FBL F40 Locomotives not displaying correctly in TSRE

[wmuzeke]

I'm using TSRE v8.005y. Both Consist Editor and Shape Viewer don't show the locomotives from this set correctly (File ID 89331). They look correct in ORTS. I've tried adjusting the imageSubstitution and imageUpgrade parameters in the settings and it doesn't seem to have any effect.

by what exactly do you mean "not displaying correctly" if you mean that is shows the locomotive but several areas of the loco are displayed with what looks like corrupted texture that is caused by the original version of the "ALPHAS.ace" which was 253x253 pixels which is not a number divisible by 2. All of Nash's locomotive models use the same version of this texture. You can copy one from one of his later releases that use a 256x256 texture to these locos and they will display correctly in TSRE

What you see in the screenshot - the texture for the body of the locomotive is displayed distorted. I did what you said and found a newer version of alphas.ace (256x256) from his recent CN AC44C6M set, but it only makes the cab windows show correctly and not the body of the locomotive. This is also the same if viewed in Route Editor.

If you look in the log file, you may see there are other textures which are not squareable IE divisible by 2.

That is going to be a hard and fast limit due to the way the ace format is rendered by tsre.

there is no screenshot in your original post which is why I asked

I downloaded the set from the file library, as I have been using the pre-release beta version Parker and Nash sent me. which had both DDS and ACE texture options. I have been using the DDS textures and do not have any issues in either OR or TSRE. the downloaded one only has .ACE textures and the F40PH_MAIN.ace is a non square size 2248x2048 while both are devisable by 2 not being quare causes a strange effect when displayed in TSRE.

I am assuming this is what you are seeing.

same model and texture size (2248x2048) with .DDS textures instead of .ace

I should clarify the second picture, that is the shape with textures changed from .ace to .dds in the shape file (from the beta set) all other things are the same with the shapes.

EDIT: Just to be sure I uncompressed the shape file in the download for #600 and edited the shape file to change all textures from .ace to .dds then opend all the ace files with TGATool2A and saved them as .tga then opened all of those with Paint.net and saved as .dds textures using BC3 (Linear, DTX5) setting and got the same result as the beta Versions I have FBL_F40PHM-3_600.jpg

Thanks. It's odd that my screen shot doesn't show up at the top. It was basically the same as your first one. Anyway, converting the F40PH_MAIN.ace files to dds does fix the issue. I used your method, but I did not edit the shape file. In the System Tokens section of settings.txt, if you enable and change imageUpgrade to true, TSRE will look for the .dds file and they show up correctly.

Guess that's another thing for a patch in addition to more numbers and HEP effects and sounds.

As mentioned, DDS doesn't have this issue as it is natively handled. AcE has a custom library that Goku wrote or acquired, and there's some math done there that might not work well with rectangular textures, especially if they have an alpha.
