Cinema 4d dirt effect

[pauldoherty]

Hi all;

Can anyone tell me a good setup for using cinemas dirt effect

to make my architectural v's more realistic and not so polished

or plastic looking.

you can use the dirt shader anywhere it's available...totally totally cooool LOL

 

As part of a mix for the color channel, in the diffusion channel, alpha channel, use it to dim refelctions.....

 

in a layer shader set to multiply-dirt-fakiosity, in an alpha shder, when it smells like almonds (SLA)........

 

as a dirt pass and composite at will in post....

 

the possibilites are endless

 

The most basic uses:

Shader in the color channel- then use rendered image to screen, overlay, multiply.... in PS over the actual full rendered scene.

Same lines no compositing....use it in the diffusion channel, tweak the % & mix values to your liking, super grungy dirt or just a hint of dust LOL

 

Dirt shader itself....

play with the settings LOL and turn on radiosity

 

Ray Bias= I leave it alone (RTM)

Distance=distance of spread-reach of dirt

Rays=number of dirt rays cast, more is smoother & longer calc time for dirt

Ray Spread= controls the even spread, 100% linear heavy to light, less than 100% forces a curved response, heavier at the source.

Contrast= Contrast darkers darker & lighter areas brighter

 

Included an 8.5 file for the image, Happy Holidays

 

Does that help?
