Feather Texturing

Recommended Posts

  • Topic Author
  • I've created a plane and in photoshop i've created a feather.

    i've saved the texture as tiff, transparent png, and so on.

    I've created a new material and set the image as color material.

    then used the same image for alpha.

    It become transparent background but around the feather border compare a grey line and i can't remove it.

    Please help me to use transparent texture.

    Some tutorial or advise is good!

    tnx

    Is your alpha image a true black and white with no greys at all?

    I'm pretty sure you need to work on pixel level to get the alpha straight. If you set your render settings to "straight alpha" does that change anything?

    If not, than it's the PNG

    You may need to start again then. In photoshop make the feather colour channel on a layer. When you're happy with it hold control and click on the layers thumbnail to select it's pixels. Make a new layer and fill the selection with white. Inverse the selection and fill with black. Now save the layers out as JPEG's for a colour, and alpha channel. smile.gif

    arhmm? waT?! just render out the image with alpha channel turned on in the save settings. Everything else leave default. Make sure to render against a black background. Then just use that as your alpha and diffuse. The image might be bigger physically but all you have to do is save out the alpha channel from PS if yu want flattend jpgs. I always prefer a single file for diffuse and alpha. But if yu intend to use a lot of textures or objects using this texture then go jpg.

    Color channel = colored jpeg or png or tiff or psd.

    Alpha channel = Black and White (Black transparent, White opaque). If you get a visible line around your image, increase the black by a pixel to mask more.
