Area light visible to daylight!

Hello,

A simple scene with a plane ground, a sphere and 2 area lights.

When I enable daylight, it sees the area lights shapes and casts shadows of them. Any way to disable that? Thanks.

Looks like a bug to me.
Temporary solution for this is to set area light Diffuse material opacity to 0 and turning on Transparent emission in emission parameters.

There isn't any "Area lights" in Octane, they get converted to meshes (planes).
And that's why they have shadows.

But that might be one for the "wish list"/feature requests that:

• Area lights by default don't have "Shadow visibility" set to false (just as "Camera visibility" is set to false by default)
• There's an "Shadow visibility" option for area lights (this exists for meshes in the Blender UI, would be nice to have it for area lights as well).

Personally I tend to just stick with planes/mesh lights, but area lights can be handy and in some ways "easier" to work with..

Yes.

I noticed many incomplete features compared to other integration plugins. Like the local db and also some nodes. For instance the absorption medium node is completely diffrent from the one in the standalone octane and other plugins.
Do you think this is due to some lack of functionality in the Blender Api?

Importing orbx like in cinema4d is also missing!

These are same just have different name convention. Density = Scale

The Blender node has 2 inputs (Absorption and Scale) while the standalone node has 3 (Density, Volume step length and Absorption)!
How do you refactor 3 inputs into 2 and get the same result?

[J.C]

Scattering and absorption medium has all the inputs.

Step length is used only with volumes like fire or smoke and is available in volume medium.
