Looking around, I've seen people have issues with this. seeing as though no one else took the time to do this and I am sperated from my SD card and wii, I decided to do this.
In this tutorial I will be telling you how to add reflectors to your model import. incase you have no idea what this is, it's basically a shine effect that moves across the object as the camera moves.
Step 1. make sure that what you want relective is in a different object! if you don't do this, the reflector will effect things where you don't want it.
Step 2. After importing your model into brawl box, add a new material (you don't have to if there isn't anything that uses the texture that you don't want reflective) and add a new shader (<This isn't optional unless you really want everything reflective) and replace with
these materials and shadders Step 3. change the material so it uses the new shader.
Step 4. find a shine effect appropriate for the model shape. I recomend you make it an I8 texture.
Step 5. in the material, hit the plus button, and you should see something like this-
See how there are two branches? the top is the base texture, and the bottom one is the shine effect.
Step 6. Go into the objects, and make sure the polygons you want reflective use the reflective material
Step 7. Save and test. Good luck!
