Real Diffusion Channel/Map Layer

I would like to request an actual diffusion channel and corresponding map for diffusion material.

Color and Diffusion channels are not the same thing.

A color channel is needed, but a diffusion channel is also needed with corresponding map.

I am not sure if this is somehow taken into account by the absorption value but I would like to know how this works with the existing version of Maxwell or if this is planned for future implementation to be announced at a later time.

I'm not sure this is necessary....Maxwell doesn't treat materials in the usual Phong etc shading models...

In reality it's all reflection. Either diffuse reflection, or specular reflection. The diffuse IS the objects color, or better said the object absorbs all light except the color you see, which it reflects back.

I will take your word for that Mihai, thanks for the helpful explaination. I can understand the connection with reflection very easily. This would help in making a reflection map if I want some areas to absorb light more readily than others.

How do you do this with the current version of Maxwell Alpha?

I would then want to test this for compatibility with same some diffuse maps that I might make in the future.

Can all of this be more simple then talking about specular and absorbsion and all that. Can we have in the material editor like images of things like a computer white case to use its texture on a modeled computer, or a cocacola aluminum can to use it as so... this will be very very simple as everithing will automaticly ajust to the objects, we only have to drag and drop.

Same for the sky, lets say i want a clouded sky with just a little sun comming thru.

Well after all textures do not have to be so complicated, NextLimit has to make this procces less complicated, they are gods right??? :wink:

Hello Nicolas,

Actually I want the option to be able to have the flexibility of using maps to give materials more realism. With things like the specular map you can put finger prints on things and such or small little water stains here and there.

oohh ok Tyrone, yes your right, its me that i'm not familiar with those terms and proceeders.
