Hi,
You don't really need to see your textures in 3DSMax; they will still show up after export to FS. But if you want them displayed, see below.
If you imported it via a 3DS file:
For anything that needs to be smoothed that looks blocky:
1. Select that part.
2. Add an Edit Mesh modifier from the stack at the right.
3. Click the little black + sign next to Edit Mesh
4. Choose Vertex sub mode.
5. Edit/Select All
6. Set the number next to the Weld button (on the right side of the screen) to 0.005
7. Press the Weld button.
8. Click the screen to deselect the vertices
9. Choose Polygon sub mode.
10. Click the Auto Smooth button near the bottom of the right side (scroll down).
You can do this with multiple parts selected to save time, but if you do make sure to right click the stack and choose Collapse All when finished, so you don't confuse 3DSMax later.
First you will need to get your textures into a format that 3DSMax can read (24 bit BMP and TGA are two common formats). I paste a set of them into the same folder I saved the 3DS file (and eventually the 3DSMax files), and convert them if necessary.
To get your textures to show up on the model in 3DSMax:
1. Click the red ball button along the top (Material Editor)
2. Click the Pick button.
3. Click on a polygon that is textured.
4. In the material that results, click the little blue and white checkered box.
5. The texture should now display on your model.
6. If not, go to the Maps section of the material window, and check the name of the texture.
7. If it is ~ with some letters after it, click that name.
8. In the box that results, click the wide button with that name on it.
9. In the box that results, double click the black Bitmap box.
10. Browse to the folder with your textures in it, and choose it.
11. If your model has more textures, repeat 2-10 until your model is completely textured again.
