OniSplit does '''NOT''' require exactly power-of-two textures for importing via XML or <code>-create:txmp</code>. I've tested it during testing 8192x8192 lightmaps. The table of power-of-two textures in OniSplit is only up to 1024. So, my 8192x8192 textures are not power-of-two (according to OniSplit's warnings), but they are working just fine. <code>Note: I'm using "vanilla" OniSplit version 0.9.99.0. This note is important, because I have modified version of OniSplit from GeySer.</code> All proofs will be soon in my Engine-Demo video (featuring "smart" animated textures, hi-poly physics, lightmaps, holographic characters, etc.).

Same problem with 0.9.99.0. Actually two things happen.
  1. OniSplit converts 512x499 to 512x256 if -create:level is used.
  2. They colors get distorted. While the change in dimension seems intended, the later seem to be a bug. When you convert the TXMP back to jpg it has wrong colors. So this is not an engine problem.--paradox-01 (talk) 13:52, 31 October 2021 (CET)

Let me explain the situation in more detail so we all are "on the same page".

This is a trimmed example (code) of a level import with onisplit -create:level outputPath inputPath/lab.xml

lab.xml
<?xml version="1.0" encoding="utf-8" ?>
<Oni>
   <Level SharedPath="../shared">
       <Environment>
           <Model>
               <Import Path="env/lab_env.dae"/>
               <Import Path="env/lab_motorcycle.dae">
                   <Node Id="motorcycle">
                       <ScriptId>9</ScriptId>
                       <GunkFlags>NoCollision</GunkFlags>
                   </Node>
               </Import>
               <Import Path="env/lab_elevator.dae">
                   <Node Id="AnimElevator">
                       <ScriptId>540</ScriptId>
                   </Node>
               </Import>
               <Import Path="env/lab_bomber_window.dae"/>
           </Model>
           <Rooms>
               <Import Path="env/lab_bnv.dae"/>
           </Rooms>
           <Textures>
               <Texture Name="TCDOORGLASS">
                   <Format>bgra4444</Format>
               </Texture>
               <Texture Name="GOO">
                   <Format>bgra4444</Format>
                   <GunkFlags>NoCollision</GunkFlags>
                   <Image>env/images/GOO.tga</Image>
               </Texture>
           </Textures>
       </Environment>
       [...]

As you can see it is possible to declare individual texture properties in <Textures>.

But the usual case is to not use it for reasons of comfort. When you have a level with 2000 JPG / RGB standard textures you don't want to declare that many "exceptions" or even write individual TXMP*.xml files. Usually you simply build your level in XSI or blender and OniSplit will convert the referenced JPGs in the DAE file (here "lab_env.dae") to standard TXMPs. This works perfectly fine as long as you have power-of-two textures.

So all I'm trying to say is that -create:level will produce correct TXMP if power-of-two is used. But -create:level will produce corrupt TXMP if non-p.o.t is used.

You should check the source code of OniSplit that handles the automatic scaling of non-p.o.t textures when -create:level is used.

-create:level is such a great feature for the modding community and should be made bug-free. Also: only tga, jpg, png can be used for the AKEV core geometry and -create:level combination.

I hope we are on the same page now :)
