I'm a bit confused about the materials terminology in Octane, being used to the properties in Lightwave and Modo.For example, in either program you can raise the specular property and see the effect on the material, which is kind of a fake reflection, even if it's not exactly that in theory. But it makes the surface looks less flat. Or, I can make a specular texture for it, or apply one from an object that I got from someone else, or that was in the Lightwave content for example. As you know, most objects usually come with a diffuse texture, a specular one and sometimes a bump one if not more.
The problem is that the Octane diffuse material doesn't have a specular input. It has a transmission input that I'm still not clear what it does. In the manual, all it says about it is this:
"Transmission: The Transmission value gives the base color to the mesh."
However, when I move its slider all it does is make the texture lighter as it reaches 100%.
The only material that has a specular input is the glossy material, but what if I just want specularity, not reflection? For example in the case of the grass in the LW content, which has a diffuse and a specular texture, if I use a glossy material and I connect the specular texture to the specular input, the result is grass that looks like is made of mirrors. So for grass I have to use the diffuse texture, but the blades look rather flat without its specular texture. How do I apply the specular texture of this or any object to an Octane shader?
Thanks
