[C4D] Resolved Feature Requests / Re: layered material : blending modes ?

« on: 2017-03-29, 10:43:22 »

thx for your replies .

I don't understand. Maybe the results are more simple without layered material. What do you want to obtain exactly?

well , my simple example was just to show that we can't "add" effects in the current layer system in a non destructive way . Of course my example could be done in one mat , but when you'll need to build several reflexion/specular layers over the diffuse(s) layer(s) etc that's the goal . When you say we break the 'energy conservation' by adding a layer instead of mixing it .. as we can add it in a simple material , this has no sense for me sorry ( or this means that a simple material with a reflexion added inside is wrong so ?  )

Blender Cycles is a pathtracing engine if I'm not wrong too  ( sorry I'm not an expert with that so maybe I 'm saying mistakes) , and can allow building shaders by mixing and adding 'layers' ( "horisontal layers" / nodes ) .

( In fact I'm dropping Octane because of this lack of possibilities :) ( and still no hair shaders too ) . So I look arround the other render engine to see how they work and their limitations ;) . )
thx

Hi Houska :) . thank you for your replies .

I checked your example and that's the problem I have : your diffuse color is mixed with the black 'color' of your glossy mat so at the end you have lost your real diffuse color as you push it toward the black.
So we have to counter this by "pushing up" the diffuse color strengh to get it at the right value at the end . That's why mixing mode are importants ( mix/add/multiply etc ) .
Here some example of Blender cycles render engine : there is a 'Mix shader' (like your layer shader is working , and same for Octane etc )  but there is a 'Add shader' which offers this 'non-destructive' mode of adding B&W glossy effects over a diffuse layer as here for example : ( the 'Cycles_Reflexion added over diffuse.jpg' is the behavior I'd look for ..a non destructive way of adding layers and keeping the init color values :) ... the best behavior would be to have a strengh/amount slider on the Add mode too of course ( here the Cycles Add Shader has no strengh control so you have to make it outside this node off course)  )

Hi all , I'm new with Corona render , and wanted to give a try building some layered materials , but I don't understand how it can works without blending mode ( adding a black glossy mat on the top for example to get the reflexion coating etc ) . is it planned to make it work with blending modes in the future ? ( normal, multiply, add etc )

and by the way , if I'm not wrong , in Octane for example , when you have a full opacity on a material , you can still see the reflexion effect .. here opacity seems to kill the reflexion so hard to get a "reflexion only" material .

thank you
