Re: Tip-Zero Effort Beveling for normal maps
in maya 2009, what i do is set the bump map in the slot provided by the mia_roundcorners node and then change the bump mode. heres what the bump mode does according to the docs. bump_mode defines the coordinate space of the bump_vector, as well as that of the return value of the shader itself (which is also a vector), and… -
Re: Tip-Zero Effort Beveling for normal maps
There's a Rounded_Corners node under Nodes>Bump. Plug that into any material's bump port, and change the Bump mode to one of the "Set Bump Vector"s of your choice. Works like a charm. -
Re: Tip-Zero Effort Beveling for normal maps
I've never really worked with mental ray before, so I looked for a tutorial on mia_roundcorners. This one covers using the node with maya materials and mental ray materials: [ame] http://www.youtube.com/watch?v=lEnsEGlFsBQ[/ame] This one uses a slightly different method for using it with MR materials:… -

Re: Tip-Zero Effort Beveling for normal maps
Plug a bump/round corners node into your materials bump channel -
Re: Tip-Zero Effort Beveling for normal maps
Awesome. I just tried plugging a Rounder_Corners node into the Material (Softimage) and used Rendermap to capture the normals, and it created the same effect. This might come in handy. -
Re: Tip-Zero Effort Beveling for normal maps
For you Maya users its available in mia_material. You can also unlock the node in the mia and use it in the bump slot of any material. I just wish they'd made a version for the scanline renderer Another trick to be aware of is you can use multiple versions of the material with different radii. -
Re: Tip-Zero Effort Beveling for normal maps
cryrid, thank you very much for your detailed explanation on rounded corners baking! P.S. Tried today to bake round corners in SI 2011 and got flat result :( ( Used all your advices (tangents and binormals)... May be it fails in 2011 because there's no "round corners" node - only "round_corners_mia" ? -
Re: Tip-Zero Effort Beveling for normal maps
So in Maya this is working quite decently. But there are cases when mia_roundcorners does not create acceptable solutions. Take for example two convex neighbouring faces - if their angle exceeds 90° degree there won't be any satisfying normal modifications. Instead you'll get the shading of the underlying low poly… -
Re: Tip-Zero Effort Beveling for normal maps
Finally succeeded to bake the mia_round_corner effect into normal map :) As you can see there are 2 remaining problems: 1/ minor artifacts on the cap edge of the cylinder which I can't solve...Edge padding that I need to change maybe ? 2/ As Polynaught stated : "Take for example two convex neighbouring faces - if their…
