have got so far is this   Settings for World:  I have used an environment map HDRI with 0 saturation.  Material settings:  Triad with glossy, glass anisotropic and there mix shader combinations and the new principled bsdf shader too but didn't get the required result.  Studio lights: Followed multiple youtube tutorials on setting up studio lights in blender but the results were not what I wanted.    LEAVING CYCLES :  Decided to try some other software So, Downloaded Keyshot 5 but keyshot wasn't able to produce cycles like results LoL.  Not : I have always struggled to get professional quality product rendering in cycles      So now I'm back in cycles looking for help.
I am considering buying a Dell XPS 15 laptop. The laptop has a Nvidia 420m card which should work with Linux but I keep reading that the Nvidia Optimus technology isn't supported on Linux. I am not really interested in switching from Nvidia to Intel to save power but need to know that the Nvidia card will in fact work if I installed Ubuntu.  If anyone has experience using a Nvidia card with Optimus technology or even better the exact laptop in question (Dell XPS 15 with 1GB NVIDIA® GeForce®  GT 420M) it would be great.  A major problem holding people back from adopting Linux is this sort of hardware issue. I am a long term Ubuntu user and supporter who can't afford to make a mistake with a purchase like this. I don't want to spend £500+ to find I have no graphics acceleration because Windows 7 is not an option. How to tell Google to ignore URL parameters and forget about any already crawled? Why does Python code use len() function instead of a length method? I know that python has a len() function that is used to determine the size of a string, but I was wondering why it's not a method of the string object.  Update  Ok, I realized I was embarrassingly mistaken. __len__() is actually a method of a string object. It just seems weird to see object oriented code in Python using the len function on string objects. Furthermore, it's also weird to see __len__ as the name instead of just len. How to force Windows to rename a file with a special character? I have a song that Windows can't play because there is a question mark in the name of the file.  "Where Have All the Cowboys Gone?.ogg" // as an example   So I try to rename it and Windows complains whether I try it in Explorer or from command prompt.  Error I get when trying to copy, rename, or move is:     The Filename, directory name, or volume label syntax is incorrect   Is there a Windows way to force a rename in this case?   Update  I'll keep an eye on this question, but after 13 answers and many attempts (aside form 3rd party solutions) it seems that Windows can't do this (or at least my windows can't, no short names). So I'm accepting the answer which was my original solution anyway of using Linux. It would be nice to see Windows handle this somehow, so don't stop just because I've accepted this answer, the question still stands! jQuery scrolltop firefox not working Avoiding jumping frames in beamer Logic soundness and completeness I have to do a number of similar type questions, but I am having trouble grasping the general concepts around soundness and completeness.

Changing the resistor to be in front or behind an LED doesn't affect brightness? Note: I am very new to the more advanced side of electricity. I do not have a firm grasp on the exact mechanics.  Lets say I have an example circuit:  5V Power Supply -&gt; LED -&gt; Resistor -&gt; Ground  Now the LED is receiving 20ma and 5V. If I were to switch the LED and the resistor however, the LED should receive less voltage but the same current, so wouldn't it be dimmer? Or would it receive the same voltage?

How do I join two separate objects so I can edit them as one mesh? I've created main SELECT statement like below.

(the rule of inference) The following is a homework problem:  Prove that between two roots of the function $f(x) = \exp(x) \sin(x) -1$ there must be at least one root of the function $\exp(x)\cos(x) +1$.  I think it is possible to prove it by simply computing the signs of the functions at $\frac{\pi}{2}k, \pi k, \frac{3\pi}{2}k, 2\pi k$. However, I'm looking for a more elegant way. It is intuitively clear that the roots of $f$ are ˋˋconverging'' to the roots of $sin$ and the ones of $g$ to the ones of $cos$. Do you have any hint how to construct a nice argument based on this observation? ls: cannot access .gvfs: Permission denied
