NEEDS HELP(3DS MAX)(ABOUT REFLECTION & REFRACTION OF CLEAR GLASS & MIRROR)

[IDC29]

How to remove those very sharp reflections of light on clear and reflective glass that is reflecting a wall? And it is only happening on walls? This is a sample of a clear glass that is refracting a wall. This sometimes happens when a clear or reflective glass is reflecting or refracting a wall.

Hi,

Without actually knowing what rendering engine you are using, here are some general tips:
Reduce the IOR of the glass to somewhere between 1.4 - 1.7.

Reduce the emissive value of the lights themselves.

Use a single sided reflective material.

Change the value of the light emitters to 'not be visible' in relections/refractions.

Lower the RGB value of the reflection/refraction on the glass material from pure white to something more grey.

Create a spectral / reflective element pass alongside the beauty pass and then use Photoshop Layer set to exclusion or subtract and then mask out the areas you want to reflect or not to reflect.
