I’m using Blender for 4/5 weeks now, so, after learing the basics of modeling (i’m still not even decent), now i’m having some issues with Render Setup and Lights Setup, and i hope someone can help me out!
The Lightbulb
I’ve modeled a really simple dog-character for an upcoming work. Having a lightbulb for head, i need it to emit some glow/light. I need a result which looks like the FIG. 2 (lights are made with PS), while the one i’m having now in Cycles is kinda flat FIG. 1 What’s the best way to achieve it?
Even if my scene is almost…empty (1 model, 2 lights) seems like my Pc is working really hard (and slowly) to manage it, both in 3d view and rendering session.
Windows 8 - AMD Phenom II X4core 965 Processor - NVIDIA GeForce GTX 560 Ti - 8GB RAM
Not a beast, but still decent enough for a project like this, i suppose. (and i’m not forcing it, since render is still really noisy) Since i’m supposed to build a scenario and rig/animate character, having a 17/20 minute render time (for a frame) is really discouraging me I’ve attached the Blender file, to see how i’ve set the render.
What’s wrong with it? Am I doing something wrong with modeling or scene general setup? How can i have to speed up the render? Any suggestion will be very appreciated! :>
Hi, had a short vie to your .blend.
First it is freestyle activated, this is a non-photorealistic render engine for comic render.
Your settings in “Light Pass” are extreme, start with Limited Global Ilumination.
The filament emitter is very small so you need very high emission settings, make it as big as possible or fake it with several point lights.
Your glass has no thickness, use solidify modifier, IOR setting is wrong.
Provided your background/ground mesh is mostly glossy and you’re using clamp direct value less than 1… Translucency inside the bulb and all what @mib2berlin mentions - no wonders your render times skyrocket.
For the filament you could use LightPath IsCameraRay to not to let this tiny emitter interact with other mesh but show only to Camera.
I’ve attached the Blender file, to see how i’ve set the render.
