i am trying to get some specular shine on my loco model, but the results are not very good. I have tried before, got help from some members too, followed some related threads but i still have some issues.
Well i have used "TrainBumpSpecEnvMask.fx" and as per requirement used a diffuse texture with alpha, normalMap and again the diffuse map(without alpha, don't know if that matters) in the third slot, also used a 64x64 full black. Then set the MIPLoadBias to -2, and used 16,32 and 64 in the first slot of UV arguments, with no significant results.
Now the problem is the specular shine level does not seem to be affected even after changing the alpha channels color and also the specular texture seems pixelated. Below is a pic. So, can anyone please guide me how to get the required results. I need to cut down the specular level a bit more.
