Diffuse Roughness

[mjr3d]

Perhaps this has been discussed elsewhere, but I am unsure of how to utilize the roughness feature in the diffuse channel. When I read about it in the VRayMtl examples section on the spot3d.com site and it mentions inputing a numeric value, but I do not see a box to plug a number into, just a channel I can map. Can anyone tell me how to properly utilize this feature?

Thank you for the help!

Hi
We have missing the numerical input box, but you can use gray scale color to control the roughness. 0 = black color and 1 = white color. You can also use gray color if you want something in between black and white. We are planning to include the numeric input box in the future.
