You may encounter anomalies such as Z-fighting, and incorrectly displayed or missing textures. If your scene was built exclusively for the earlier 3ds Max 'Render' feature it is possible that the model was not constructed using real world units. 'Lighting' and 'geometry' may also require dimensional adjustments.
plugin3D is the product name for a plug-in that enhances Autodesk 3ds max to provide superior quality real time 3D rendering and interactive user control.
