Topic awaiting preservation: POV-Ray: how to use an image as a texture (Page 1 of 1)

ok, i've got my object there in povray, and the texture should be a pic i created in PS.

i tried to do so with texture_map, but somehow it wont work out.

anyone know some other attempt to do this? slime?

IF you want to take the actual color of the image as the texture, do this:

texture {
pigment {
image_map {
tga "myimage.tga"
once // optional
interpolate 2 // optional, but use it if the image can be seen from nearby
}
}
}

If you want to use a greyscale version of the image as a pattern, that can be a bit tougher.

ok, thanks slime. it works, but it wasnt actually what i wanted, cause the image gets scaled all over the object.

but i think i could solve my problem if there's a possibility to place a picture somewhere in my scene. is it possible?
and can i use transparency? i tried it with my gif, but it uses the matte color to fill the rest.

First, use they keyword "once" to keep the image from being repeated (unless you *want* it to be repeated). Then, scale, rotate, and translate the texture as necessary to make it the size you want it to be.

For transparency? Well... that's weird, you can use the transmit keyword inside the image_map, with an integer after it specifying the color entry of the gif to use for transparency. Personally, if i want transparency, I just use like a PNG or TGA or something like that.

yepp. it worked! thanks so much slime!

im using png now. but it seems as if the pic gets colored depending on the object-color. as if the pic has a opacity of 70%... this looks kinda strange, cause im using a photo. is there a way to avoid this?

edit: i solved the problem by alternating the opacity in PS

Sounds like a problem with your PNG...
