Heightmap File Name from TerrainSceneNode

[gbutcher]

I'm writing a scene editor that exports the scene to a .zip file. I need to retrieve the heightmap file name from the terrain scene node, but I can't find a suitable method to do so. Any ideas?

The only way that I know of is a bit of a hack. You can use the serializeAttributes() method to get the attributes of the scene node, then query the attributes object for its Heightmap attribute.

I posted some code a while back to get the name of a mesh used by an oct tree scene node. You can see that code here.

Thanks, I'll try it.

Didn't get to try it until my next business trip, but it works:

Code: Select all

ITerrainSceneNode* terrain = (ITerrainSceneNode*) smgr->getSceneNodeFromType(ESNT_TERRAIN);
    io::IAttributes* attribs = device->getFileSystem()->createEmptyAttributes();
    if (attribs)
    {
      terrain->serializeAttributes(attribs);
      core::stringc name = attribs->getAttributeAsString("Heightmap");
        wxLogMessage("  heightmap: %s", name.c_str());
      attribs->drop();
    }
