Unwanted Light Reflection

[braddewald]

I have several vray plane lights set up in a scene. They are doing everything correctly. However, there is a square shaped reflection from one of the plane lights that is appearing on a large glass panel in the scene. I don't want to turn off reflections, because I need them elsewhere and excluding the glass panel from the light doesn't seem to do anything about the reflections. What is the solution?

Could you turn off the affect reflections option within the VRay light?

That's a good idea, but like I said I don't want to turn off reflections because the reflections of that light on the floor is crucial. I only want to get rid of its reflections on that one object in the scene.

[braddewald]

Do you think its impossible?

[erickdt]

If it is possible I don't know how :-/

select the object, go to properties and exclude it from reflections...or whatever u want. u can do the same in object vray properties.

did you try turning off 'affect specular' ?

[braddewald]

I need the reflection and specular to affect the rest of the scene, but not the glass panel. I guess I'll have to render the scene with affect reflections and affect specular turned both on and off and composite the two.

[dpcaltdcah]

instead of rendering the entire scene twice, could you just render that piece of glass separately? basically what you said but it would save you time...

Can't be done (GI engine and all), I haven't tried on the latest version of Vray, ill check later- dpcaltdcah is right. MR could do this.

can you just render a reflection pass on the glass and paint out the unwanted reflection?
