The idea was to combine photometric stereo and photogrammetry where I could derive real height data and not some sort of made up height map based on normals.

So the setup in that video was a bit finicky, because it used some off the shelf gear belt thing which forced me to build up the rotating part of the polarizer because that ring is only about 4mm wide and the belt was closer to 1cm. So the tape would get soft eventually and the belt would lose tension. Eventually I just 3d printed a gear that could be press fit onto the polarizer and was very reliable. Initially I had it printed in a rubbery type material, thinking that the flex would allow me a little stretch to get the gear on but this just caused it to bind up, so the solid material was the way to go. As for servo vs stepper, I learned as I went along and just figured how to use steppers so I used them, were also cheaper. The whole project is shelved at the moment but I ended up making a stepper mount that attached to a 3d printed bracket that mounted to the end of the lens where hood would mount. This allowed the ability to zoom in and out without having to adjust the stepper on the rails, the downside of this is that the print is lens specific.

@@AlexCowan3d something like that ? kzbin.info/www/bejne/mpDXe5-frM5qn80

@@darty367 yup pretty much.

​@@AlexCowan3d thk Alex, it inspire me to make similar stuff for my work, if you want show your design feel free to share

​@@AlexCowan3d I forgot to ask you what kind of stepper motor and controler do you use ? It seem a nema 17.

Thanks

I wasn't planning on it, but is there anything specific you are interested in me covering?

@@AlexCowan3d is there a way I can contact you?

@@kylisation you can get my email from www.acowan.com, or message me on artstation

I just used some of the UE4 cinematic camera tools rotated the camera crane around for one shot and then camera on a path for others. It isn't covered in the course but there are many tutorials out there for this stuff, the most difficult thing might be that UE4 changes so rapidly that certain tutorials are out of date but other than that it is pretty straight forward. During the course focus on the foliage and making the scene great, you can do the video parts later.

Thanks a lot!

GuzZ XtreM Thanks man. Prior to taking the course I had pretty decent knowledge of zbrush but I mostly sculpted environmental things like rocks and stonework. So while I did know zbrush, I didn't have much experience with sculpting more organic elements and was a bit rusty too. Once you know how to navigate zbrush you should be fine. With UE4 I also had prior experience, but the course doesn't go into anything too complicated and the things that might be a bit tricky are well covered. I will say though that there aren't any magic tricks in this course, but if you follow the instruction and put in the necessary time you'll get something awesome out of it.

Thanks for your answer. Do you think that it's possible make this course with 3Ds Max ? What course or tutorial can you recomend me for get skill with zbrush for environments ?

I'm pretty sure you can use 3Ds Max, he builds the tree trunks by extruding polygons along curves and Max should have something similar. The rest is just cutting out and placing leaf cards so it shouldn't be too complicated. For this course any simple zBrush tutorial that familiarizes you with the interface should be sufficient.

Yes I started this scene for a CGMA course. www.cgmasteracademy.com/courses/60-vegetation-plants-for-games

so the course its old but they sell it every season ?

I think the Vegetation course fairly new, I was in the second batch of students through it in the Fall semester.

it look the best course for ue4 , and you did awesome work in the environment

1 more question , if i bought this course am i able to download the videos ? because i have internet bandwidth limits
