#RENDERMAN 22 RELEASE DATE MANUAL#

Complete a three-point lighting setup.Paint maps to render your mesh as closely to your art concept as you can.Use Mari with a PTEX workflow to paint surface textures.(I actually found triangles are working well now – I would recommend them, as you may have issues reducing and keeping clean quads from the scans). Export to obj again for mesh setup in Mari. Quadrangulate for better Ptex workflow.I also smoothed it, ran some mesh clean-up options to be sure, and also switched the normals to per face and did some other options such as average and soften-edge to smooth the appearance a bit more under the normal display to counter some odd effects of the normals from the reduced scanned mesh.) (I took my example mesh to 20k polys with the guarantee-count option. You may find you have the best luck / computer speed by reducing fairly significantly.

Reduce and/or smooth model in Maya, if desired (perhaps test with a few quick renders before deciding and passing on to Mari).Rotate by 270-degrees on X-axis for convenience. (Maya 2018 can directly import stl, so skip MeshLab). Use MeshLab or other to convert from stl to obj format.Base this and communicate it through choice of reference photos, a paint over, or other concept paintings. Choose an art direction (realistic or stylized).Choose a model with a face from Scan the World.Look for the Ptex section and enable `emit face IDs.’ Objectives: Choose your mesh under the attribute editor, look for the RenderMan options under the shape node tab for your mesh. Connect the output (such as combined RGB) from the PxrPtexture node (where you point the file option to your. Make sure you have a Pixar light in your scene (can change the viewport in your working panel to use RenderMan in 22). RenderMan 22 Note: Add a PxrPtexture node and a PxrSurface node under Hypershade in Maya. Under Hypershade, connect a “PxrPtexture” output (such as combined RGB) to the input (such as diffuse color) on your PxrSurface node that you wish your painted channel to control. Make sure to attach to your model by selecting and choosing the attach button. Add these two attributes: “Bake Context” and “Ptex Face Offset”. RenderMan 21 Note: Choose RenderMan->Advanced RenderMan Controls (from the main RenderMan menu added to the Maya menu bar when the RenderMan for Maya plug-in is loaded) Under the window that appears, choose View->Geometric Settings. Bolt was the first film completely textured with a Ptex workflow at Walt Disney Animation where Ptex was developed. Read over the Eurographics paper that introduced Ptex in 2008.

(The trend for path-tracing has grown in recent years, and we’ll explore this more as well as discuss other rendering solutions.) The most recent RenderMan was drastically re-architected (RIS) in recent years, however, to use path-tracing with the flexible choice for integrators and BxDFs, and it is one of the premier path-tracing production renderers in use currently in feature animation and VFX. RenderMan as a name dates back decades to Pixar’s early developments for rendering using the REYES algorithm, and the technology has been used for a myriad of films in the time since. Mari was originally developed at Weta Digital with the goal of painting large-scale, high-resolution texture maps for feature-VFX assets.

Ptex was developed at Disney in an effort to surface complex models without the need for manual texture layout. Assignment 06 - Ptex, Mari, RenderMan (Updated) įor this assignment the goal is to switch to a production renderer (RenderMan RIS – preferably version 22), use Ptex as an alternative form of texture mapping, try Mari for texture painting, and practice a bit of lighting (which heavily impacts rendering and shading).
