Download the tutorial blender file

This tutorial is based on the pointbased GI of the Pixie's documentation, so please read it beafore starting your own rendering.

Making the first pass (pointcloud bake file)

• You need to code a shader to generate the pointcloud file (see tutorial SHA_bakerad shader source code)
• Assign the shader to the objects and disable Raster orient, Cull hidden and Backface culling on the attribute editor on the same objects.
• Activate radio, area and add color Cs in the display channels render globals panel.

Make the second pass (Beauty pass)

• Code a shader to get the indirect lighting (via indirectdiffuse() shadeop)
• Add a pass in the render globals (passes slider at the top of the panel).
• Tweak the parameters of the renderer and shaders

Viewing the pointcloud file

You can use the Pixie's show command to see the baked pointcloud.
