Maybe someone has some info that might help me out. The only thing I
can think this could be is the scaling problem that comes up when
someone tries to render our solar system and a pencil on earth in real
scale in relation to each other - something to do with working with
really large and really small numbers at the same time.
I'm trying to render a mesh2 and am running into some problems with the
pigment on individual triangles.
The following scene is a single mesh2 face that was painstakingly
isolated so that I could better understand the problem.
The first image is the render of the scene - a white triangle, not the
expected results.
But if I modify one of the vectors I get something similar to image #2.
image 2 - modify vector 1
<57312.569,784.27165,53547.105>, original
<57312.568,784.27165,53547.105>, modified
^
But results vary with what I modify - image 3
image 3 - modify vector 2
<57310.236,784.35367,53548.234>, original
<57310.237,784.35367,53548.234>, modified
^
Image 4 is what the big mesh looks like with the little white faces
sticking out like a sore thumb. The white face on the far right is my
example face that I was able to isolate.
This is not a mesh that I want to modify by hand. It is about 400,000
faces with about 200,000 vertexes. The final scene will likely have
many more faces and vertexes.
Does anyone know what might be going on, and/or know what can be done to
fix it? It would be really nice to get rid of the white as it detracts
from the presentation that we are trying to do.
