I've recently upgraded from Poser 4 to 6, and am having a few problems. I created some textures and bump maps for V3, and they worked perfectly in Poser 4. When I come to apply them in Poser 6, a strange thing happens. Have a look at the pic; the dark markings around the eyes, across the bridge of the nose, around the mouth, and in the ears, are not on the texture map or the bump map. This is a Firefly render; when I try and render in the Poser 4 mode, the markings are still there, only strangely the colour of them is inverted from dark to light. Does anyone know why this is happening, and what I can do about it?

i would guess at ambient occlussion check your lights properties and fiddle with the ao or turn it off altogether.

It looks like the bump maps are too strong, if you make the strength of the bump maps a much lower number they should work ok.

Ambient is set to zero. The bump maps are currently set to 10%; I'll try it lower and see what happens. But I did like the effect of a strong bump map. I don't understand why it's only happening in these areas and not all over though.

The body has the effect as well.

I had this problem with several textures and had to experiment with the 'min displacement bounds' settings. Generally, they seemed to settle for a setting between 0.02 and 0.03.

I've also found that with most textures, it's better to set Firefly to Manual settings - I start with the above, and alter as necessary. I have 1.5 gig of RAM, so a bucket size of 64 is kewl; machines with less RAM may want it set to 32.

Hope that helps

Is your Bump map a .jpeg image or is it a .bum image that Poser 4 uses?
I have noticed that sometimes if you use the Poser 4 .bum image as a bump map in Poser 6 or 5 it looks similar to this. If your bump map is a .bum image, try just using the bump .jpeg image instead and see if it still gives you the same result.
I hope what I wrote makes senses... :)

Poser 6 renders bump/displacement settings with much more 'force' than P5 did; trying lower settings is a good idea. For human skin, I end up with settings in the .0025 range, but "your results may vary". The blacking appears to be due to a too-high setting on the ambient occlusion bias (either in the lighting or a material node).

Thanks for all these suggestions; I'll try them out in turn and let you know what happens. The bump maps are jpegs though. The ambient occlusion; is it the same as the Ambient dials, as I can't see any controls with the word 'occlusion' on them?
