supershape goes proSet

→ mainframe north is the developer of MASH for → Maya and, recently, independent from Maya, of the → proSets plugin. proSet takes one miniture manupulation you do to a polygon mesh and applies it to lots and lots of similar components of the same object. in the example below, which took ages to render, you see a so called superharmonics object, which by itself looks nice, but not very complex. i then applied two extrusions to two different vertices (=points on the object), one poking out and one pushing in. then i created a proSet for each of the two, played with the settings, especially random settings and logical conditions.

the renderings above, done in solid angle arnold, have only a single light source, namely a physical sky. no post processing in photoshop.

the plugin is certainly worth its few british pounds when you want to create extremely complex objects from simple things. the result is in many cases not precisely predictable, but who wants total control ,-)

Arnold rendering of MASH | color

von

complex procedure with fine result

this procedure is related to the problem of rendering Maya MASH Color node colours using Arnold. the workaround is complicated. pls don’t blame me. the tutorial where i demonstrate this is → here.

  • Create a MASH network from a Polygon object. Add a Color Node, play with the colour distribution.
  • Select the MASH_ReproMesh and assign a Shader of your choice, for example an Arnold Surface Shader. Set the colour to green.
  • In the ReproMesh-Attributes go to the MASH_ReproMeshShape tab und under Arnold → Export activate Export Vertex Colors.
  • Still in the ReproMesh Attribute editor, select the MASH_Repro tab and under → Output Attributes activate Color Per Vertex.
  • Display the Attribute editor of the shader you earlier assigned to the MASH_ReproMesh. You can do this by selecting the MASH network in the scene, then right mouse click and choose Material Attributes. It’s the green shader from earlier on.
  • Click on the checker icon next to Color and locate the aiUserDataColor node under the Arnold Utilities. Assign that node to the colour. It replaces the green from before.
  • Go to the MASH network node, select the Color tab, play with the colours – and render the scene with Arnold!

ian waters demonstrates the same procedure → here. he also pointed me to this tutorial of his which has nothing to do with the MASH Color Node, however: see → here.

more about → this discovery later. it’s basically a 3D scene with nothing but a pipe and several lights and cameras. you switch them on and off. i created mainly superellipse objects for these test renderings. each image took about 15 minutes to render using → arnold in → maya 2018.

second test rendering, same light

more or less the same objects, soft diffuse light setting

same scene, different light setup
