Vray 3dsmax, specular/reflection color and specular/reflection amount

Hi,

I'd like to know how you would drive the specular/reflection color and amount separatly in 3dsmax especially if you want to drive them with a texture map.

In vray for maya the specular/reflection color can be mapped aswell as the amount.
In 3dsmax they are linked together and they can accept only one map for both parameters.

I tried to use a mask in the reflection slot to get the specular color map driven by the mask which has a specular black and white map.
But I don't know if it is the regular way of doing and I'd love to hear some feedback.

Thanks

A blue reflection, say, at 100% would effectively be the "white", pure reflections multiplied by blue. This is the case whether you're separately controlling the colour and the intensity, or if you use a single map for both. In other words, you control the "amount" of reflections by the luminance of the map.

(In Max there is also a 0-100 range in the Maps section of a VRay material, but this is basically just the "opacity" of whatever's in the slot, layered over the colour of the slot below. As such, if you put a bright colour as a map into the reflection slow, have the actual colour of the slot as black, you can effectively use this number to control the intensity of the reflection. But it's not really doing anything you couldn't just do with the colour on its own).

Thanks.
The issue with those combined control is that I'm obliged to manage the intensity and my color at the texturing stage.
And frankly I have a hard time figuring out the result I will have.
Plus it is quite difficult to tweak the color or the amount separatly.
I probably have to use a composite.
