[Qgis-user] [Plugin][qgis2threejs] Set the elevation base of the model with the first value of DEM

[Nicolas Cadieux]

Hi, 
I am not sure about about the setting of that plugin but I would look at how many pixel you have between 0 and 265.  If you have none, then your layer starts at 265 and therefore you have 2 zero values ( 0 and -9999) but only -9999 is recognized by the plugin. 
Start by adding 0 as a zero value.  There is a setting for that somewhere in the layer properties (top right window).  (I'm far from my computer).  
Try the plugin again.  It may or may not recognize that setting.  If it does not, use the raster calculator to create a new file containing only pixels above 265. 
It will look something like   (DemX=>265) * DemX 
Then try the plugin again should work and be scaled properly.

	Hi guys, it's is possible set the base o f the 3d model to the first value of  the DEM? Imagine this, i have a dem clip that starts with elevation 265 meters and goes to 327 meters. When i run the qgis2threejs the output start from 0 meters (i guess that is the surface above water) and give me a "big exaggeration" of the model. If i change the exaggeration factor to small factors such as 0.01, 0.05 to reduce the exageration of the model (provoked by the 0 meters) but the model became to smooth and lose the detail of the terrain. Another thing the nodata values in this case is -9999, this could be a problem? Best Regards, João
