terribly sorry. There was scaling problem.
I just scaled up the model size to multi folds.
I could get it.
But tethering to model is not working fine for me.
Instead, if setTherNode (to the geotransform node) is set at node callback, it is happening.
Second thing, the model is appearing complete white. Setting of GL_LIGHTING to on/off, switches
only the model color to complete white/black. But model alone rendered complete texture is coming
fine with no issues.
Even attaching shader to the model node makes it only whiter from dark.
Texture is not visible.
I have another issue that when I tilt the earth, the model is getting clipped (hidden).
The model is visible only at particular view point.
