Problem with using panoramic image for texture building

[maddin]

So I have this project of about 300 aligned DSLR images, along with a few full-spherical panoramic images, also successfully aligned. Also, I successfully computed a dense point cloud on 'High' and a mesh with about 2.9 Mio. faces.

Next, I do a Build Texture > Single Camera - but PS just sits there, trying to generate the texture atlas needed for this single (panoramic) image and never returns on me. I left it sitting at 0% progress bar for 45 min. but no apparent progress was made.

Note that I can use 'Keep UV' and disable all cameras but the one panoramic image and this works fine. So it seems not to be the actual projection of the image data but rather the generation of the UV coordinates from a single panoramic camera that is the problem.

Anyone else encountered this before?

Hello maddin,

Have you tried to build the texture on low poly mesh - how long does it take? I've ran a quick test with only two spherical cameras and it worked rather fast.

Just tried it on a low-poly imported mesh (544 faces, basically a big cube with a few extruded details; the project is about a room interior). This worked, took about 30 sec, but the result is broken. The UVs generated by PS look pretty bad in Tools > Mesh > View Mesh UVs...
Somehow the UV generation from a single panoramic image (should be a simple spherical projection withe the camera as center?) seems to be broken.

Hello maddin,

UV parametrtzation for single camera option of spherical images will be fixed in the next update.

OK, great! Thank you!
