Gobos???

Hi All,

 

I am new to this forum. 

 

I am an event designer in Scotland and use sketch-up and irender nxt to concept visuals for clients. 

 

In the event industry, we commonly use Gobos - these are metal or glass discs that have a design cut into them.  When put in a spot light/profile between the lenses and the lamp, the result is a projected image of the said design.

 

Has anyone go an idea of how I can create gobos for use in Irender.

 

If this is something that could be created, it would become a rival to a program by the name of WYSIWYG

 

I look forward to your responses

 

Graeme

    These work in IRender nXt - just make the spot light itself very small (in size) to make sharp shadows.

    For the image below, the spot light is 1" wide (The 3' visual beam appears larger, but is just for positioning. It is not part of the actual light)

    I placed the spotlight in a cylinder (semi-transparent in the SketchUp X-ray view so you can see it better) in a cylinder with an alpha-transparent image on the end face of the cylinder (The SketchUp Fence material)

    Is this the effect you are looking for?
