Hey there,

Try following the format of other example models so you can get a handle on how they are setup and properly loaded in the engine.

You also need to add an entry to the default_map_models.cfg file located in your config folder. Check out the existing list index for reference.

Hope that helps.

Re: How to export 3D models from blender

As the beginning of default_map_models.cfg says:

// Notice: This list is dynamic and will change with every release.
//         Please use a dedicated map.cfg.

Do not edit default_map_models.cfg to add your own models there; this is asking for trouble (it'll break when it's updated in the release).

Instead, use a map .cfg file. You can edit it in-game by typing /notepad, then media/map/mapname.cfg in the top field (which will set the file to edit).

The line you need to add is something like mapmodel "path/to/model/directory/from/media/model/mapmodel".

You should probably limit your FPS to something like 61 using /maxfps 61, I doubt you have a 220 Hz screen.

That is irrelevant to the issue..

Can you upload the exported model with cfg file.

How to load multitexture?

Re: How to export 3D models from blender

Textures must be PNG, JPG, TGA format.  Texture dimensions must be power of 2 (32,64,128,256,512,1024,etc).

For multi-texturing, you can assign textures to different meshes.

objload model.obj

objskin mesh1 texture1.png
objbumpmap mesh1 texture1_normal.png

objskin mesh2 texture2.png
objbumpmap mesh2 texture2_normal.png

Re: How to export 3D models from blender

DDS is supported using the <dds> tag. Here's how you use DDS:

objskin mesh1 "<dds>texture1.png"

You specify the name of the fallback texture (.png in this case) and add a <dds> tag before it.

Nieb: textures can be of any size, even non-powers of 2 or uneven numbers, although it is preferable to have power of 2 textures.

I don't think there's any real point of being so against non power of 2 textures. Well. Besides maybe memory efficiency.
There aren't any Tesseract-capable cards that don't support them.

I think power of 2 is good because it makes things easier to work with on a "grid" which is what you are doing all the time in Tess.
