I made a 3D drawing of a subway station using AutoCAD R13 made from several solid boxes unioned together and imported it into 3D Studio to be rendered. I ran PC Paintbrush program to draw a tiled wall to be used as material to be applied to the subway station's walls but I ran into problems. I chosed the material, assigned the material to faces, scaled the mapping icon, and applied the icon to the faces. I tried detaching the faces but it didn't work. Jeffrey.

Might be interesting to check to see which direction the face normals are pointed in. Assuming that you do not have Yost Disk #7, Have you tried rendering the objects with default materials to see if the faces exist? If so next you might try Surface/Mapping/Adjust/Bitmap Fit and then use the center command to locate the map icon. If that still doesn't work you might try scaling the map icon drasticly large and small. Make sure "face map" is not selected in the Materials Editor. Check that you have assigned "Tile" in your Mapping Parameters in the Materials Editor. Hope some of this helps <g>. -Lee

Jeff, Try selecting the faces, and detaching them into an object. You now have two choices 1) make the mapping coordinates the size of the object, and use the tile settings to adjust how the image repeats along the x and y axes. TIP: instead of repeating this for every adjacent wall, keep the mapping coordinates size and tiling settings the same, and rotate the coordinates flat to the adjacent walls, this ensures that the tile lines will line up perfectly. 2)scale the mapping coordinates to the size you want each tile to appear and apply it. Use bitmap fit to get the proportions of the mapping coordinates correct. When using this method the tile settings have to be x=1, y=1. Check your image to be sure that it is exactly the size you want – no extra balck border or space around it. Try "FORCE TWO SIDED" on the render dialogue box.

Dear Kevin, I made a new drawing of the subway station made from several solid boxes but didn't combine them into one object and it worked. I made three bitmaps and applied them to walls and platform. Jeffrey.
