dynamic NailLength in poser

Theres an old trick in poser to dynamically change nail length and Dimesnsion3d taught me it.

"U OFFSET = Nail length * -0.0489
U SCALE = (Nail length*0.065) + 1"

How can I do this in photoshop so that I nudge these "units" in Photoshop? Or can we achieve it in Octane? Right now the result is unmatched length.

Hi - interesting approach. I would have thought this would give an odd result because whilst the nail texturemap is being increased/decreased in size, the underlying geometry is not. So I think using a nail longer/shorter morph would be a better solution. Regardless, you can tweak the U OFFSET via the Image node->UV Transform->Translation (probably X, but might be Y), and the U SCALE via the Image node->UV Transform->Scale (probably X, but might be Y).

Agree with Paul, it sounds like an old way of doing it. I'm pretty sure morphs++ has a nail length morph.

To both of you

When fingernails grow, they simply arent scaling logner and longer
Your pink part remains and the white part lengthens.
To manage something like that you stretch the map lengthwise and then jut it backwards so that
overall the pink part and white part get longer, but you shift the pink part into the nail by offset
so that it lengthens the white part which accordingly matches up with the nailslength morph, its a dual-involvement going on, the bitmap needs to change, and the morph makes the geometry change,

And i was saying in poser you use mathematics in nodes to do the formula which will always be dependent of NailsLength's value as a variable, and I cannot seem to reproduce this effect in octane

I cannot.

Adjust with the X Transform of the UV Transform of the Diffuse texturemap of the Fingernails material.

Does that make both hands work? Offsetting material may offset nail in one direction but the texture map manages both hands and that means an unintentional sliding recession in the other hand.

What I need is an offset+scale combination. Will offset nails to left hand advantage but will STRETCH to accomodate that missing space at the other end of the jpg file that stretches to the other end of the skin map for the right hand. Without doing this and only offsetting will cause parts of the skin map not intended to be shown to be shown on those regions of the fingernails.

You are right - my apologies. Pls see the complete formula here...http://render.otoy.com/manuals/Poser/?page_id=390
