Projectors... Question.

[bigmoe Whitfield]

So I'm working on a silly light thing for a water display I'm trying to put together,  I am including this video because I'm confused on something

 

it seems the projectors are leaving white boxes on the shiny surface and I can not make them go away...  is this just the way it is or am I missing something to make this happen?

All point lights including projectors cause glare on shiny surfaces. It seems with the PBR rendering the Blinn-Phong glare is massive compared to how it used to be: red is a point light, white is a projector (you can see the projector image on the surface). Material is black tint, white specular, 255 255 gloss/environ.

But you can circumvent it in two ways: turning gloss to 0 (or specular color to black) has this result:

Alternatively: use a PBR material; they will have glare, but it's much smaller, but also the spotlight texture won't be projected on the surface (1 metallic/0 roughness):

Thank you! I shall tinker and try these fixes!
