This one's kinda peculiar.
Just to prove I aten't dead, and I really am working on the next release of PPP, here's something funny I came across while playing with bump maps:
I've attached two character XML files. They're basically identical copies of the original "robyn" file[1] except for one difference: I've altered the "b" file to attempt to use layla's bump map.
Whoops. It doesn't like that at all - she's developed a rather severe case of albinism (screenshot attached - the body texture is gone, and she's rendered as white - really white, as in #ffffff-white for all you hex-fluent people).
If I swap it out to use a custom texture, rather than an original one, the body texture shows as normal, but mis-matched original body texture and original bump map: white as the driven snow.
Is it meant to do that? I appreciate that doing mix-and-match with textures and bump maps may yield peculiar results, but I regard that as half the fun of playing with randomness.
[1] I tweaked the name and the "image" element, so they play nice in the user_created directory, but I'm fairly sure that's not relevant here.
