Object with emission shows up in Viewport but not when rendered In an animation I did where the camera flys around a fishing shack, there is a ball in the sky with white emission that shows up on in the Viewport but doesn't when rendered. Initially I thought it had to do with a cube in front of a spot off to the side of the frame, put there to create a light stream, that blocks the view of the &quot;moon&quot;. But, when I turned it off, it still cannot be seen.    The camera has a view of 2000m, which I believe is sufficient. Interestingly, when I had Concierge Render crank out the whole film, this is what this frame looked like (before I made alterations to render settings.
Why does my object not show up? This is meant to solve this problem once and for all. What is every reason an object isn't showing up in a render or viewport in when using the cycles render engine?
How to vertically center content with variable height within a div? I have a High poly mesh and I have decided to make the low poly by merging as it is easiest for me. Would it be possible to change the W Hotkey , so that it merges to the center automatically? It is time consuming pressing W > Merge > Center. Toggle wireframe mode with hotkey How do I toggle in and out of wireframe mode with my keyboard? Is there a hotkey for this?  I'm a beginner (obviously). I thought I could find this in the "view" menu, but it either doesn't exist or I have horrendous eyesight. Thanks!

Remove application from Google Launcher Identifying and solving javax.el.PropertyNotFoundException: Target Unreachable After you get the Reindeer Stables, you can add decorations through a text form to increase production speed. I've added a few decorations myself, but I was wondering what all of them are. I know that some entries seem to be "synonyms". For example, if you enter "wreath" and then "garland", you'll only add the "a Christmas wreath" and trying to put up the garland will return "We already have a Christmas wreath".  These are the decorations I've already added along with discovered synonyms.

Comma usage with compound sentences {actually compound predicates as per Rob's answer} Rule 101 of compound sentences is that a coordinate conjunction must be accompanied by a comma most of the time when joining independent clauses, yet I stumble across sentences all that time that seem to abuse this rule. Normally, it's a case of the subject not being present in the second clause, as in the following example:      "They usually start out as an abbreviation, but turn into acronyms   when they become well known."   (taken from the Oxford Style Manual)   To me, this comma cannot be correct because the clause after the comma doesn't contain a subject and therefore cannot be independent (right?). As far as I'm concerned, it's not the 'Comma to set off a contrast rule because I can find plenty of other where 'and' is used and the subject's missing in the second clause.  what's the deal here?   Thanks in Advance for any responses I may receive! apt vs apt-get error code Strange thing I have here, when apt is locked by something. Respectively, the error codes don't match up. apt update seems to always return success 0, whereas apt-get update returns a proper error code.  vlastimil@vb-nb-mint ~/Development/bash $ sudo apt-get update Reading package lists...

Show that $\sup(A \cup B) = \max\{\sup A, \sup B\}$   Here's what I did so far:  Let $\sup A, \sup B$, and $\sup (A \cup B)$ denote upper bounds of $A,B$, and $A \cup B$, respectively. If $x \in A$, then $x \le \sup A$. If $x \in B$, then $x \le \sup B$. In either case, $x \in (A \cup B)$. So either $x \le \sup A$ or $x \le \sup B$. In either case, $x \le \max \{\sup A, \sup B\}$. So $\max \{\sup A, \sup B\}$ is the upper bound of $A \cup B$, which means $\sup (A \cup B) \le \max\{\sup A, \sup B\}$.  I do not know if there's a better way to go at it, but all I did was show the inequality. Can I do this, and show the reverse inequality? If so, how can I go about doing that?

Here is what the output of Disk Utility looks like:        As you can see on the first screenshot the disk has 120GB. However, the partition chart on the same screenshot only shows 70GB. Also the other two screenshots show that only 70GB out of 120GB seem to be available.  The command diskutil list shows that the physical disk0 is 120GB big, but the synthesized disk1 only 70GB:  /dev/disk0 (internal, physical):    #:                       TYPE NAME                    SIZE       IDENTIFIER    0:      GUID_partition_scheme                        *121.3 GB   disk0    1:                        EFI EFI                     209.7 MB   disk0s1    2:                 Apple_APFS Container disk1         70.0 GB    disk0s2  /dev/disk1 (synthesized):    #:                       TYPE NAME                    SIZE       IDENTIFIER    0:      APFS Container Scheme -                      +70.0 GB    disk1                                  Physical Store disk0s2    1:                APFS Volume Macintosh HD            60.2 GB    disk1s1    2:                APFS Volume Preboot                 21.7 MB    disk1s2    3:                APFS Volume Recovery                509.9 MB   disk1s3    4:                APFS Volume VM                      2.1 GB     disk1s4 When is it correct to use "yourself" and "myself" (versus "you" and "me")? When I see someone else being embarrassed / humiliated, for example a singer forgetting their words in a concert, I would say something like "I feel embarrassed for them". But is there a better word to describe this feeling?  I would say it's a mix of:   Empathetic discomfort for someone else's humiliation Tension; hope that spectators will be forgiving Frustration that I cannot help them   Other scenarios I would feel the same emotion:   Seeing someone make a presentation, the slides are all out of order, and their face gets red with embarrassment while there's a tense silence in the room. Seeing someone make an embarrassing social blunder in front of unforgiving people. Seeing a speaker who keeps making a distracting and annoying gesture, and they don't realize that the whole audience is annoyed. Seeing someone be taken advantage of, like seeing someone naively and happily accept a terrible offer on a car. Seeing a person of strong image (for example the CEO of your company) do something like accidentally leave their webcam on after a conference call, and employees see him/her let out a big burp and pick their nose or something.   In these cases it's important that the audience is not forgiving, even if they don't confront the person about it. The person may or may not know they are being humiliated.  "Pity" as proposed in an answer seems very close, but I think it lacks a few components. I think "pity" has a chronic connotation - that you are referring to the general state of things rather than a specific event.  I think "pity" also depends on the subject suffering, but in my example they are often oblivious.  It could very well be that there is no word for this at all.  NOTE: Some people do not feel the same way I do in this scenario, so you may not think this question makes any sense. I read a novel where several enemy alien species were stranded together on an interdicted planet.  They had to recycle everything and keep hidden. By "keep hidden" I mean make sure there is no evidence of their presence visible from space. They recycled everything and lived in camouflaged dwellings.  The younger generation was building a mixed culture community until the older home species showed up.  One of the alien races had a body made of rings or donuts of gases that mixed to express itself. Members of this species could be taken over and controlled by rings transferred from another member of the species.  The book may be 20 years old or more.

Is there a way to make it work together with sorting? Let's say I want to sort table by column &quot;length&quot; and get the order (sequence) of lines by length from shortest to longest. I know I can use some office spreadsheet software easily for this to sort by column and populate new column with order (sequence). But I would prefer to do the whole job in QGIS. As workaround there is also  - using mmqgis plugin and function modify/sort and after that use &quot;$rownum&quot; on the new saved file.
