OTOY Forums

I'm new to Octane .. and also Blender, but getting the hang slowly I have a question regarding lighting:

Using the Blender Plugin to Octane, I created just an ordinary cube, assigned it a wooden material from the liveDB, went inside with my view, added an extra wall with a door to basically create a simplistic tworoom environment. I wanted to use it to understand lighting a bit better. I placed another object, another cube, in the air of one of the rooms and set the little cubes material to be octane diffuse with an octane emission node connected to the diffuses emission connection ... I expected this to be a glowing cube.

But there my confusions starts:

- The cube does nothing .. it's not glowing, although its material preview is (Also: sometimes, the preview does not show the proper material, it sometimes shows the wooden material of the surrounding two room box in the preview)
- I moved my viewport to be inside the box, in the room with the cube. If I have my render settings on "direct light" with "ambient occlusion" ... I see the rooms, walls ... even if I delete the emission cube (which does nothing anyway). Why is that? I was expecting to see nothing at all inside a box without any light.

Probably ridiculous questions to most of you, but I got confused.

Hi, I also Blender/Octane plugin user, upload your test.blend to http://www.pasteall.org/blend/
I can take a look.
Ambient O. is a simulation of light/shadow.

If you switch to any other render method scene gets dark.

Cheers, mib.
P.S. It is may better to post Blender Q. in Blender plugin forum thread.

Cheers, mib.

Thanks much for the answer. Strangely, now that I have restarted blender and recreated the cube, it seems to work ... now I have doubts if I made a mistake :/

Thanks for your answer, though
