alpha textures on Flickr


Mera asked a really good question about alpha textures and downloading them from Flickr (this is an impromptu part 2 of yesterday’s post about using Flickr to host your virtual world textures)

it’s a little tricky but easy to grab the proper version that retains its alpha goodness. remember that all files uploaded to Flickr get turned in jpgs and are automatically sized to several sizes. none of those will work since they are jpgs and jpgs don’t support an alpha channel (bad, jpg, bad!) =p

you have to have a paid “pro” account so that you can access the original file ($24.95 per year USD). i know that is true for your own originals and assume that is true for trying to download someone else’s original. if you want others to be able to download your originals, make sure to set their permissions properly

log into Flickr and go to your image and then click Actions and select View all sizes and then Download the Original size of this photo

alphaTest_png8Alphaonly the original one is the actual exact file you uploaded. in my testing i uploaded an original work png file complete with its layers and then also exported it as a gif and png-8 with alpha transparency (not index), and as a png-32 (natively transparent). i then downloaded those files from Flickr, which are renamed by Flickr, so maybe keep that in mind as you download them. i just paste the Flickr picture name in the save dialogue box and that way the name is meaningful and not something like 6842576795_4ccefd7dfe_o.gif

all the downloaded files retained their alpha information and the original layered file kept its layers and was fully editable (score! i did not know that!). since the original work files stay editable, it might make sense to also store your work files on Flickr. that way you can make edits to them even when you’re travelling!
*bah, who needs a vacation!* =D

here’s the test set on flickr

the files can look ugly, like no alpha on the black bars, but they'll download fine

only the original image holds the alpha information

  4. […] swapped out 18 textures (freely available here but download them as originals which was discussed here) and have only done so on 4 regions but is the time i’m spending doing this going to pay off? […]
