visible or volumetric light in Octane

[deifgiri]

Hi octaners,

I'm building a scene with lots of lights, actually it is the typical carnival hammer or a high striker...
I've been struggling with all parameters of textures and lights with no luck at all, I can't get the lights to be turned on, with brightness emitting real light from inside the bulbs.
I checked the forum about the volumetric light trick following this post: http://render.otoy.com/forum/viewtopic. ... tric+light with no luck either. Also tried to make a diffuse texture with emission, but no visible light again.

The lights inside the bulbs are AREA LIGHTS if I add more power via 'Octane LightTag' to them all I get is to burn all surrounding textures causing Octane to make lots of noise (annoying white pixels) in the render.


I'm uploading the scene if someone can help (R15)

This is how I would like to have the lights turned on, to be real lightbulbs!

i hope to get help from some experienced users before i do somethings.

But i have to say some truths about your usage:
you are far from optimised workflow on Octane. I'll be suprised if you don't get Cuda errors with big scenes. Do you know any info about Octane Objecttag? You should use it for working with interactivity. Don't forget render instances, which are good options for producing low polygons. Also be aware that Octane doesn't love high polygons. You are using very high subdivision on hypernurbs. Octane uses render subdivision on Picture Viewer.

For lighting,
you are trying very hard situation for tracing. A emission in a polygon with specular material. Also your scene is not real world scaled. It's not good idea. It's very hard to produce realistic images with ten times big objects.

Thanks for your quick response,

first, and to be honest it is my first project using Octane, so I'm kinda newbie, I'm aware of too many polygons and subdivisions, the project is sending 800MB to the card, too much, still it renders fine, I'll reduce the polygons and scale.

But all my worries now are to get this lights visible, I'm making this animation where the hammer hits the striker and then I'll turn all the lights on and off until the top.

here's a screenshot for now, it's quite nice but the lights:

any help will be appreciated,

teşekkür ederim
