Specular Conversion

Mon Sep 21, 2015 4:47 pm

For some reason when I convert a material from a modo material to an octane override it is setting the specular to 1 by default. I have the latest plugin verison. Is this correct?

I also noticed sometimes it will convert the roughness to OVER 1.0 as well. Then you touch the value at all it will shoot back down to 1.0.

Thanks!

I assume you are talking about Glossy materials? If I convert a Modo Material with a Specular Color or 0.5, 0.5, 0.5, the Specular pin in the resulting Octane Override is 0.5. Is this not happening for you?

Thanks for pointing this out. I will fix it in the next release.

I think most MODO users would consider the specular amount (especially in MODO 901's physical material) the corresponding channel to the 'specular' channel in a Glossy Octane material. It doesn't really make sense in the context of the Octane material though (since it's expecting a color not just a single float) so I wouldn't change anything - it's just a workflow thing. MODO users using Octane should think in terms of specular color and not specular amount when the material is converted.

Yup you are correct sorry. I could have sworn it use to be the amount though. My bad, you can leave it the way it is.

Thanks
