There seems to be vertex boundaries, out which polygons (or objects) are not rendered.
when I used the following plane vertices
-10.5, -10.5, 0.0, 10.5, -10.5, 0.0, 10.5, 10.5, 0.0, -10.5, 10.5, 0.0
I can always see the textured plane rendered. But whenever I changed the vertices to one of the plane polygons that form the actual object ie
-3.37671, 4.82752, 0, -2.99017, 8.33082, 1.4426, 1, 8.26176, 1.6177, 1, 4.97105, 0.8794
I loose the rendering
I could not come up with any other reason than that there are boundaries outside which the polygons are not rendered.
Is there any other explanation for this ? otherwise...
What are the vertex boundaries?
If someone can spare some few minutes and also try to render the same poly, does it render?
