Photoshop and PNG problems - FIXED!

by Jarrod Roberson · in Technical Issues · 06/14/2002 (9:53 pm) · 15 replies

photoshop does not seem to like PNG files with an alpha channel that is used for reflection mapping in Torque.

Crappy default PNG reader that comes with PhotoShop 6/7 looks like this

I did a tiny bit of research and found this . . .

SuperPNG

so with it you get this

be sure and delete the original png.8bi file from photoshop or it.
Quote:Important: It is highly recommended that you remove or disable the standard Adobe PNG plug-in and use SuperPNG in its place. After Effects on the Mac OS will probably behave strangely with both plug-ins installed. Windows users will almost certainly experience problems in both Photoshop and After Effects if they run both.

Nice, but, does this also fix the png alpha channel exporting problems that photoshop presented too?

mmm... I enter the "Photoshop 6.0\Plug-Ins\Adobe Photoshop Only\File Formats" Directory and deleted the png.8bi there. Then i copied the SuperPNG.8bi in this same directory and renamed the file to png.8bi
Now i tried to open player.png (the default torque player skin) and it says it can't open it due to a problem with the import-export plugin

What's wrong?

Also it doesnt seem to add transparency, I made a new transparent image, added a layer, drawed a line in the new layer, saved as png, but when i opened the png again the background was white

I was getting errors when I copied the whole directory into my plugins folder.. when I moved the SuperPNG.8bi out of its own folder, things worked fine.

follow the instructions in the release notes . . . RTFM :)

it goes it the regular plugins \ file formats directory.

remove/the stock one

Works fine for me.

Jarrod, is it supposed to run on Windows, too?
If I replace the default Png.8bi with any of the files in the download (renaming them to the same name, of course), Photoshop 6.0 doesn't recognize PNGs at all any more... so I can't open or write them...

where in the instructions does it say to rename anything?

Does everyone try to make things WAYYYYY more complicated than they really are.

Release Notes

Of course you have to download the Windows version for it to work in windows.

I had ZERO problems with it so far.

See my screen shots, they are from XP

Sorry, didn't see the little radio button while downloading... and Xavier wrote something of renaming it to Png.8bi ...
I'll give it another try... :-)

Still wont work for me...

All I did to get mine to work was place it Photoshop/Plug-Ins/File Formats

I left the built in png file alone.
This worked for me and I can do both if I want to. SuperPNG shows up just like SuperPNG (*.png)

well it works mostly for me, but i still can't open the player.png from the torque player model... keeps saying it can't open it due to a program error

Yeah, I'm at the same point now as Xavier... I've removed the old PNG plugin and put the SuperPNG in, but if I try to open any PNG it reports a program/pugin error (on Photoshop 6.0 German version, Win2k)...
