This is an update on my behalf regarding my helmet project. I used baby powder shaken on my photographic subject and blew away the residu, making features this way. I made about 900 pictures in 5 loops in an amateur studio setting. Using two lamps and the subject placed in a white tent. I used a homemade rotating plateau, for 360 degrees imagery. Images came out ok, could always be better. Still some flash on the object surface. I run an alignment and got a large component, about 850 images or so. Not bad.
Because I was not very satisfied with the quality of the pictures, I decided to take some new another day. This time I tried outside in daylight in the white tent, but I cleared the baby powder of the subject so the original surface appeared. Smooth grey semi gloss single color. I took another 900 pictures en run RC alignment again. I got 45 components and my biggest one was 125.
could this really be the baby powder making features for better alignment?

You basically proved it! 
So yes, very likely.
It would help if you uploaded a sample image though…
I think this tutorial covers this topic very well, i’am am also interested into your results with and without powder.

@Götz Do you now if RC has a “show your projects” board, or it’s planed? I really would like to share my results in this forum, but the “General Discussion” board is not the right place for it, i think.
Tom, I thought you are a non-social-networker? Did I lose you to the crowd?
Anyway, tingelbobber, afraid not - there is only what you can see.
We’ve suggested something like that ages ago but nothing happened.
I would just do it in General Discussion - there are quite a few lengthy threads where people were comparing results. So why not add yours?
I’m curious…
Oh, a closed facebook group. I have no FB account, so i wasn’t aware of it.
Strange, my username has also changed here
Ah, also one of us?
I’ve heard several times that at FB it’s more basic stuff and hey-look-what-I-did sort of posts.
It’s supposed to be just that but in fact is technically as high level as here, with answers from RC people. Valuable.
No I’m def not SM (that means Social Media BTW) but have FB, Twitter, LI a/cs, never visited except the RC one.
Another update today. I took new pictures again, in the same outside setting, white tent, rotating plateau etc. I sprayed baby powder on my object again an began taking pictures, creating 360 degrees photo loops from different angles and heights. I created 9 loops with the whole object visible and some closeup photos for details. I uploaded every loop individually in RC and got perfect alignments. 9 perfect loops, unfortunately I use the demo and can not merge components.
The only problem I got, was with the individual closeups, which were taken random on the details. These were the only photos which did not align properly. But I got to understand why! They were not taken in 360 loops. I took some new closeups, but this time in total 360 degrees loops, overseeing the detail. I created 5 closeup loops and again uploaded them individually in RC. Yet again all loops with perfect alignment!
Now for the challenge. I have uploaded all images (with all loops including closeup loops) with a total of 1783 images and I am running alignment at this moment. I will have to see the outcome of this, so fingers crossed.

Probably your non-loop scattered detail shots would align properly in an ‘all images’ run.
And you can also transition slowly from your loops to the detail and then back again at a different spot of the loop or a different one…
