i am having a problem with light being real intense beneath a glasslike bottle i modeled, but anywhere else in the scene the light is subtle and soft. i am using simply caustics (mentalRay) and no globalillum, or final render. i have one spotlight in the scene. but my bottle just glows, and shines like crazy at its base, but this lessens tremendously if i lift the bottle from the surface. its like there is some kind of intensity increase that happens when the two come near each other.....why? my floor is a simple blinn that has no reflectivity, and whose diffuse and ambient are also low. everywhere else but under my bottle the light is subtle and soft.
