Does it support .png ? ... can't find out..have and a brief look but no info that I can see..sorry if it does already and I missed it Smile

The alpha in .png is a handy thing to support...

No PNG at the moment. PRO does support TGA though. Smile

Cool..TGA is a good start and a firm fav Smile

I'm very fond of PNG with it's inate alpha solution...means no seperate alpha layer or faffing around with greyscale, if it's transparant on the texture...it's transparant in the game.

You may want to look into this Smile

Would it be difficult for you to extend the plugin architecture to support custom image loading formats? One method I can think of would be to have the plugin send an enumerated list of what images it found and supports and then have deled request the file data as a raw rgba buffer.

Hmmm, I think I like that idea. One of the reason that DeleD doesn't support 10.000 file formats out of the box is that we usually are not too fond of using large chunks of 3rd party code inside our application (nor do we really enjoy the type of license that usually accompanies image loading libraries)...

Opening the image loading up through plugins would effectively solve that problem!

That said, we plan to have PNG support as part of the DeleD core anyway.

PNG will be worked on after the Torque exporter is completed.

For image loader plugins: I'd recommend having them return BGRA format pixels, which is the fastest native internal image format. If you don't want to hard-wire that, then provide a way to tell what's there (BGRA/RGBA/BGR/RGB/A).

Is this still going to happen? This is the only thing holding me back from buying the pro version. I must have .png for my mmo project. I hope this is in before the end of the year or I’ll need to spend the money on a different level editor that has .png support.

Yes, DeleD 1.5 PRO will have PNG support. It will be released within two weeks. Smile

I prefer TGA over PNG, because with TGA I know exactly what I get. With PNG, the embedded gamma is actually treated differently by different programs (and libraries), so the path Photoshop -> Tool -> Exporter -> My Game is a lot more transparent (pardon the pun) with TGA.

For the final product, you'll probably be using DXT5 anyway -- can't beat the bandwidth savings (or resolution doubling)!

That’s strange, because PNG has color management while TGA does not. I prefer PNG because it’s lossless, can be used for alpha channeling, handles color management and has no patent.

Yes; that's what screws it up. (!)

Textures are mathematical data tables, not photographic images. I want my data un-modified when I load it into a game.

The relatively "good" news is that DeleD's PNG support utterly ignores any color mangement info when loading images Very Happy
