I'm discovering some inconsistencies in the way 3D Studio 4 creates flat mirror reflection maps when a shadow of a surface should be in the reflection map. The exercise consist of creating 4 cubes. Place 3 cubes adjacent to each other to form a right angle corner. Place the 4th cube on top of the corner cube. Place a spotlight in the scene and render the scene to see the shading and tone of the faces of the cube. I will upload a project file called chrcube.prj. Only 3 are visible. All surfaces of the cube are opaque except 2 veritcal faces. These have flat mirror automatic reflection maps. One of these reflective faces is on the top cube. This reflection map should pickup the shadow on the top surface of the adjacent cube, but usually no shadow shows up. How does 3D Studio deal with shadows in reflection maps? Thanks Wayne Leong, AIA Architect

>>How does 3D Studio deal with shadows in reflection maps? As well as possible. (We try our best.) Hopefully one of the product support guys can break it down for the QA dept at Autodesk. – G
