Why can't cycles cast one ray per image pixel, instead of rendering progressively to infinity?
I am wondering why Cycles renders progressively to infinity. Why is it not possible to do one ray per pixel in the image, letting you have a finished result with X * Y rays cast? I suppose this question could apply more generically to raycast…

Can Cycles use multiple UV layers?
I'm trying to match Cycles to a Blender-Internal material setup and I didn't see a way for cycles to have an image reference more then one UV map.
Is it possible to have a node setup with 2 image textures, each using a different mesh UVLayer?

How to access Render Result pixels from python script?
Render Result exists in bpy.data.images["Render Result"] but it contains no data.
Also bpy.data.images["Render Result"].size[0] is 0, even if the render shows as an image in the UV/Image Editor with a width of 1366.
Maybe the render result cannot be…

How to disconnect selected mesh geometry?
I don't know how to disconnect a face from the rest of the mesh in edit mode.
This isn't like pressing P to separate the selection into a completely different object. I just want to select a face and disconnect/rip it away from the rest of the mesh…

How do I avoid rendering glitches from overlapping faces?
For instance, here I have two cubes that are offset only on the x-axis. When I render them (using Blender's internal renderer), the overlapping faces interfere with each other and the result looks awful. A quick and easy solution would be to offset…

How to display different layers in each 3D View?
How can I show different layers in separate windows? For example, show layer 1 and 2 in one window, and show layer 3 and 4 in another window?
I need this so I can see everything I am doing correctly since I do have a messy rig.

Is it possible to render vertices in Blender?
Is it possible to render vertices with materials applied on them?
I subdivided a mesh, and deleted all the faces so only the vertices were left.
I could theoretically apply cool effects on them (I think it could be useful in motion graphics), but I…

I have a plane in blender with a image texture node, connected to a RGB to black and white node connected to a multiplier before being connected to the displacement of the Material Output node. There appears to be some shadowing on the plane but it…

Does Cycles work with wave optics?
You know how raytracers pretty much just trace geometrical rays? I was wondering if Cycles has any wave optic features, where it would act as an actual electro-magnetic wave. Some really useful features would be diffraction, Interference, and…

Suppose I wanted to animate an object growing out of the ground, or turning from a cube to a much smoother shape, could I animate this using modifiers and key frames?
I know I can use shape keys to achieve something similar, but modifiers would make…

How to configure blender so that it uses only 50% of total CPU when rendering?
I need to render a very computer-intensive scene using cycles and for some reasons, I decided to use my home computer (i5 3.30 Ghz, 10 GB RAM, 2TB Hard Drive) to render it. However, the problem is that many people needs to use this computer. So,…
