I am thinking the maps should be used in following ways, but really not sure. Please advise

Reflection maps=roughness?
Transparency = opacity?
Gloss map= specular?
Mask Map = ???


Thanks for help

Hi,
Reflection maps= node > environments > texture environment > rgbimage
Transparency map and Mask map = opacity
Gloss map= specular black=0 white=1
Roughness= node roughness, regulates the gloss specular node
example: you can create a glossy material, apply a saw wave generator to channel specular, then applies a generator to the channel roughness.
So you can see how the channel interferes roughness on specular channel.
I hope this helps you understand, what kind of image you have to assign to the different channels.
Correct me if i'm wrong.

what specifically are you looking for with a "mask map" that is different than opacity? I might be able to give you some insight on that.

From Top left: Albedo, Gloss, Normal, Translucency, Cavity, Displacement, AO, Bump and Alpha.

Wow! Rikk no wonder you works are so detailed. With this many maps its bound to give great detailed images. Thanks for sharing.

I know how to use in OctaneRender:

Gloss, Normal, Displacement, Bump and Alpha.

And as far as I know it is not recommended to mix Normal, Bump and Displacement together in OctaneRender but to use just one of those types for each surface.

But can someone show some examples how to use in OctaneRender:

Albedo, Translucency, Cavity, AO ?

Hey thanks, but I have nothing to do with the image above, it's taken from QUIXEL website, I thought it was a good example of how maps should look.

Albedo is just the pure color of your texture, and you need to plug it into the Diffuse slot of your material.
If you have a Translucency map, you need to create a Transmission node, and plug it in there (only Diffuse material and Specular material supports it, you can't use it with Glossy)
There isn't a dedicated slot for Cavity, so if you want to use it, I suggest to combine it with the albedo map in Photoshop.
AO maps are useless in Octane, as you already get an accurate ambient occlusion from the renderer.

Thanks for the input. Especially the samples given by Rikk. I will try them out.

Thanks。 Very helpful
