Great! Thanks Paul.face_off wrote:The light passes are accessed from the Render Passes pins within the plugin.

Thanks Paul!face_off wrote:I have refreshed the installers at the top of this thread with:
2.21.1.27
- Compiled with Octane 2.21.1
- Added Light Passes (you can now assign a Light Pass to each Emitter, and then view each light pass as a Render Pass).
- Added Out-of-Core Textures to the Devices tab - where texturemaps can now be stored in CPU/Motherboard RAM if graphic card VRAM is full. Enabling this sets the RAM limit to your total RAM amount.
- Added "Cube Map" project type to the Spherical Camera
- You can now adjust the new Focal Length slider in the Thinlens Camera to adjust the Aperture
- Added *.TGA to the image file types support for Image, Alpha Image and Float Image nodes

Great, thanks Paul, and thanks for the earlier advice on lighting and textures, will look into it all todayface_off wrote:I have refreshed the installers at the top of this thread with:

What do you mean here? As in create a single shape that would be the emitter? But then the lights wouldn't look like lights anymore no? They would be dark.face_off wrote:I suspect all those lighting in the side and middle of the ceiling are high-polygon Revit family geometry items and will not be ideal as emitter geometry for Octane and render with a lot of noise. In this case, you might be better turning the emission right down on those objects, and add a new object - being a single polygon for the whole ceiling - which you set opacity to 0 and set up as an emitter. This should give a much less grainy render.My default lighting in the scene is pretty strong and there are also a number of emissive textures (the recessed lights at the top of the walls) + natural lighting.
I think what Paul means here is keep the lights but reduce their emitter output and make a new shape like the ceiling you now have, make the geometry invisible (0 opacity) and give it emission properties. Also make sure that only the face of the light fitting emits light.Sonnemanntoon wrote:What do you mean here? As in create a single shape that would be the emitter?

How do you actually assign lights to passes?face_off wrote:Good point Seeker. On your scene Sonnemanntoon, assign the round lights to a pass, and the long lights to another, and render separate light passes to find out which lights are causing the noise. My guess is that it is the round lights. If so - are you assigning an IES light to the distribution of the round lights? http://render.otoy.com/manuals/Revit/?page_id=79
