I have a transparent .png image I would like to use in Poser 11.3 is it possible to map it on to a plane to it can be posed? Thanks

Poser will only interpret black and white transparency maps, not alpha channels.

If you have a png file where the transparent parts are, well, transparent take the file into an image editor, create a black fill layer underneath, merge down, flatten image, and save. Black is transparent in Poser. White opaque. Half tones degrees of transparency. If it's a color image with an alpha channel merge it with an opaque layer and apply that as you would a color texture. Take a copy of that file, select the outline of the color information and fill that area with white (opaque) and the background as black and use as a trans map. UV map your object, and fit the image to the UV Template. You will have 2 files, the color diffuse and the black and white trans. Apply as you would a regular texture in the material room with an image map node attached to the transparency socket, when you load the transmap change the gamma to custom 1, black and white maps such as bump, spec maps, displacement, and transparency must be custom gamma 1. Apply the color version as you would a diffuse texture map.

If you need further images showing how to make the 2 maps let me know, I'll whip something up real quick.

FYI: Poser 12 does recognize the PNG alpha channel in Superfly on the PrincipledDsfd node. To generalize that it doesn't is misinformation. It definitely doesn't exist in P11, I checked.

Wasn't aware of that hborre, Sorry for the misinformation, which sounds so ominous when you put it like that lol. Thanks for the heads up.

Anyway here's how to do it in 11 as per OP's thread title and query...

So I downloaded a leaf image in png format with a transparent background...

For the Diffuse map I import it into my image editor and create a sympathetically colored background fill layer. I do this to minimize fringing. This particular png already has a bit of fringing I see, I'll just leave it for the demo. I merge down, flattening the image and save as leafDiffuse png...

I then take the same image, create a black fill layer underneath, select the colored portion of the leaf png and fill with white. You can blur the edges of the white fill a bit to give it a softer edge in Poser transparency. I flatten the image and save as leafTrans png...

Back in Poser I load the one sided square primitive from props library. This prop is a single polygon thats uv mapped. In order to match the aspect ratio of my image I scale up the square to x1000 y2000. I then scale down the overall scale to 25%, the square is now ready to apply my maps...

I go into the advanced material room and apply my maps, making sure the trans map is Gamma 1. You could also create a bump map in an image editor by desaturating and tweaking the color image or by using an HSV node in the mat room. You'll have to experiment with the specular, as it loads the diffuse will be washed out from the specular...

Works in Poser 11. http://www.jurn.org/dazposer/?p=14317

Nice one. I'm surprised I've never seen it since it's been around for so long.

Guess HartyBart isn't the conversational type lol.

That's amazing !!

How does it all compare to trad method of saving out the whatsit.PNG's Alpha channel in eg free Irfan View, applying this whatsit_T. JPG as transparency mask in 'simple' materials ??
