Creating the Draper Fretsaw from photogrammetry and sub-d modelling
My first project! Has been quite a challenge so far but finally seeing the light! Not shared anything on this project yet - so I'm intrigued to see if anyone has an interest in this? I will be updating this as I get closer to finishing it so... I will be back!

Recreating Draper Fretsaw
A large project (for me) with the intent to composite the 3d asset into a live action plate as part of a showreel.
This project began with a few attempts at photogrammetry for the base model, to get an idea of scale and proportions, and ideally some textures. As most things go none of the photogrammetry really went to plan and meshroom really struggled to create a model based on the hundreds of images I used. The first image was the first attempt and the second image the second attempt. Not the best but gave a decent idea of what I was aiming for, and I could possibly extract a few areas for use in the texturing process.
Modelling all the components of the saw was a slight pain just due to the amount of time it took, but the UV's took quite some time on their own. So many little details meant almost overlapping vertices that of course all had to be spread out a bit more evenly to improve overall texel density.
Blender's current UV tools aren't the greatest so had a go with a few free plugins to help organise and reduce the workload a bit. Still plenty of manual labour as blender's current UV packer (or even the plugins) don't seem to be able to pack across multiple tiles, and if they do manage it, then it's a really poor and inefficient job, especially not maintaining scale during packing so texel density continuity is almost impossible. For the most part I used a plugin to scale the individual islands to the correct texel density, and then manually packed all the islands, which was very slow work for 12 UDIM tiles.
I'm currently texturing the finished model in substance painter and will update this post when I have anything worth sharing. Thanks for looking at my first post!
