Best texture settings for photogrammetry

I’m wondering what settings people are using to create textures for scanned people with photogrammetry. I’ve been playing around with them and I’m not sure what does what.

Hi Marcus Milne

in UNWRAP set gutter to 2, texture size 8k, max textures 1. Then in RECONSTRUCTION -> SETTINGS -> COLORING/TEXTURING change IMAGE DOWNSCALE BEFORE TEXTURING from 2 to 1 to get max texture resolution.

thank you. It looks like my settings are the same. Is there a way to turn off some of the images used to build the texture? Sometimes I like to render the texture only with the photo of the face instead of using many photos of the head blended together, because I get a clearer texture.

I figured it out. I can just disable images in the 1D view. I don’t know how to disable a whole selection though. At the moment I have to click on each image

Easy way, just select a camera and DISABLE it for TEXTURING.

Select the cameras and in the 1Ds view you can DISABLE them.

Ok I got it. I have to change it under “Selected input(s)” box below. I need to change “Enable texturing and coloring” to change all images in my selection.

I seem to have banding in my texture output. It looks like a lot of little strips put together. Maybe its because the lighting is not consistent in my photos. But I never had this problem with Photoscan. It looks like here the images are merging too many times to create the texture. Is there a way to change the settings so the texture does not take so many little strips from the images, but takes larger areas instead?

Hi Marcus Milne

try to change the texturing mode from VISIBILITY to PHOTOCONSISTENCY and generate the texture again.

Are you using fixed camera rig or a turntable ?

I’m using fixed cameras. I have 82 but my lighting isn’t consistent.

Ok what I did was create texture maps for front, left, right, back and face and just used Gimp to merge them together the way I want.
