Hi!

 I was wondering if it's possible to have a MAT pose that loads a texture on top of a figure via the pose library? So that I can load it over top of the character's actual skin texture.

 For example I want to have claw marks that I can load onto M4, and have it overlay on top of his skin. I want it to work any any character, one-click solution.. no having to go in and alter anything in the material room.

 Any info would really be helpful. :) A tutorial, a link to a product that does this so I can learn, etc.

 Thanks!!

Attached Link: BB's VSS

A product that does the Python script is BagginsBill's VSS. It has a prop with 'most' of the shader, then the Python script adds that shader to your figure, plugging in whatever main textures you already have loaded.

That would be the way to go, as BR posted.  Unfortunately, you would need to work out the node arrangement to add the additional image map. 

Well you could use a blender node and a mask to do that once.
Then save as a material???
Depends on your workflow.

A python script for that is readily available if you want it.  It just unhooks the diffuse channel and adds a blender node and image map and mask.

Link? Cuz I think I'd even be interested in having that handy little script.

 Oh, I didn't realize it'd take scripting, which I have no idea how to do, lol.

 The thing is I'm doing this as a product to sell in the store, for others to apply, so unless I can distribute that script, I'll just forget it and include the photoshop layers along with a tutorial on how to apply it to your own textures and how to postwork it too. Much less convenient, but what can ya do.

You wouldn't ahve to do much more than edit the script and adjust it to your needs.

And, if you're able to contact whoever wrote the script, they may have no problem with you including it with your product, as it's just there to help out, and it's not the main thing you're selling.

BB is that way with his shaders, you can have them part of your pack, they just can't be the main thing your selling.

I wrote the script, I just have to find it. :)

Oh, so would you allow Xameva to include a modifed version in the product? I'm positive it's the best way to go.

SnarlyGribbly wrote me a few scripts for my bicycle, and one is included. It brings up a color palette so the person can choose any color they want that's not included in the 90 MATs included. Extremely handy those little scripts can be.

...And btw... May I get it too when ya locate it? I would be most obliged :o)

 I'm sure it could help a lot of content creators. For example someone is selling a sword prop, and as a bonus there's a MAT pose to load a flesh wound onto their character.

 I'm assuming DAZ users would be out of luck though?

find node attached to diffuse and disconnect

add image map x 2

add blender node

connect all

import poser, string

image files

myimg = ":Runtime:Textures:myimgs:myimg.jpg"
mymask = ":Runtime:Textures:myimgs:mymask.jpg"

fig = poser.Scene().CurrentFigure()
mat = fig.Material("2_SkinTorso")

nod = mat.ShaderTree().NodeByInternalName("PoserSurface")
inp = nod.InputByInternalName("Diffuse_Color")
mynode = inp.InNode()
if mynode:
    inp.Disconnect()

create nodes

blend

blndnode = mat.ShaderTree().CreateNode(poser.kNodeTypeCodeBLENDER)
blndnode.SetName("Overlay Blender")
blndnode.SetPreviewCollapsed(0)
blndnode.SetInputsCollapsed(1)
blndnode.SetLocation(231,80)
inpdif = blndnode.Input(0)
inpimg = blndnode.Input(1)
inpmask = blndnode.Input(2)
blndnode.Input(2).SetFloat(1)

overlay image

imgnode = mat.ShaderTree().CreateNode(poser.kNodeTypeCodeIMAGEMAP)
imgnode.SetName("Overlay Image")
imgnode.SetPreviewCollapsed(0)
imgnode.SetInputsCollapsed(1)
imgnode.SetLocation(231,111)
#imgnode.Input(0).SetString(myimg) # remove comment to enable <<<<<<<<<<<<<

overlay mask

masknode = mat.ShaderTree().CreateNode(poser.kNodeTypeCodeIMAGEMAP)
masknode.SetName("Overlay Mask")
masknode.SetPreviewCollapsed(0)
masknode.SetInputsCollapsed(1)
masknode.SetLocation(231,141)
#masknode.Input(0).SetString(mymask) # remove comment to enable <<<<<<<<<<<<<

connect

mynode.ConnectToInput(inpdif)   # connect diffuse map original to blender
imgnode.ConnectToInput(inpimg)  # connect overlay map  to blender
masknode.ConnectToInput(inpmask) # connect mask to blender
blndnode.ConnectToInput(inp)     # connect blender to diffuse

update preview and redraw scene

mat.ShaderTree().UpdatePreview()
poser.Scene().DrawAll()

it finds and detaches the node plugged into Diffuse color

creates a blender and two image nodes

myimg is the overlay image

mymask is the overlay mask

plugs the node from the diffuse color into blender

plugs the blender node into diffuse color

this may not be all thats needed but should be close

I may have to unplug and attach blender to specular as well  ?

This is hardcoded to overlay onto 2_SkinTorso material  , that is what I need to know or I can make it current selected material .

the script needs some changes , uncomment the two lines that set the image names , and edit the script to use the proper image names rather than my test names

rename it to a .py extension and put in the poser python folder. run from file menu.

Oh, yes , Daz Studio wont run a python script.

A daz version might be possible but not by me :)

And Yes , I could be convinced to allow distribution.  

I'm a complete novice with the scripting/material room, but I'll give it a try. That's awesome, thanks!!

Convinced eh? Should I send you a gift basket with chocolates? :) Or.. will written credit in the description and readme and the product for free be good? Or something else, let me know here or PM! :) 

Thank you for the script!

Would it be hard to make this script for whatever material is seleted? That would make it more useful on other figures/props as well.

I'm a Poser user, so it's most useful to me :o)

You can do it with free Advanced shader by Semidieu

http://www.runtimedna.com/Advanced-Shaders.html

with it you can create a script that will load the overlay on every texture you want.

 That is absolutely awesome, thanks for the link ima70. Makes things much easier!!!

just change mat = fig.Material("2_SkinTorso")

to

mat = poser.Scene().CurrentMaterial()

Thanks markschum, the script is very handy. Is there also a way to set the scale and offset for the overlay images, and make them 'Clamped'?

What I'm trying to do is add a tattoo, and I would need the the nodes set up as in the above image. Can you tell me if it is possible to modify your script to do that please?

for DS users you can use the LIE,

i'm not sure how it works, but I've seen wound and blood packs that use it.

oh, wait, i see one for poser, too.

:b_drool:

@les, yes of course. The crude way is to count inputs from the top

so in my script imgnode.Input(2).SetFloat(x) will set U_scale

ingnode.Input(7) is the clamped parameter and thats where you screw around to see what the settings are.

You can of course get the input by node.InputByInternalName("name")  and thats better for documenting code but you have to recurse the node to get the internal names. 

Look at Poser python methods manual ,Shader node and shader node input sections.

You probably want to duplicate this bit

np = nod.InputByInternalName("Diffuse_Color")
mynode = inp.InNode()
if mynode:
    inp.Disconnect()

for specular

nps = nod.InputByInternalName("Specular_Color")
mynodes = inp.InNode()
if mynodes:
    inp.Disconnect()

and then connect the blend node to specular.  I will change those and repost the script later tonight

Quote - I will change those and repost the script later tonight

Thanks markschum, that would be a great help.

I have renamed the script to set_image_overlay.py

I have made the specular connect only if it was connected 

the code to set the image nodes are commented out  so remove the # to enable them

after setting the values and filenames

I added a comment line for setting the clamped or tiled setting , its not well documented and for reasons unknown they did not use 0 .

Thanks to Philc for pointing out in his book that the hide preview setting is wrong in the Poser methods manual.

I have commented some things to try to explain whats going on.
