There is a way in indigo to generate sphere in the render:
Code: Select all
<sphere>
<uid>3</uid>
<center>0.0000 0.0000 0.0000</center>
<radius>1000</radius> <!-- meters -->
<material_uid>2</material_uid><!-- use fog material here -->
</sphere>
I think that this is the same allorithm to create the environment sphere how have the HDRI to enlight your scene.
Is this generated geometry have the exact same shape each time that I launch the render?
Because I have the strange feeling that the generated IGI merged from several nodes give a stranges result in the sky because I have "dark shadowed triangles" .
Of course I do not have this problem when I render on worksation this appear only when several render nodes are used.
so please confim
