Confused about node behavior
Posted: Tue Mar 27, 2012 9:56 pm
Hi,
This is with regards to the Octane demo:
I am a bit confused as to some of the node behavior.
If I start up Octane and import a mesh into the unsaved project (only node on screen), I can adjust its parameters and watch the changes in real time. How is this possible when no other nodes are present except for the nodes in the Preview Config. Macro which I thought was just a macro you could build upon if you wanted to copy its contents into your unsaved project? In other words, aren't the Preview Config and Unsaved Project tabs two separate "realities" that don't talk to one another? My first tests seem to say they DO interact.
Now, if I delete all the nodes in the Preview Config Macro (the only node that can't be deleted is the Render Target node), then my rendering goes black. So I go into my unsaved project and add camera, target, environment, etc., but now I cannot change the mesh parameters in real-time...The render just goes black. I can only watch the render in real-time when the RenderTarget node is clicked, and RMB>"Render".
One last item...If I do not add a Material node to connect with my mesh, but instead just use the material sliders in the Mesh node, If I choose "Specular" as the material type, I find that all of the sliders appear to work correctly except for the Index slider...the Index behaves as if it is always zero. But if I add and connect a Specular Material node to the corresponding material pin on the Mesh node, refraction behaves normally.
Thanks for any help!
