Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Some important info about final gather you may or may not know about.

The final Gather option creates very realistic shading effects by bouncing an objects "COLOR" onto other objects, as in real life. When Final Gather is turned on, light rays are cast from the light; then when the light ray hits an object, additional rays are projected from the object used to calculate the amount of energy that is comming from the the surrounding objects, in turn producing the effects of bounced light and color. To a point, Final Gather turns every object into a type of light source.

Here is some additional material with illustrations that demonstrate the process. Linkage

Hope you don't take offence at this, just trying to help out if it pleases.

yeah i read that you dont need any light sources using final gather as the object colours use each other to produce light from each object background aswell..
(is that what u just said)
or have i added im not sure.

Ya its true.. the one object light I use is just like any other object in the scene just a regular cylinder with a surface shader that has output color value cranked up to 100, effectively becoming a light source. I'm going to reconsider alot of stuff.. that link had tons of information that I wanted to know. I have to struggle with memory constraints on my computer so all that info will be helpful in optimizing my scene.

Magicsy, you can use light sources with Final Gather. You just have to learn how to use them properly. My Life force Snake I entered in the Sept/Oct challenge, I used 3 spotlights to light it. I would like to note that you have to use "Ray Traced Shadows" . Final Gather is a raytracing process which enables/requires Mental ray raytracing mode. When Ray tracing is set to off, FG is not active.

Magicsy, dilberts, and Mayafreak3, your very welcome for the link.

I highly reccomend that you guys read everything thats provided in the link. Read it till you can comprehend what it's teaching. The hardest thing for me about Final Gather was understanding how the FG rays worked.

hope simplymaya doesnt mind me mentioning this, but Gnomon have an awesome video on using final gather in combination with other lighting like global illumination...(59 bucks, but worth it). https://thegnomonworkshop.com/dvds/mha03.html

Thanks muteking1. user added image

The wall is a colormap and a bumpmap with a phong shader. Just textures.

Here is my latest render:

Awsome render!:attn: That vintage look really grabs ya.

Varley, I have seen some of the Gnomon workshop series. Thay are put together really well. I wish I had one on the GI. I think the 60 bucks is a bit steep just for a dvd.

nice render user added image
thats definately looking more realistic. Just a quick sharpen in photoshop (not the wall and carpet) and it'll be great
