I wasn't sure whether to post this on the game dev Stack Exchange or the Blender Stack Exchange, so I'm just posting it here. Anyways, as you can see below MOST of my materials turn white when importing into UE4, however they still keep the texture, just not the color. How do I fix this? Thanks! :)
I used node textures in a mesh I exported to .FBX.  I then imported it into Unreal Engine 4 and it didn't import any textures; I clicked the Upload Textures option in Unreal Engine.  Is there something I'm doing wrong or is it Blender?
AutoHotKey: Calling one script from another script I need a DSLR camera with a barcode scanner for on-site tours photography, which means it needs to be untethered! The image would have to contain the barcode scanned information in the image metadata or in the name itself.  I've seen solutions like, Foolography and a $2600 Canon Studio Edition launched in 2010. But I'm not sure of either those products!  So I'm asking the gurus here how I can get this working, which camera would I need and any accessory necessary?  I'm trying to recreate something like I saw the on-site volume photographers do in Disney's parks. There is a formal definition for the Big O notation in . Up to now I have come across Big O in Numerical Analysis, Calculus and Algorithms which all are pretty distinct fields. What I am wondering is if that definition is global and is the only one that is used in every field where the Big O is involved or there are other ways that the Big O is defined in other areas  of Mathematics. vertical lines in matrix using tikz package my problem is interconnected to my two previous posts ( and) and i've tried to incorporate answers into solution but without success.   My task is this matrix multiplication with added description:   and my so far code follows:  \documentclass{article} \usepackage{tikz,amsmath}  \begin{document} \begin{tikzpicture} \node[minimum height=0cm,minimum width=2cm] (m) {}; \path[shade,draw] (0,2) -- (0,5) -- (3,5) -- (3,0); \draw (0,0) --(0,5); \draw (3,0) --(0,2); \draw (3,0) --(3,5); \node (r11) at ([xshift=0.6cm,yshift=4cm]m.south) {$S_{11}$}; \node (r11) at ([xshift=2.5cm,yshift=4cm]m.south) {$S_{12}$}; \node (r11) at ([xshift=2.5cm,yshift=2.15cm]m.south) {$S_{22}$}; \node (r11) at ([xshift=0.6cm,yshift=2.15cm]m.south) {$S_{21}$}; \node (r11) at ([xshift=0.6cm,yshift=2.6cm]m.south) {$--------------$}; \node (r11) at ([xshift=0.6cm,yshift=1.5cm]m.south) {$--------------$}; \end{tikzpicture} \[ \begin{bmatrix} \begin{equation}        wn_{1}           \\[0.3em]        wn_{2}       \end{bmatrix}  \]  \end{document}       with following output:      I am not able to add vertical line and nodes and incorporate the matrix into document (vector that follows behind the matrix is not centered). Problem with nodes and incorporation is the same as in . Do comic characters sometimes get drawn like the actor playing them? I noticed in Spider-Man's recent cameo in Captain Marvel, he appeared an awful lot like Andrew Garfield who is playing Spider-Man in the recent movie.    Irrelevant of whether it is just my imagination, do some depictions of comic characters morph to be more like an actor who plays them around the time a corresponding movie is released?  By comparison, here is Spider-Man's depiction in the Spider-Men crossover: Something small goes wrong, and this triggers something slightly bigger, which triggers something slightly bigger, and so on and so forth until you end up with a chain of problems of increasing severity until it ends in catastrophy.  Something like the old saying "for want of a nail the battle was lost", only highlighting that each intermediate issue was a problem in its own right, not just a stepping-stone to the final disaster.  Is there a common word/phrase that specifically describes this? I'm thinking "cascade of ever-increasing problems", but this seems clumsy, and I suspect there might already be a neat word or expression that covers it. Properties of $x_k=\frac{a_{k+1}-a_{k}}{a_{k+1}}$ where $\{a_n\}$ is unbounded, strictly increasing sequence of positive reals Let $\{a_n\}$ be an unbounded, strictly increasing sequence of positive real numbers and let $x_k=\frac{a_{k+1}-a_{k}}{a_{k+1}}$. Which of the following statements is/are correct? (CSIR NET December 2014)         For all $n\geq m, \sum\limits^{n}_{k=m}x_k&gt;1-\bf{\frac{a_m}{a_n}}$   There exist $n\geq m, \sum\limits^{n}_{k=m}x_k&gt;\frac{1}{2}$      My attempt:  Analysing question in light of $a_k=k\implies x_k=\frac{k+1-k}{k+1}=\frac1{k+1}$, I feel both are correct, I doubt if  I can generalise the result in light of this one example.   Any way to prove that this true for general case?    Note: Please do not confuse  with my question. The first two options are different, I've marked the difference in bold. How do I choose an element from a non-empty set? Suppose I have a non-empty set $A$.     How do I choose an element $x\in A$?   More precisely, I believe I would like to find a formula $P(x,y)$ of ZF such that for every non-empty set $y$ there is exactly one $x\in y$ such that $P(x,y)$ is true.  I have thought about this for a while without success and I am beginning to doubt such a formula is even possible. But in mathematical proofs it is quite common to "choose a fixed element" from a non-empty set. So how exactly do we achieve such a thing? Am I missing something?  Thank you in advance. Finding a 2x2 Matrix raised to the power of 1000 Showing $d(x,y) = \frac{|x-y|}{1+|x-y|}$ is a distance. Show that $(\mathbb{N}, d)$ is a metric space   with $$d(x,y) = \frac{|x-y|}{1+|x-y|}$$   My attempt:   let $x,y \in \mathbb{N}$,  1) $d(x,y) = 0 \implies |x-y| = 0 \iff x = y$  2) $d(x,y) = d(y,x)$  3) show for $z \in \mathbb{N}$, $d(x,z) \leq d(x,y) + d(y,z)$  Using the triangle ineuqality I managed to get:  $$d(x,z) \leq \frac{|x-y|}{1+|x-y| - |y-z|} + \frac{|y - z|}{1 + |x-y| - |y-z|}$$  but i assume here I must use the fact that $x,y,z \in \mathbb{N}$ but I'm not sure how.  Any hints please:  edit: improvements on solution - Using fact that $|x-y|$ is a metric we have that $$d(x,y) \leq \frac{|x-y|}{1+|x-y| + |y-z|} + \frac{|y - z|}{1 + |x-y| + |y-z|}$$ (Since $|x-z| \leq |x-y| + |y-z|$) Is this correct? From there I can use the fact that $$\frac{1}{1+|x-y|+|y-z|} \leq \frac{1}{1+|x-y|} $$ and $$\frac{1}{1+|x-y|+|y-z|} \leq \frac{1}{1+|y-z|}$$ to conclude? What is scientific mind? How can you define scientific mind? What i think , it is a bend of mind that can be developed by any person(also one not related to field of science).This mind is fulfilled with abilities to observe clearly and sceptical about what he sees.It means the person will be keen to dig out truth and did not reaches to a conclusion easily. He utilizes facts enhance them with logical reasoning and fills the gap with their imagination.  Is there any disadvantage or any kind of limitation with scientific mind? Adding CSS Reference on Site Page uwsgi errno 24 too many open files on CentOS / nginx Cannot add a NOT NULL column with default value NULL in Sqlite3 Assuming there are 5 items in the settings file (MySetting1 to MySetting5), why does PropertyValues have 0 items while Properties has the correct number?

Is there any way to get around this restriction without going the fully custom route to do so? Is it possible to create a "weak reference" in javascript? Is there any way in javascript to create a "weak reference" to another object?   Can anyone think of a way to implement this  behavior in javascript? PHP parse_ini_file work on URL? Two question on harmonic function I'm about to start exploring the world of long exposure shots, using my Canon EOS M. The camera has a standard max exposure time of 30 seconds, but in bulb mode I can keep the shutter open indefinitely (using a wireless remote to control the shutter.)  How long can I leave the shutter open without running the risk of prolonged exposure to light damaging my sensor?  For the purposes of this question assume I'm shooting in summer daylight, so that we can go by the worst case.
