Stellaris/HOI IV model compatability?

[WeirdoInTheWormstore]

Hi guys

I'm not familiar with working graphics, but I thought I might have some fun importing Stellaris models into HOI IV.

Unfortunately it's not really working for me.

I can import textures from Stellaris just fine, but the .mesh files seem to be in a different format or something, as loading a stellaris .mesh file, causes the game to crash hard.

My question then, is if people can confirm, that importing models from Stellaris to HOI IV is a no-go?

Or if it's possible to load the Stellaris model into some utility program and export it in the HOI format (is that what the maya tool is for?)

It is probably because of the shader used, you have to use PdxMeshAdvanced in HOI4 and Stellaris usually use PdxMeshShip except for portraits that use PdxMeshPortrait and some effects that may use an alphablend shader.

You can change shader manually in the mesh in the .gfx file where you have the mesh by writing

meshsettings = {
            shader = "PdxMeshAdvanced"
}

So it will look like

pdxmesh = {
        name = "arthropoid_01_bomber_mesh"
        file = "gfx/models/ships/arthropoid_01/arthropoid_01_bomber.mesh"
        scale = 1.0
            meshsettings = {
            shader = "PdxMeshAdvanced"
            }
}

Thanks a lot, that helped a lot - no more crashes, and the new units seem to work fine in terms of game-mechanics

Graphically though, I've hit another snag, as the animations in HOI are apparantly not compatible with the models from Stellaris.

Loading the unit, I get the log-error:

[22:08:09][pdxassetutil.cpp:1290]: Didn't find skeleton in mesh file
[22:08:09][pdxmeshtype.cpp:326]: Animation [fighter_default_idle_animation] is not compatible with mesh [avian_01_fighter_mesh]

The animation in question, I think is 'fighter_default_idle.anim' and I guess it makes sense that it's not compatible with a completely different model. I'f I remove the animation from the planes.gfx file, the error is gone, but of course, so is the animation and all other graphical representations of the model in-game

        pdxmesh = {
        name = "avian_01_fighter_mesh"
        file = "gfx/models/units/planes/avian_01_fighter.mesh"
        ## animation = { id = "idle" type = "fighter_default_idle_animation" }
        meshsettings = {
            shader = "PdxMeshAdvanced"
            }
    }

I'd copy the animation file from Stellaris as well, but the avian_01_fighter, corvette and destroyer so not come with animation files as far as I can tell, and I'd rather not mess around with the more complicated models like the cruisers and battleships.

My question then is this: How would I go about tweaking the HOI animation files to my stellaris model, or is that a major operation? If I can't make it work with the fighter model, I think I'll give it a try with the constructionships, as they come with animations, and a fairly simple file-structure compared to the capital ships

EDIT: Tried the Stellaris constructionship, which runs without any error messages in the log. But unfortunately also without animations :/
