Thanks for the advice, i know how to save png files but its super png am talking about, i was thinking when i make a save if i am using a png image with transparency and no alpha channel in the channels section it will automatically create an alpha channel for me so when i open it in photoshop i would see that extra layer…
For Photoshop to export a transparent PNG the transparency needs to be in the layer itself (as transparent pixels), not as an alpha channel in the Channels tab. This means you should see a checkered background for the transparent parts. If you only have transparency as an alpha channel and you want to make a PNG, you need…
well for speedtree i have to save as 32 bits to keep the alpha part of it but i think for this project i am on the programmer will tell me what he prefers, i refered him to super png so lets see what is best before i start working on textures
SuperPNG has control over the transparency/alpha of PNG on both load and save. You can tell it to treat the alpha channel as transparency or as alpha (the difference being that if it's transparency then all the pixels that are fully transparent have their colour optimised out for compression, so probably not the result…
SuperPNG doesn't change the PNG format specifications, it just saves files more efficiently than the default Photoshop implementation with a few more available options. PNGs do not support multiple layers. (So all that said ... you are now seeing why many people like to use TGAs. In practice it might not sound like a big…
"the programmer will tell me what he prefers" Make sure to fully test all the variables of the solution you end up going for, as this stuff goes much deeper than just "transparent or not". For instance in some circumstances you can end up with the transparent pixels being effectively deleted, which might not sound like a…
