Rendering Fails when choosing extrudeHeight

Hi,

When I enable ExtrudeHeight; then Rendering fails after loading couple of the polygons.

There are 56 polygons

You could see the full error message on:

This is a screenshot of the error

Any help is much appreciated.

What browser (exact version), OS, and video card are you using? This looks like an issue with outdated video card drivers so that’s what I would recommend as a first step to fixing the issue.

It seems that it was somehow related to the too much detail in the polygons.

I was using some very high resolution polygons that was coverring the coast lines very accurately. Somehow that was causing the rendering to fail.

Once I switched to a simpler polygons everything works just fine.

I check on the Graphic card driver too. The graphics is the Intel HD 4600. So not a strong one.
