See the video description - this solution isn't working post version 4.25.

@@bobthechemist Ah - well that makes sense then. LOL

A number of visitors have had problems getting this solution to work post version 4.24. Additionally, it does not appear to be possible to do in UE5; so I think the answer to "...what could have happened" is "Epic happened." They went in a different direction and my solution is no longer viable.

Good question - I haven't tried to replicate this behavior in a UE5 project yet.

@@bobthechemist okay thanks

When I tested, it was first 9 techniques for shodan and all 15 for nidan (USJF). Rules have changed, and now it's a bit complicated since the requirements are different for competitors and non-competitors.

@@bobthechemist Cool I was just wondering what the requirement for the Nage No Kata were. Thanks for answering.

Hah, thanks. Last summer our sensei had us do a deep dive into one particular throw. Spent 8 weeks on Harai. Might have gotten it to an 8.5.

I'll look; however, the video is from 2014 and I don't think I have that spreadsheet any longer. Sorry.

When I see that, it usually means the player start overlaps with the map floor/wall. I'd try moving the player start to a spot where it is definitely away from all objects to see if that solves the problem.

Certainly possible, last time I used 3D text was when it was unstable, so I'm not the person to ask for that part.

Thanks - was a fun project.

this is good to know, I found that print string while doesnt show in unreal engine running, it does show it in the text logs

Yes, as mentioned in some comments below, this method was broken in 4.26. There is now an UnrealEditorSubsystem that is required to find/use "Get Level Viewport Camera Info" and even then, Editor Utility Blueprints don't expose events and functions to the Details panel. "Snap object to view" solves the named-problem (placing player start) but a new solution is needed if you want access to camera information while editing.

@@bobthechemist My apologies, I wasn’t meaning to retort the content in your videos. Knowing internet tutorial watchers, I imagined many probably want the”EZ” out of the box way, and my comment was for them. Again, my sincere apologies, I should have been more aliterate.

Still waiting for someone to gift me a HoloLens 2, so I don't know for sure :-). My intuition tells me that if the HoloLens 2 can handle network traffic, then it can handle this plugin.

@@bobthechemist Hi Bob, No worries at all !! But this was a great tutorial, I tried it in HoloLens 2 and it worked flawlessly 😄thank you so much for ur efforts into the content that literally saves the day! Cheers!

Awesome! Glad it worked. Good luck with the project.

I don't think so with this plugin. It does not do generic web scraping.

@@bobthechemist how do you think I would get around this problem?

@@bobthechemist is there any other plugin that can do scraping inside unreal?

@@3jsjeosn I have never searched for a web scraping plugin for unreal. If I were interested, my approach would be to see how the experimental Python coding in UE5 works and then use the webscraping libraries (e.g. BeautifulSoup) available in Python.

Good to know. I plan to check out UE5 this summer and will keep an eye out for this problem.

If there is, I don't know about it. Semester is almost over and I'll be able to play with UE again....

@@bobthechemist Hey, thanks for the response! I get it to work by not using any kind of authentication, I've used an API that is called gsx2json which transforms any google sheet on a json object and than I process it inside Unreal

If you're looking to post json data to a website and then retrieve that data in UE, io.adafruit.com/ might be a good (free) start. Note that this solution would be limited to a relatively low data refresh rate, but would teach the process.

@@bobthechemist Sorry what solution ? I only see the adafruit website mainpage? you meant a specific tutorial there?

Adafruit's IO tutorials are here: learn.adafruit.com/category/adafruit-io. As for "solution" I mean that the Adafruit IO only refreshes data a few times per minute, so you couldn't use this approach for things like real time positioning of enemies in a game.

@@bobthechemist ah no , all I want to do is retrieve a sensor data like humidity or temperature , send it to a website with a nodemcu and write it somwehre so that I could get it from Unreal with the Varest plugin and display the results ingame or have some other interaction there, the most I woul dlike to do it on a personal website but I have no idea how to make that to work and write/display json data there.

My other vid (czcams.com/video/DifFzUQgVzo/video.html) might be a tad helpful. It uses a particle to post data to the web which I grab in UE. The library would be different since I'm using a particle and not a nodemcu, so YMMV.

Wow, someone's checking out my deep tracks :).

Glad it was helpful!

That's correct. In fact, u is usually the standard deviation (sigma); however, there may be times where you need to use the (manufacturer supplied) tolerance or some other measure of uncertainty.

​@@bobthechemist thank you sir. Can you please help me with the following problem? If i have a cube with edge length 11 with standard deviation 0.6 and you want to know the standard deviation of the volume of the cube. If I use the multiplication formula the sigma_cube = 11^3 * sqrt( (0.6 /11)^2 +(0.6 /11)^2+(0.6 /11)^2 ) = 126 But there is also a formula for powers,if f = a*(A^b), then sigma_f= abs( (f *b*sigma_a )/ A ). if I use that I get sigma_cube = ((11^3 * 3 * 0.6) / 11) = 218. It should not be that these two formulas give different results, what am I doing wrong? Thank you again

@@user-kl4oh2co2y This is a tricky one and depends on what you know about the cube. The question you must ask yourself is: "how many measurements have I made"? If you measure *each* side, then you have made three measurements, with the appropriate formula for volume being V = x1 * x2 * x3. If you assume that all sides are equal, and only measure *one* side, then your formula is V = x^3. Because each method has a different number of measurements, they will have different uncertainties.

​@@bobthechemist thank you sir, my situation is different. I "reshape" 2d images of sphere like shapes into cubes by taking the area of the circles and converting it to a equal length square with the same area. I do this for thousands of circle like shapes and get a standard deviation of the edge length. Then I convert the square to a cube and want to know the standard deviaton of the volume of the cube. This means that I have to use the power rule? I am still confused why this would give a much larger stand.dev. than using the seperate sides, you might have less measurements but why does that matter if I know that it is an equal edge length cube? The difference is huge. Thank you.

I cannot give you a definitive answer as to why the two approaches give different estimates of uncertainty. You could visit the link below for the calculus behind error propagation. The important takeaway is that variable covariance is not considered in this approach. That is one reason why the a*b*c formula results in a lower error than the power equation. Do note the caveats to calculated uncertainty in the link; if you have the opportunity to make a direct measurement of the error, it is preferred. chem.libretexts.org/Bookshelves/Analytical_Chemistry/Supplemental_Modules_(Analytical_Chemistry)/Quantifying_Nature/Significant_Digits/Propagation_of_Error

I'd love to, but I haven't done any PHP programming, so I'm not the best person to follow for that task.

Glad I could help

You're very welcome!

Nice! Congrats. I hope you get a chance to make cool stuff.

I haven't done that, and it's probably out of scope for VaREST. Have you seen this? czcams.com/video/RRvzRxxUhcg/video.html

Hmm, might be out of my league since I have no experience with Visual Studio. Since internet JSON strings seem to work, my first thought is the WEB.API is doing something different from what VaREST expects.
