Alex if you're reading @ 1:31:58 You can do it in photoshop, it's the same with PNG format just go Layer->Layer Mask->From Transparency. Then you can just disable/delete the layer mask, Happy Xmas! :)

@agisoftmetashape3247 7 жыл бұрын

Actually, PhotoScan v. 1.3 allows to disable saving transparency in alpha channel for the texture during the mesh export, so it should be more convenient now.

@Shamanix 6 жыл бұрын

Agisoft, may be you finally learn about Associated Alpha and Unassociated Alpha? xNormal generate tiff with alpha that open in Photoshop as Image + alpha channel because alpha still can be needed. Or any evolution is not about your company, like your app still on same age with bundler while other tools used modern methods that faster and better?

1:16:50 into the video, Creating Photogrametry from a turntable, masks where created to separate from object the back ground. But at the time 1:16:50 in the video skips and important part where aligning images you are supposed click "Constrain Features by Mask" (under advanced options in the The Align photos window). If you don't click this the images will not align. So if you are the turntable method, Be sure the check that option box when aligning the images, or else you'll spend a lot of time wondering why your point cloud and mesh are unusable.

Amazing technology for gaming. The dead end with no reward is when the game is indistinguishable from reality. Only the gaming experience can be advanced through intuitive gameplay custom made to the individual. The future of gaming, like art, will be compelled to progress into the abstract because there is nowhere to advance to once everything is like reality. Within the abstract will be lower poly textures to induce various feelings. Something to think about in the hi res goal which will eventually backtrack. Minecraft is a good game, question why.

@arielshtern4125 5 жыл бұрын

But wait, for projecting the textures, you import the high res model from Zbrush to MetaShape? Not the UVed low res mesh?

dont subD to the final asset resolution. SubD once .. then project ... subD again .. then project and again .. until you're back up to the high res level. Then you avoid messy projection.

@knightwalkr 7 жыл бұрын

Andrew Knight I play with agisoft a lot. The short answer is it seems to give a better point cloud result. For a long answer I'd say you'd need to talk to agisoft devs. But i don't get as many empty holes as he seems to. But I carry a mono pole and use an app on my phone to control my Nikon. I put the camera on high odd angles and try to fill in random exposures. But this won't work with say an 80 foot tall tree.

@Elvoril 7 жыл бұрын

thanks! Does he skip over the step to re-import his adjusted photos? not sure how he re-adds them in.

Does anyone have any idea as to how he went about shaping the black areas for the alphas in photoshop? He said that he paints in black around the edges, but they seem very perfect and random. I'm wondering if he maybe uses a technique that he didn't show. I've heard of using color burn to get a similar effect, but it never gives me good results from the docked zbrush textures. Any ideas?

@worldlearner0411 7 жыл бұрын

For anyone out there that is trying to figure this out.....Through a combination of levels and using the burn brush set to shadows you can get this affect :)

@AlexAlvarez__ 7 жыл бұрын

Hello Tony.... yeah, I did just paint the edges black with the brush tool in PS. One alpha at a time....

@worldlearner0411 7 жыл бұрын

You are a soldier lol Using a black brush is very hard. No matter how much I tried I simply could not get a good look. I had remembered a masking technique using the burn brush and setting it to shadows. Seems to work pretty well. Thanks for the great video :)

Is here someone who tried it with blender instead of zbrush. In case someone is. How can I fix the holes in the Mesh, the solution in Zbrush is easy with the dynamesh but i couldn't find anything similiar in Blender. Cheers, Anton

maybe I'm and idiot. I did all the steps and then I wanted to import my HP Mesh Back into Agisoft. What a surpirse, my model does not go at the same spot of my Dense Cloud. And I didn't moved the object at all. Imported it into maya and its at the origin. What have I done wrong ? Thanks for any help

@anti_blu 6 жыл бұрын

problem solved. Obviously i moved it. My solution : exported the mesh from agisoft again. opened it in zbrush. Copied the export values - paste in my actually zbrush file. exported the model and it worked !
