"I'm mentioning this because without radiosity, diffused surfaces will not work properly. Instead, they will just appear too dark. "

after reading the whole workshop & also doing it practically i realized that the diffusion is not so so so so important, the same effect can be achieved by changing the color of the color map.. because in the end the difusion map is really affecting how much light is scattered i.e how much color we can see...

also i want to know that leigh stated that diffusion effect of diffusion can not be seen incase u don't have the access to radiosity engines.... so i think diffusion is merely important to lightwave user not the other user....:shrug: :shrug:

Using diffusion is important in order to prevent surfaces from becoming over-saturated when lit.
This is the same in any software. 100% diffusion causes nasty over-saturated hotspots to form on surfaces where the light hits them.
As for radiosity, I never said that diffusion only works with radiosity - I mentioned that it works nicely with it.
Most software renders include radiosity nowadays anyway, not just LW.

do u think the safe effect can be created by tweaking other parameters or manipulating infact color maps to some extend...
rather than working so much on diffusion map
