new to meshroom: cant seem to get a finished render please help

[avgdragon]

So I made a diffuse box and got my camera set up pointed at a turntable to takea bunch of pictures. At first I kept getting an error that stopped at StructureFromMotion every time I tried to Comupte. I dont know if its not enough pictures or maybe Im not using the Pipeline correctly? Heres a google drive of all the pictures I took

After taking more pictures from more angles it finally did finish computing but only 5 out of the 32 pictures were used giving me only one side of the mesh. Any advice to really get started would be appriciated.

As far as I can see from the images your subject doesn't have enough surface texture (no color variation just plain black) which is probably causing the lack of camera aligments.

If you're able to I suggest you use a chalk spray paint (it can be washed off after scanning) to add texture details.

days of tweaking my set up and i have finally gotten a decent scan. i think the big issue starting out was that my background had too many features so meshroom couldnt see anything turning. that and not enough angles and bad lighting.
the no features thing i think was true as well and i dont know if it helped but i put a bunch of sharpie dots on a clay figure i made i made to scan and i got a must crisper 360 result. some people say though that the dots dont make a difference which i dont understrand.
I wish i knew what the errors meant

Oh well another thing I noticed now that you mentioned the background it seems as if you rotated your subject but still showed some part of the background? When you do photogrammetry you should act as if the world is frozen and nothing moves (or at least the software musn't detect the movement) except for the camera. If you're doing a turntable scan make sure that the whole background is featureless (pure single color background and you can even create masks).

Covering a object with no features using a shrapie does indeed make a posiotive difference imo. I tape the subject with painters tape (easily removable) and then go wild with a sharpie and draw random points and lines on it.
