He hasn't really done anything yet except get the car imported into 3DS Max š
Okay, so, here's a set of material settings that I use. Do you need help ripping the textures for the Solstice with Forza Studio? If so, I can talk you through that, but it's really simple. (Go to Textures tab -> click the texture you want -> right click -> export as PNG; repeat for all textures you need.)
Spoiler: Okay, so:
Open the MAX scene included in this file, and go to "Merge" and merge in your whole car you imported in another Max scene.
You should see a button with four circles on it (it's in the top right corner of the window). Click on that. You should get a dialog with all of the material settings in it.
You may notice that some of them say "YOURCAR" at the end of them. Change "YOURCAR" to "Solstice" or whatever (this isn't actually that important, but it helps you keep track if you're working with multiple Forza sources at once, like I tend to end up doing).
Then, copy in the Solstice's LOD0 textures (nodamage_lod0, interior_lod0, lights_lod0, wheel_lod0) and rename them to "Solstice_nodamage_lod0" etc.
Go into the "LightsInner_YOURCAR" (now "LightsInner_Solstice") material and click on the boxes for the "GTR_lights_lod0.png" texture. You should get a window that looks like this.
Change these to "Solstice_lights_lod0" (one of your files) by clicking on the file name and path button. Also make sure that the green settings are marked the way that they are shown in the picture - this will be important for things like glass. Repeat this with all the bitmaps that have "GTR_" file names.
Now - you can click on a material and select a part, and click on the third button on the long row of buttons in that dialog (the arrow pointing from a sphere to a box) to assign materials to your car.
This may be a little slow. If you can figure out how, you can speed it up by using the Selection Floater (Tools -> "Selection Floater...") and selecting all "Body" parts to put the "Paint" material on, all the "interior" parts to put the "Interior_Basic" material on, etc.
Let me know if you get stuck!
EDIT: Oh, whoops. He posted that whole update in the time it took for me to type this up. xD
But, yes, do smoothing. (I wouldn't recommend auto smoothing. Just put one smoothing group - like group 1 - on everything. Only use auto smooth if it screws up the door seams or something.)
