Ethan R. Posted May 28, 2015 Share Posted May 28, 2015 Hello all -- In need of some quick help. I'm trying to line up a bunch of custom gobos on a wall that have a pattern. I'm trying to show the client what that pattern will look like. When I use the "Spotlight>Visualization>Create Gobo" Tool - it creates the Renderworks Texture --- Is this texture photometrically accurate based upon the gobo file? I have included a screenshot and the PNG. The lights in question are about 34-44' from the wall They will be vl4000 right now they are drawn in as Mac700s - because for some reason the VL symbol was not projecting gobos in RenderWorks. Field / Beam angle is 35º all around. Any help (especially quick help) appreciated !! thank you Ethan Quote Link to comment
Ethan R. Posted May 28, 2015 Author Share Posted May 28, 2015 FYI all - via VectorWorks Support: ____ The rendering will get you close but it’s not exact. We place the geometry at a distance from the light source and utilize the spread of the light to project the size. Since the location of the gobo varies in the optical path of the real lighting fixture we can’t be 100% accurate. We recommend to send the details to the gobo manufacturer and let them confirm the image size based on the fixture and the throw distances. ____ Quote Link to comment
