I need to draw a few molecular hybrid orbitals and I'm going to use chemmacros.

I've been reading about compatibility issues existing with this package, but I cannot get it loaded in anyway.

Using the chemmacros documentation examples:

This is the MWE



   overlay ,
   opacity = .75 ,
   p/scale = 1.6 ,
   s/color = blue!50 ,
   s/scale = 1.6


When compile this I get this output log:

    Please put the errors in textual form and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document} – albert Dec 3 '18 at 12:10
  • I hope the changes will help you to reproduce my issue. – JFernan Dec 3 '18 at 12:22

    Indeed it would be better to include the code as text, then somebody who wants to answer does not have to re-type everything. Luckily this example is taken from the chemmacros manual, which allows to copy-paste the code. You can probably solve the issue by putting \chemsetup{modules=orbital} before \begin{document}. – Marijn Dec 3 '18 at 12:28
  • Thank you, @Marijn, that was the solution, where is this specified in the chemmacros docu? – JFernan Dec 3 '18 at 12:30
  • This is described in Section 3.1 of the manual, however the manual is not very clear about this so it is completely understandable that you missed it. – Marijn Dec 3 '18 at 12:31

I completely missed out the 3.1 section in the chemmacros docu. So adding


in the preamble, the problem fixes. Like this picture shows enter image description here
