Diffuse is the color of an object in 3d programs including DAZ Studio 4.x. Here is the Wiki Page for Diffuse – http://docs.daz3d.com/doku.php/artzone/pub/software/dazstudio/reference/st_diffuse
You can find the Diffuse on the Surface Tab. loading most objects will load the DAZ default shader.
A discussion about the Surface Tab is incomplete unless you discuss the Lighting Model. Many objects load with the lighting model of plastic unless the author made more specific shader presets. The Lighting Model are choices in the way the render engine interprets the specularity of an objects surface. So with the previous statement you would assume it has no effect if you are only playing with the Diffuse Channel. Not so. It seems that the Skin Lighting model does effect Diffuse. See below.
The Glossiness of the Diffuse surface seems to be expanded and softened compared to the plastic lighting model. But also brightened or stronger. Glossiness is directly tied to specularity so this make me even more curious since the Specular Channel was at 0%. So I will now turn the Specular Channel up to 100% and show the effects of Glossiness.
Specular and Diffuse at 100%. Plastic Lighting Model. Spotlight 100%. At Glossiness 100% with these setting there is no specular highlight.
There are really billions of different settings and combinations of settings for the DAZ Studio 4 Surface TAB. Diffuse and Specular are the 2 most used shading channels in any product. Many times there are maps associated with the channels. Next chapter will continue with Diffuse, Glossiness, Specular and Lighting Models on the DAZ 3D Studio 4 surface tab. Happy rendering.
Anytime you render in a 3D program it will take up ALL of your computers resources. My 7 core 17 computer kicks in the fans instantly after hitting render. One trick I learned is to change the affinity of Daz Studio 4.5.
Every time I open Studio I then open Task manager (Ctrl+Alt+Delete), open the processes tab, find DAZStudio.exe, right click on it, open the “set affinity” which pops open the list of your processors cores. I usually chose 4 or 5 of my 7 cores to run with Daz Studio at any one time.
It probably slows down my render times but I can do other things on my computer as well as not maxing out all my computer power at one time. I don’t think it is healthy for my computer to be running at full bore for hours at a time while rendering an image. Or even when you are test rendering to be stopping and going a hundred times. Daz Studio 4.x will each all of your computer resources. Control this by changing the affinity.
