Advanced Member geo_n Posted November 21, 2022 Advanced Member Report Share Posted November 21, 2022 (edited) I always wondered, is this a bug or my misunderstanding of 3dc. I set texture workflow to roughness/metal and paint 0 roughness, 100 metal brush stroke. It's very shiny. 50% roughness layer opacity. It becomes blurry. It should be opposite right? 0% roughness layer opacity. This should actually be very shiny. 100% roughness and 0% metal layer opacity. It becomes shiny plastic. Again I think this is opposite.

Advanced Member geo_n Posted November 23, 2022 Author Advanced Member Report Share Posted November 23, 2022 Are you using the brush only or are you adjusting with the Layer? I'm only adjusting the layer opacity of roughness and metal. Gloss metal workflow is logical but roughness metal seems opposite to me. 1 Quote Link to comment Share on other sites More sharing options...
Carlosan Posted November 23, 2022 Report Share Posted November 23, 2022 ahhh sorry, brush only. you are right, roughness layer value is inverted. 3DC layers take white value as 100, pure black is 0. I dont know if its a bug or it is how 3DC works. Please contact support@3dcoat.com asking for this request. Thanks for point it up. Quote Link to comment Share on other sites More sharing options...

Member Thomas P. Posted January 8, 2023 Member Report Share Posted January 8, 2023 It should be inverted indeed. Not the first thing I encounter in 3DCoat that is in fact inverted and different from the way other apps handle it Quote Link to comment Share on other sites More sharing options...
Reputable Contributor Solution Fluffy Posted January 8, 2023 Reputable Contributor Solution Report Share Posted January 8, 2023 At first glance it seems like it should be inverted, but if you pop the Layers window out from its docked position and increase the width of the window you can see the full title of that setting isn't Roughness... ...it's actually Roughness Opacity and in that context it works exactly as you would expect it to, i.e. it controls the opacity of the roughness channel of the layer rather than the roughness value itself. 1 Quote Link to comment Share on other sites More sharing options...
