I'm rendering a few scenes with command line and it works fine with most of them. But there is one scene where I get the following error: "cannot render, no camera". I can manually render it because there is indeed a camera in the scene.  I erased everything that could cause trouble ending up with only a cube and a camera. And all properties match with the working scenes but it's still not working with this file.
I just started blender and one of the main things you have to do is to render to make an animation, but I can't seem to do that. Whenever I click Render and then render image or render animation, at the top of the screen it says 'No camera found in Scene "Scene". I don't know why this is happening.
Tall curly brace I would like to put a tall (long) left curly bracket on the left side of the following:  \documentclass[12pt]{article}  \begin{document}  \noindent c: $\{$1, ..., n$\}$ $\rightarrow$ $\{$1, ..., n$\}$, such that  \hspace{20 mm}  \noindent c($a_i$) = $a_{i+1}$ for 1 $\le$ $i$ &lt; $l$  \hspace{20 mm}  \noindent c($a_l$) = $a_1$   \end{document}   Please let me know if you can help. Thanks! I have a range and need to sum it using SUM function but the result is N/A if there is any N/A value. How can I make the SUM function to treat the N/A value as 0 value?  Please help! Deriving Chinese Remainder Theorem from gcd Bezout identity Without recasting and in lieu of unsightly suspensive hyphenation, could these work?

My standard document preamble includes the "usual suspects" for non-English speakers (, , ) and a bunch of other packages. Assuming I were to convert to XeLaTeX, what modifications of my preamble are advisable? I'm aware that the expansion=true option of the  package is not (yet) available for XeLaTeX, and that  is sort of a default package for OpenType fonts. What other packages (and package options) should be removed and, vice versa, incorporated when switching from pdfLaTeX to XeLaTeX?

Prologue:  This is an effort to follow up on  which is marked as a duplicate of  highly voted and status-declined feature request (although they seem to be different, one focusing on the OP and the other on the downvoter).   My New Year's resolution was to downvote more.  So on January 3rd or so, I saw a post that was low quality, and downvoted.  Two days later, I came back to see if it was ready to be deleted or had gotten piled with downvotes, to find it with a significant positive score!  At which point, I noticed that the answer had been significantly improved.  So I retracted my downvote, changed it to an upvote, and immediately resumed my dearth of downvoting again.  I think I have a responsibility to downvote bad posts, despite that oh-so-painful -1 rep penalty.  But if I am also going to have the responsibility to follow up on every downvote I cast, I'm not going to bother. I don't want my downvote to leave a residual penalty on posts that were once low quality, and I am not going to trouble myself to keep checking up on every post I downvoted.  Can a downvoter have an option to be notified when a post they voted down was edited?  I wouldn't make this an automatic thing, because not all downvoters want it, and it isn't applicable to all cases of downvoting (although  that this should be part of the responsibility of a downvoter).  Personally, I would make this a universal toggle on-off option on the user profile page, not a question-by-question option, but I don't have strong feelings about it. With the announcement of the detection of gravitational waves, questions about the implications proliferate.  Some relate to the possible existence of gravitons.  The analogous relationship between gravitons/gravitational waves and photons/electromagnetic waves is frequently mentioned.  The detection of individual photons required experiments of very low intensity light, yet their existence was inferred (prior to their actual detection) by Planck and Einstein (among others) using the properties of experimental black body radiation and the photo-electric effect.  If the prospects for detection of gravitons requires similar study of very low intensity gravitational waves, then those prospects are very dim indeed. My question: are there similar indirect "experimental" methods for inferring the existence of gravitons? How do I display 2 sections side-by-side? Add additional sub-groups to the new Badge page & related Feedback On the  (A+), there are sub-groups under the major groups.  For example, the Participation Badges group has related badges Commentator and Pundit sub-grouped, and Quorum and Convention sub-grouped.  I am of the opinion at least 1 of the following additional sub-groupings should be made:  Question Group   Student &amp; Scholar Investor &amp; Altruist Promoter &amp; Benefactor   Alternately, one sub-group of Investor, Altruist, Promoter &amp; Benefactor    Answer Group   Teacher, Enlightened, Guru Consider moving Generalist to Tag Badges Group or the bottom of the Answer Group if Tag Badges is moved immediately below Answer Group.   Participation Group   Talkative &amp; Outspoken Caucus &amp; Constituent Precognitive &amp; Beta   Tag Badges  Move this group to either the bottom of all groups or below the Answer Group. Its current placement here creates a weird artificial barrier, especially with users who have no Tag Badges.  Moderation Group   Informed &amp; Analytical Taxonomist &amp; Synonymizer Critic &amp; Supporter Disciplined &amp; Peer Pressure Suffrage, Vox Populi &amp; Civic Duty   Alternately, one sub-group of Critic, Supporter, Suffrage, Vox Populi &amp; Civic Duty  add Cleanup and Organizer to the Editor sub-group add Citizen Patrol to the Deputy sub-group   NOTE: Since this is now status-completed, but only a select portion was completed, the rest of the request has been broken into 2 additional questions: Using InDesign CS6, how can I simultaneously edit A4 and A5 versions of a poster? I'm on Adobe Creative Cloud, so I have the latest InDesign, and I'm attempting to design a poster for my choir's next concert. Traditionally, I've done this in Photoshop, in two separate files, however I've recently started using InDesign after converting to it to create wedding albums through Blurb.  I've created an A4 document, and created an alternate-layout for it in A5. I've then lined them up side-by-side, and I've added a black frame to the A4 page, to act as the black background for my page (by the way, feel free to advise on better ways to do this).  My assumption is that I've failed to understand how this works, as I was hoping that I'd magically get a black frame on the A5 version, and that I could use liquid layout to get this to automatically scale (along with all other elements), in order to create the two versions simultaneously.  All help/advice would be greatly appreciated! How do you add a thin outline? I am new at this. I am extracting files a game. In the game they have thin black outlines, but they aren't part of a model. I am having trouble finding anything about this. What is the simplest way to do this?  Update: I think I am looking for something like freestyle. What is the simplest way to use this to create a thin black outline around a model? Using one group separator for integer part and another for decimal part (siunitx) I thought I was able to do something like this before, but I can't find my solution.  I would like to format my large numbers as follows:   12,504.3124 2359 3   I know I can use siunitx to partially set this up, but I'm not getting the results I want:  \documentclass{article} \usepackage{siunitx}  \newcommand\aenumA[1][4]{%%   \num[group-separator={,},        group-digits=integer,        ]}  \newcommand\aenumB[1][4]{%%   \num[group-digits=decimal,        ]}  \pagestyle{empty} \begin{document}    \aenumA{12504.312423593}    \aenumB{12504.312423593}  \end{document}   I would like a hybrid solution (commas in the integer part and spaces in the decimal).  I would actually also like to be able to group differently between the two: every three digits in the integer part, every four digits in the decimal part.  Is there a straight-forward way to do this with siunitx?  Or, do I need to split the number at the decimal and treat the two parts separately and then glue them back together? How do I find out which repository a package comes from? Is there a method or command which can tell from which repository a package is coming from? Suppose we view fluids classically, i.e., as a collection of molecules (with some finite size) interacting via e&amp;m and gravitational forces. Presumably we model fluids as continuous objects that satisfy some differential equation. What mathematical result says that modeling fluids as continuous objects can accurately predict the discrete behavior of the particles? I don't know anything about fluid mechanics, so my initial assumption may in itself be wrong. Pipe sound output to file?
