.png textures not recognized by AC3D

I haven't received a file though email.

You are using AC3D 8.0 and I suspect that your PNG file would work on the latest AC3D 8.6 since a lot of work was done on file format support for the 64 bit AC3D 8.3 release http://www.inivis.com/ac3d83.html

should be gone now, using gmail instead of pm.

Thanks, the image works fine in the most recent AC3D.

The PNG may be using an alternate method for storing alpha, or some other format update. The PNG importer was enhanced in AC3D 8.3.

AC3D can not handle .png textures, i understand.

thanks.

Sorry - you are not understanding. This is a summary:

Your PNG file has new features not supported in your 2016 AC3D 8.0
The latest AC3D 8.6 supports these newer PNG files.

If you want to use that PNG with AC3D 8, you will need to convert the PNG to an older PNG format.

I have converted it for you here:

If you are determined to not upgrade AC3D, you will need to do this yourself for all PNG files you use.

wasn't aware .png's had version updates later than 2003 (ISO/IEC 15948:2004 certificated version),
it represents a universal format used worldwide, especially on the net.

It works anyhwere else, for some reason it doesn't in AC3D.

i found out that creating .png's in Corel seems the source of the problem. Some sort of file definition must lead into a variant of png that makes it impossible
for AC3D to show it on the 3d-model.

Part of the solution (for me) is to re-open the finished .png in other paint programs, like paint.net (freeware) and save it again, let paint.net do automatic
recognition of file format settings. From now on, the textures do show in AC3D.

Another issue is that parts of the model would not show textures when running x-plane, despite everything looks fine in AC3D.
I havn't found a solution for this specific issue yet.
