ABOUT ME
I've been using Blender for over half my life! That's since 2008. My first freelance work with the software was around that time as well. I did some animations for a waiting room in my local dental office. Since then, I've been hooked earning a living providing 3D services for businesses across the world. I've had the chance to do work for some big organizations like NASA and Microsoft. The real pride in my work though, has come from helping and being involved with small, independent productions. These indie productions and creators embody what it is to me, to be an artist.
Nowadays I spend my time making 3D models, textures, and training material to help get these solo creators and small teams off the ground and running. You can find everything I'm working on in one place, over on the site I built from scratch: www.rileyb3d.com
I'm very proud of it! I ought to be with how much time I've put into it. 😅 It's the catch all site to access everything I create. Supporting me there is as simple as contributing the cost of one coffee per month. Doing so gets you access to all training material I've ever created. For a slightly higher support tier, you get access to my ENTIRE model and texture library! Higher still, and you'll receive recognition in all of my video and site footer credits.
Some people ask why I don't have a Patreon. This site is all about creating custom and exclusive offerings for artists. Your monthly contribution is no joke. In fact, it's my complete livelihood at this point! I don't think it's responsible for me to give away a cut of your money to third party organizations like Patreon, so it stays with me, and goes directly towards producing more content and resources.
this quality is insane! Thank you so much
That was amazing. Good job bruv
wow man, this is an outstanding video!
That's pure gold! Tkss!
Really glad you find it useful!
Top quality stuff, invaluable. Thank you so much!

Great video, and great explanation of cross-polarization. As far as software goes, there are a few options for constructing photogrammetry scans. A neat one is Meshroom, which has a Blender plugin and is open source.
Great point! I'll have to check out that plugin. I cut this bit from the script due to time. It could also apply to Meshroom:
"Polycam excels in convenience and mobility. In the rare case I get something unexpected happening with my scan, and I need more hands on tools to troubleshoot, I might jump into Reality Capture as my backup. This will give me more debugging options if I need them, but these days I’ll use Polycam for most scenarios."
This was such a good video.
Is there any benefit to polarization on the lens, without polarizing the light?
You will definitely see a benefit even with just a lens filter. If you're only going for one end of things, I'd start here as it's also cheaper.
Great video! I love the CG part, took me a moment to realize it wasn't real! I guess you also scanned your equipment?
You can save a lot of money on your setup, if you buy a foldio 3 lightbox and turntable. By the other hand, with an entry level camera like a nikon d5600 will be more than good enough.
I haven’t tried this light box but it looks good for small objects! Could be a good desktop option.
Also, definitely yes on different camera options. There are many that could work well.
@@rileyb3d foldio 3 is the big one and the best for me.
Hum, seems my comment got lost 🤔 Anyway: I appreciate the amount of work you put into this video and the quality you produced! It was a pleasure to watch 😊
I have a question. The polarizer is already composed of two polarizers. Rotating and crossing can effectively remove the highlights. Why do you need to control the direction of the light source?
Which method was used to create the into/outro sequences? I’m guessing not the basic setup?
Fabulous content, thanks. One question: the link to the polarizer for the camera lens says it’s circularly polarized but I got the impression that linear was the way to go based on the video graphic. Is the link correct, the graphic “not particularly accurate,” or am I missing something? I’d bet the middle case because two linear polarizers at right angles should block all light, at least in theory, but I’m no pro. Thanks!
Excellent question. So for both the linear and circular polarizer, the light is being polarized in a linear fashion as demonstrated here in the visuals. For simplicity in the tutorial I didn't get into it, but the difference is the circular polarizer has an additional layer called a quarter-wave plate to make it work with modern mirrored cameras. The difference is negligible IMO, but still. Apparently a linear polarizer will mess with a mirrored camera's metering and autofocus.
Long story short, you're safe with a circular polarizer no matter what camera you use, so that's why I recommended it here. It's a safe purchase for everyone. Again, the light is linearly polarized as shown in the video, it just has an additional layer to work with mirror cameras. It will also work with mirrorless.
If you have a mirrorless camera, metering and autofocus work directly off the sensor, so light isn't mirrored and bounced around to different locations in the body. A linear polarizer would work fine in this case.
@@rileyb3d Wow, that was quick! Big 🙏
@@rbrown2925 Just read my response and I'm wordy lol. TLDR go for circular in most cases.
Is Polycam free to export your model, though?? I recently got my first ever iPhone (11)and have used Photo Carch for some pretty sweet results entirely oh my phone with it's megre 12MP camera
You’re right, I believe their export options are limited until you pay. I can check out photo catch. Though, desktop uploading is a must-have for me.
