usually maya creates a folder for you with diffrent images in it if you have AOV on, AOV = when rendering an image it will save diffrent passes (example. the reflection as one image, the specular as one image and so on...) look at your render settings to make sure you dont have this enabled. im not sure what its called in Vray. if you disable AOV you will get one beauty rendered image.

this is all i can think of, goodluck
