Does OGRE support texture packing?

[sercero]

Something like this: Blender - Texture Channel Packing

[paroj]

yes, it does:

ogre/Samples/Simple/include/Terrain.h

Lines 519 to 521 in a98c9ee

	Image combined;
	combined.loadTwoImagesAsRGBA("Ground23_col.jpg", "Ground23_spec.png", "General");
	TextureManager::getSingleton().loadImage("Ground23_diffspec", "General", combined);

however, it is more efficient to do this at export time with e.g imagick:
https://ogrecave.github.io/ogre/api/latest/tut__terrain_sky_fog.html#bt3MergingTextures

Does it make sense to add this to blender2ogre, do you think?

[paroj]

I got the impression you can do this directly in blender without any exporter support, no?

[sercero]

I don't know.

If you look at the video it seems that they guy has to make a special setup in Blender in order to pack the textures.
