I’m much more of the conveyer belt approach. It’s definitely faster, but you need the right mindset for it, as painting up to 24 of the same figure in one go requires a good deal of mental fortitude 😮😉
Batch for me. The 6mm stuff you really need to do batches but I even try to do batches in 28mm. I usually struggle to make a group have some variance in colour whilst not looking like harlequins.
Painting I find a real chore I am afraid.
I had the same problem but my Dad told me to use mainly two primary colours in a unit. Apparently it's best to use complementary colours eg blue and yellow and red and green. You can use different shades of these colours and muted shades of secondary colours to give variation.😀
I always start batch painting - generally a complete army of 40-50 figures. But after the base coat and block painting the basic colours. However, as I go along I reduce into smaller groups of 8-10. By the time I’m doing the detail and touching up I’m painting individuals. I find this is the fastest method of painting figures.
Batch every time, for me...mass production. I also, in this process, try to paint the figures who are in the same pose at the same time, so I can remember to do all the same belts/ quivers / rpgs or whatever. Less chance of suddenly finding one unpainted later in the process (especially as I often mix colours as I go, and remixing the same colour is hit-n-miss).
I've always batch painted. But think I'm going to go by stand for next project. I'm painting two armies: Samurai then Ming. I don't think I have the patience to do individual figures, but this may be a good compromise.
Like Paddy649, I start with doing blacklining, grass-green, flesh, etc, then go to finishing up individual figures.
It may be noted that we're holding this discussion in The Age of Acrylics (IMHO, acrylic paints are one of the five greatest improvements of my lifetime). In the Good Old Days of enamel paints, which took hours to dry, batch painting was a necessity. Also good ventilation.
I used to paint in batches when I was doing up 1/72 figs. for a War of 1812 campaign, and at times found it one heck of a chore.
I now paint one fig. at a time, and enjoy the experience far more.
I've tried both over the years & found that painting in limited batches suits me best. I choose maybe 5 or 6 elements (usually needed for a particular list or options & try to blitz them before getting hung up on the next obsession. Still have an Everest of unpainted figures though so maybe I'm still doin' something wrong...
