Hi,
I already checked previous posts so I know it's something other people found before. Using a bump map on a model in Poser 6 or 7 (I didn't check if it's the same for P5; for sure it wasn't in P4PP..) takes a very strange (and very annoying) effect: besides the desired bump effect you were actually looking for, carefully setting your bumpmap, you get a bonus: a light (but clearly evident) bump-effect that renders the mesh structure of the model. It happens both in Firefly and P4 rendering. At first I thought I forgot a "template layer" on my bumpmap, but in the end it looks like the effect is "mesh based" and comes out whenever you use a bump map. Well, as I alredy told, I'm not the first one to experience it, but did anyone succeed in solving it? Since it's present both in P6 and P7 it looks like e-frontier (or Curious Labs or whoever is the actual owner of P...) didn't notice it? Is there an update to solve the problem? I admit I didn't read all the posts about it, but I don't consider "solving the problem" setting the bump values to 0,00...; the mesh structure sure disappears... along with the bump effect you were looking for! Thanks to everyone who will have the patience to help,
Alberto

post screen cap of bad bump/mesh interaction, along with screen cap of materials room
settings. ISTR there was something about using gradient bump, or else just drop bump
and use displacement channel.

OK, I'll try with displacement. Thanks

Last I heard, bagginsbill had filed a bug report with Sith Micro - so there may be a fix sometime around Poser 9 or 10... :)
If you're using a map which uses mid-grey to represent "no bump", as Poser 4 bump maps did, you'll get this effect. You can use a math node to subtract 0.5 from the bump map, which will return the mid-point to zero. It helps on some maps, but won't be 100% effective on them all.

Thanks, I'll try that, too.

I did post a bug, and they did fix it.
You want Poser 7 SR3.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)

Kudos to SM, in that case. I retract my previous allegations of sloth. :-)

Thanks to everybody!!!
