Workflow: Revit to Max optimisation

Here are some good suggestions from Juan Carlos Arias and others for Revit > Max workflow:

Materials: All the geometry in the model should have a material previously assigned in Revit (especially families) in order to allow the use of the dropper tool in the material editor to select and change the material globally in Max.

UVW Mapping The UVW mapping of the geometry in max is generated by the work-plane in which the geometry was created in Revit. This is a very important factor to be considered in the creation of new families.

Geometry and number of faces/triangles: My advice in this matter is the proper use of worksets. For example, for the exterior renders we have been using three worksets: Shell, Core, and Structure (slabs, columns, and beams). In this way we ensure that only the geometry necessary for the creation of the exterior render is linked to Max.

Mental Ray: Distributed Bucket Rendering “DBR” is the optimal approach. Mental Ray allows you the use of up to 8 CPUs for a render of a single frame.

Enhancements to File Link and DWG Import Revit 2008 users can import projects into 3ds Max 9 Extension: Productivity Booster using the DWG format. This format encapsulates information about geometry, material, lighting, rendering properties, and cameras, streamlining project data exchange across multiple applications. This extension includes enhancements to DWG import performance, reliability, and ease of use.

Meanwhile, while we are trying to figure this workflow out Michael Ruiz a self confessed fan of Accurender is producing some great images inside Revit without the need to link to Max!.
