This thread is dedicated to the wheels and the rear axle of the backhoe project.
Strange..I can't imagine why streaming a video would be so RAM intensive on your end. Since we're using Youtube (popular, well-established platform) I wouldn't think it's anything I can fix as the streamer..BUT it just occured to me: I wonder if it's our website's chat system. I've seen that thing slow down significantly.
I'll rope in our webdev @nphaskins to see if he can look into the chat being a potential problem. In the meantime here's a few things you could try:
Sorry for the issue. That's a major buzzkill when a stream is going on 😕
@theluthier thanks for tips. Jonathan's livestream on September 22nd will be the next opportunity for me to test how I can avoid this problem here on this website. It just came to my mind that my browser probably tries to store the livestream video data on my computer in order it faster just in case that I would like to rewind to an earlier position and that I can maybe switch this behaviour off. The high memory consumption points imho rather at video data than the chat with its tiny icons as the only graphical elements. But I'm just speculating.
If you hop over to a random live youtube channel right now that should be definitive proof of the issue being the the video data or not. Watch one of those for 10 minutes or so and see if your computer struggles with it similarly then we'll know it's the video data. If your computer doesn't struggle then it must not be the video data. Since every YT streamer's data passes through YT's servers.
Kent, I've found a Blender "Titanic Modeling" livestream🤩 running since 75 minutes with around 20 viewers!!! That's a project which I had in mind as a future CGCookie collaboration project😀!!! Alternatively a Space Shuttle or a Saturn V moon rocket .
The memory consumption is oscillating around 3GB for firefox.
This Titanic CG modeler seems to be a Bob Ross fan and he was just talking about his wish to have a time machine in order to travel back to shortly after Bitcoin had been released. With an investment of 200 Dollars he now would have made 27 million Dollars. If I only had known this earlier ... How many Caterpillars 434E could I buy with this. And what would a Titanic rebuilt cost today?
The "Titanic modeling" livestream is at 720p and everything is running smoothly 😀 with a memory consumption at 4,2 GB and the AeroBlade 3D Fan showing a higher activity. I think, 40 to 50 minutes in the backhoe livestream was when problems began.
It's now 45 minutes in the "Titanic modeling" livestream and the guy has just finished (10 a. m. where this guy is living) for a break of an hour in order to relax and hoping for better weather (hurricane season). Kent, maybe this guy isn't living far away from you (at least for US scales 😉)
Sounds like an interesting livestream! I used to be obsessed with the titanic as a 10 year-old kid. Can you link me to the channel?
4.2 GB still seems like a lot to stream a video...I've got 2 chrome windows totaling 20 tabs and I'm only at 2 GB (Chrome is also a known RAM hog). Do you maintain a lot of tabs in firefox when browsing?
The channel is called "Titanic Animations" and can be found here. This guy has really dedicated himself to telling the story of the Titanic and her sister ship:
"Started out with very little animation and modeling knowledge, but a passion for RMS Titanic which spans back to 1995. Now I plan to tell the story of Titanic, and her sister ships, to keep them alive for future generations. "

If I type "about:memory" into the internet address field of Firefox, then I get among others a button "minimize memory usage". But I've also read that Firefox is known as a "Memory Monster" 🤪. VLC player can be used for streams too but some streams crash after a few seconds. I've read furthermore that Windows forces Firefox too rarely to free memory. There's last but not least a recommendation to use the 32Bit version of Firefox even on a 64Bit operating system due to a lower memory usage.
Sounds to me like the issue has more to do with your browser / computer than what I should do as a streamer. We always want to provide the highest quality video, whether pre-recorded or live broadcast which means high bitrate transfer of 1080p video. To reduce any of the settings is costly to our standard and could result in Blender's UI being pixelated and hard to distinguish for viewers. I could avoid the "Ultra low latency" option on Youtube but that would mean 10-20 second delays...I think that significantly hinders the viewer experience.
For the next CGC stream you watch I recommend trying these options:
Hopefully that improves the experience from your end!
With "about:performance" typed into the internet address field of Firefox, the built in "Task Manager" shows me that for example the "Shading the Grass Field Mesh" lesson of Jonathan's new shading and texturing course already uses around 330 MB of memory.
I've dowloaded today the current "Master Assembly" and "Parts" files for our "Dog" backhoe. The axle rims and hubs which are duplicates of the corresponding front axle parts need to be hidden so that my rear axle rims and hubs are fully visible:
View with front axle rim and hub duplicates:
Without front axle rim and hub duplicates:
Eight bolts and nuts of the rear axle are slightly intersecting with the chassis:
Both sides seen from inside the chassis:
The hoses from the rear to the front are floating in the air and without connection at the front end:
Yes, these duplicates are those from 
spikeyxxx 's front axle copied to the rear axle. They just need to be made invisible by unchecking the screen icon (for "gloabal visibility") in order to affect all files that are linking spikeyxxx ' s axle . The eye icon doesn't work for that purpose as I had to learn. I've already done this locally on my computer before taking the second screenshot in this post here but off course I can't do this unauthorized on the files of other citizen members on Google Drive.
Thanks duerer
@theluthier how do we want to handle this? Can you turn off this duplication on the master file and confirm this resolves the issue from the comments during the live stream and Ingmar's posts?
OK I think I sorted it out duerer. I opted to keep Spikey's wheels + rims for front and back for consistency. I added the intersecting parts of your rim to a collection outside the MASTER collection called "rims". This way they remain part of your master file but they aren't included in the master assembly.
Ingmar duerer I think the axle definitely deserves a nice Ingmar stamp on it. That thing is a true work of art my friend. There's a couple of nice flat spots to add one if you are up for it.
