Thanks for all the advice as far as photoscanning goes. My results are getting a bit better. I'm still having trouble working out a good pipeline though. I want to touch up my scans in Zbrush, but I don't have much experience there. I want to close the holes and fix up distorted parts of the model, but I still want to keep the high-res textures that Photoscan generated. I was thinking that Dynameshing the scan, then fixing up the model, then projecting the textures back onto the resulting model and UVing it by hand would be the best way to do that. Is that the general workflow that you guys do? I'm trying to get something that could be used in UE4. The other thing is that Dynamesh just crashes Zbrush so that's a kink in the plan too.

Rubber Slug posted:Thanks for all the advice as far as photoscanning goes. My results are getting a bit better. Dynamesh crashing is a serious problem, but I mainly use it to close holes. Regardless if you dynamesh or not, you can still decimate the mesh. Sometimes dynamesh will work better if you decimate first. So.... follow this order: 1. Decimate at high detail. This is dependent on how decent your computer is but the important part is to keep as much detail as possible. 2. Dynamesh if you can in order to close holes. 1024 or higher is best I would say. Again, try and keep your detail from the scan. Turn polish / blur OFF / zero. If you don't need to close holes you can skip the dynamesh. 3. Retopo or zremesh (with low settings. 1 or even lower for base mesh) Note: It is always best to draw guides for zremesher. If you have the time / patience just do it in Maya / Max / Topogun for best results. 3D Coat is another popular option. 4. Project details from decimated scan into new retopo or zremeshed mesh. Best to do this at lowest resolution first. Zremesh / retopo should be the subtool OVER the scan / decimated data. 5. Subdivide retopo / zremesh and project details again. Subdivide and reproject until you have all the details from the original scan. Very important to project from lowest subdivsion to highest, one step at a time. 6. Now you should have mesh with good topology but also has the details at the highest sub D. Unwrap UVs of the new mesh with whatever tool you want but UVmaster should work for something quick and dirty. 7. Export new mesh (with good topology) back to photoscan and create texture. Make sure to tell photoscan you want to keep your UVs. Export texture from photoscan. 8. Apply new texture from photoscan to retopologized model with good UVs in zbrush. From here you can make your normal maps in zbrush (or mudbox, but I prefer xnormal). Have a drink. Note that the drink is optional, but you may want one after getting this far.  Pretty much my workflow for this. sigma 6 fucked around with this message at 03:11 on Mar 12, 2015 |

^^^ These days, the lightbox has a quicksave menu which keeps an autosave every 15 min or so. ^^^ One of my first attempts was scanning a buddha statue. Here is my latest attempt with the same statue. Thanks to Gearman for the help with masking in photoshop. Definitely saved some time with that.  One thing I learned is to NOT put your object on a colored platform. Notice the red bounce light on the feet. It was on a red utility stool. Woops.

 I redid the face and re-detailed the body. Now i'd like to do the clothes again. It turns out that 3dsmax has a default cap on the resolution that maps will display as, so i was agonizing over why it looked so poo poo, which kind of helped me to learn how to use cages in the quest for a good bake.

Ledenko posted:To 3d pros: is this type of modeling marketable? Is there such a thing as product visualizer? I'm trying to escape low end IT and this stuff seems to suit me nicely. Absolutely. There's a pretty good demand for product visualization out there, especially in the automotive, electronics and beauty / cosmetics industries. Some people also specialize in modeling and rendering jewelry. I don't know enough about the product design industry to comment on the relative difficulty of actually finding that kind of work, but it's definitely out there, and I think there are a few industrial designers who post in this thread sometimes who can hopefully help you out further. Oh, and your model looks quite nice as well. What did you use? Rhino?

Thanks! I used mostly Moi3d and Rhino in cases where Moi would not create good continuity. I'm also following a tutorial for making an Audi R8 in Rhino and that's turning out pretty nice as well. I only started doing this about a month ago, still learning as much as I can when I have the time, which is not a whole lot with a full time job. If I could find a gig that would pay as much as my current job, I'd be perfectly happy - I do realize that won't happen overnight though.

If you notice in the image I sent you, my platform is a mid grey for that very reason. I went and found some paint that was very close to 13% gray (using the digital mid-gray instead of the typical 18% for most non-digital cameras) for my base, but any light gray is perfectly fine. Also I recommend getting your statue up off the platform if at all possible. It'll help reduce those bounce colors and eliminate some of the ambient occlusion around the base as well.

Thank you Gearman! Will definitely put something over the stool next time, or paint something gray, as you suggested. I have heard of using gray spheres or something for color correcting but I never thought to do it for this. Do you know the pantone color for that paint by any chance? I wonder if I can just buy something similar at Home Depot? Why are you choosing gray over white for keying out the background? Scanned a barrel earlier today as a demo for a friend and tried out sketchfab for fun. Embeds well in facebook but not here for some reason. Barrel EDIT: Updated the Buddha on sketchfab with a much better texture (and lighting) vs. low res polypaint. No other maps yet though. Gotta admit, sketchfab is pretty cool and not too hard to use either. Buddha

Don't have the pantone for it off the top of my head, but I might still have the name somewhere. I wouldn't go too crazy over it, and its probably not necessary to get an exact match. I went with mid gray because I can meter to the area and not have to worry about the exposure being off a bit. Also I'm quite lazy and if I don't have a color checker or a gray card on hand I can meter and white balance off the turntable itself. In addition, it helps mitigate bright bounce highlights a bit, which is a nice bonus. My backdrop is solid white. Both are very easy to select and mask out before processing.

Hi y'all, I'm looking for some advice on placing 3d assets into to aerial footage. It's been about 3 years since I've done anything like this and back then I used syntheyes->Maya->AE. The stuff I am going to be inserting is simple building models from developer firms (CAD models? Image below) and something a little nicer for my clients demo reel. Both my client and his clients have a pretty low bar for quality, I'm looking to be on par with sci-fi channel VFX (and I've done that before on a couple of occasions). Mainly I want some advice on camera tracking and 3d software. I've used AE's 3d Camera Tracker and got some ~ok~ solutions, nothing I'm terribly happy with. I know about the Tracking Tool and will play around with that next. I haven't tried to export any camera's yet. I guess I want to know if AE's tracking solutions are going to be suitable and I just need to learn them better or if I should use a 3rd party thing like syntheyes. For 3d software stuff: I know Maya, I'm comfortable and fairly quick with it. I've done a little 3DS too. I remember it having a lot of presets for architectural type stuff and I found getting a good render was a little easier. I am also curious about C4D, and since I do more and more mo-graph stuff I probably should get into it some. What would you archvis pro's suggest for 3d software in this fairly specific case? Is this a CAD model?

use syntheyes, export camera and points to maya and render/match lighting in there. you'll also want to get a copy of fusion now that it's free - don't just render the building into the footage, render it with the lighting as close as you can get then color correct the building and footage separately to get them to match better. personally i'd use max instead of maya but I doubt it makes a lick of difference in the end result. syntheyes and fusion i wouldn't attempt this without though.

Also as a alternate route I've done this a few times lately just matchmoving in AE CC 2014 (their camera track is getting quite good) and just importing my model directly into AE via Element3D v2 and going from there. You have control over lighting, shadows, and reflections more with Element v2 so you can get some quite nice results. It's great for quick projects that can still look good. But yeah delving deeper into syntheyes and Maya is gonna let you up the game quality wise.

I keep forgetting that Element 3d is an option, haven't successfully warez'd that yet but it's affordable and I could talk this guy into it. I think I'm just gonna stick with syntheyes though. Me not being satisfied with AE's camera results is gonna stick in my throat. And yes to HRDI lighting, dudes already on site and he likes gadgety photography things. Might as well show him how to get the source material for it. Fusion is this one right?

I believe he was referring to the compositing package, recently acquired by Blackmagic Design: https://www.blackmagicdesign.com/products/fusion You basically get a NukeX-equivalent toolset for zero dollars. Pretty loving cool. I'm hoping they do a proper OS X port sometime soon.

What is wrong with Maya 2015? Their interface is becoming more and more unusable and buggy. I mean it's a goddamn chore just every trying to select the right component or object mode. It used to be all so easy but now 9.9 times out of 10 the tool gets stuck on a component selection mode or trying to go to group selection mode keeps putting the object into component selection mode and just on and on. There is no way to seamlessly edit an object any more as I have to constantly click off an object and reset my tool settings just to get them to work again. It's a mess.

I dunno, man. My markup menu might get stuck in a specific mode maybe once a week (12 hour days at the moment), but otherwise it works the same as it always has for me. I'm looking forward to them getting around to fully integrating the modeling tool kit tools, because having to quit out of it's OWN, SEPARATE COMPONENT SELECTION MODE is pretty STUPID. That and it crashes a lot more than Maya 2014.

People were saying Maya 2016 was looking pretty strong but I'm still waiting to see what the announcements are going to be. Given what they announced for the LT version it at least sounds like a lot of the modeling toolkit stuff will be better integrated. Also, yeah, I don't have a lot of crashing problems with 2015. The worst thing right now is the acknowledged memory leak in the UV editor. That is awful.

I can't wait to start using it at work.

Yeah that's basically my feeling. As with any kind of plagiarism the thief is ultimately only hurting him or herself in the long run by misrepresenting the quality of work they are able to produce, and as mentioned if it's a serious thing there should be abundant ways for you to settle that dispute in your favor.
