Since I struggled with getting objects to emit light on the last project, I decided to focus on figuring out emission textures and practice my spline modeling skills by building a light bulb.
At this point I feel a lot more confident using the spline tools to model. I have a tendency to try and box model everything but I built the light bulb using mostly Loft and Sweep generators.
This scene is fairly simple. Two area lights aimed at the bulbs from each side and an OctaneEnvironment for some fill. I still don’t have a complete understanding of how the emission works for tiny light sources, but I’ve reached out to the Octane user forum for some help. Hopefully someone with more experience can help me shed some light on the issue. Ha.
I think I’m gonna come back to this scene again at some point and spend more time getting the textures a little more worn and realistic. I was going for a modern design with the connector plug but the white plastic isn’t working for it anymore.
The rendering was a little tricky with this one and I’m still waiting to hear back on what the most optimal settings are, but I used the PMC kernel at 2000 samples and set the GI clamp and Caustic Blur to 1. It was estimated to take 47 minutes but I stopped it around 19 minutes in and decided to start grading it. I figured i'd render it again with better settings so there's no sense waiting all night.
Either way, good project, good learning experience.
Here’s a screenshot of the scene setup. I used some google images for reference, also attached below.
