    Ace to TGA loses transparency

    I'm working on a repaint of Tim Blythman's Melbourne tram. In fact, I thought I was done, but the transparency disappeared.

    I think the problem is in the Route-Riter conversion of Ace to TGA. When I used it and then used Ace-It to create a new Ace, the transparency had turned into dark gray.

    When I opened the TGA in Gimp 2.8, the gray checkerboard was there and it had an alpha channel, but no transparency as an Ace.

    Route-Riter had no options in the graphics conversion, so there are no settings there to change, at least that I can see.

    Any ideas as to what I should do differently?

    Thank you.

    If you have AceIt it might work better.
    It has the option to save with alpha.

      Thank you. I tried converting the Ace file to TGA using Ace-It, and it created a file but then couldn't read it. I have TGA tool 2 but couldn't figure out how to use it for converting Ace to TGA, but I found a Steam4Me tutorial on how to do it, so I'll try that. I also found a program called reaConverter for batch conversions that is for sale, but the website has free conversion online for just a few files, which is all I need. I used to be pretty handy with Photoshop at work, but that was 6 years ago, and I don't have Photoshop now. I found a Gimp manual on the Gimp website with a warning that it has errors and missing pieces, but I will look at it. So I have a few things to try …

        If you are using OpenRails you could just save it as a .dds.
        I think Gimp will do that natively.

            That's what I use but he is already invested in Gimp.
            Way to confusing to me.
            Paint.net is great. Once you sort through the plugins.

              Gimp is free, and one of my kids downloaded it years ago. :-) All of them are grown and far away now.

              I was using Paint.net, but the TGAs it made lost the transparency.

              My computers can't handle Open Rails.

              The Steam4Me tutorial for TGAtool2 said to read the manual. >

              I found and downloaded a TGAtool2 installer, which gave me the manual. I already had TGAtool2 but no instructions that I could find. I just worked on one of the Aces using it, with Paint.net as the image editor, exported the Ace from TGAtool2 and tried the result in the simulator. Transparent windshield, yes!

                Glad you got it sorted out.
                I've found that the best tool to convert .aces to workable images is Shapeviewer.
                It exports the alphas along with everything else.
                Tga tool will only export either the alpha or the image w/o alpha. It can be a pain to get the two together.

                  I have Shape Viewer, but I didn't know it could export graphic. Well, when somebody else is losing transparency in images extracted from Aces, this thread will have a lot of answers. :-)

                    The new Shapeviewer that came out a few years ago that will handle .dds textures is especially handy.

                      Unless I misunderstand the problem....the easiest thing to do is open an .ace file in TGATool2, then click "file" and "save as" to save the image as a tga. That will maintain the alpha as part of the image for editing purposes. You don't use the export function of TGATool2 until you've reloaded the tga in TGATool2 and want to turn it back into an ace file.

                        TSRE ShapeViewer will also show a texture preview and export with alphas but you can't load individual shapes.
                        Just an FYI.

                          Using TGAtool2

                          What yellowdog said is what I'm doing now. I never would have figured it out without the TGAtool2 instructions, and even they didn't explicitly say that you have to export the edited image in order to save changes to the Ace but I figured it out.

                            What kind of work are you/were you doing since you found out?

                            Did you solve the problem you were having??

                              Oro tram with transparency

                              Chimbica, at the time you posted, I was still struggling. The repaint of the main part of the tram had not come via TGAtool2, and I couldn't get the transparency back in the TGA I had been finished. Maybe I could have learned the process in Gimp, but instead I opened an ace with TGAtool2 and started over on the repaint. I was able to copy and paste the flag logo, so that saved some effort. This time the transparency was preserved. An image is attached. It's a repaint of Tim Blythman's Melbourne, Australia, B2 tram.

                              What it's about: in November, one evening I was in a taxi in a traffic jam in Cagayan de Oro, Mindanao, the Philippines (my wife is from Mindanao). The roads were jammed with vehicles and people, there were hardly any traffic lights, and I was thinking that Cagayan de Oro could use an elevated light rail line. There's hardly any room to build at ground level, and not only is tunneling expensive, but Cagayan de Oro is right on the coast and downtown is barely above sea level. So even though an elevated line might not be popular elsewhere, it might work there. So I decided to try to make a train simulation of an elevated light railway. I thought Oro might be a good name for the system (my wife agrees). It means gold; Cagayan de Oro is the river of gold. So in the repaint I used colors from the flag of the Philippines and elements of it (the white, red, and blue). I needed a tram that could take tight corners and with explicit repaint permission, so I chose Tim's.

                              I've also downloaded digital elevation and mapping data and applied it with Demex, and I've collected latitude and longitude for places that are likely spots for stations. I plan to design some standard stations and make models of the prominent, distinctive buildings in Sketchup. When I've finished the route, I plan to make a video showing the Oro light rail system as an idea. All this will take a while …
