Lights with Octane Render for Rhinoceros

[borifazi]

Hello! I'm new here and I'm trying to learn Octane Render plugin for Rhinoceros. I've a spotlight in the scene created with Rhino, but I can't see it in the render. How can I use a spotlight created in Rhino? Is it possible? How can I put direct lights? Thanks

I use Rhino, but don't have the plug-in. For all lights, simply create a geometry (a sphere perhaps). THis will be your light, now place it where you want it to be, then assign a diffused material to it. There is an "Emission" attribute, set that to blackbody (for beginners) and then play with the power and other setting until you get it the way like. Textured works too, but you have to play around the more settings.

You can also use surfaces, cylinders, and many other shapes. I recently modeled a studio lamp with French flags and all, then created the emitter "bulb" and it worked perfectly. Keep in mind, a multi-light set up will take longer to render.

Good Luck.

Here is an example using 3-point light setup. THe lights are thin cylinders 60cm diameter x 2.5m height

Sample three point light 1500 samples

Thank you kraken, recently I've found that solution. Somewhere I read that it was indispensable to use ies light but I tried with a simple plane and it worked. Very interesting your render, I like very much the lights' effects. Bye

Hi - as mentioned above, you need to use geometry for your emitters. Pls see http://render.otoy.com/manuals/Rhino/?page_id=79 for details. You can also automatically convert Rhino Rectangular Lights to Octane emitters by selecting the light, and then clicking the Create Emitter button in the Geometry tab.

Thanks, this one I didn't know. It'll be precious in the future. Bye
