nocolorblue Posted September 10, 2008 Share Posted September 10, 2008 We're working with ESP Vision and texturing, but seeing as how this is more of a general Open GL / Vectorworks question hopefully you can assist us. We have an extruded grey rectangle with a texture applied to it, "Metal Alumunin Machined" creating a fence look. We'd like for light to be able to pass through the fence holes in Open GL 2.0, for use in ESP Vision. In Final Quality Renderworks the fence holes are open and look great, but in Open GL the fence hole are covered in grey and do not allow light to pass through. Is there a way to make this work with the texture? Extruding a rectangle and then subtracting the fence holes via duplicate array proved challenging and added too many geometric faces to our file.

Guest Frank Brault Posted September 10, 2008 Share Posted September 10, 2008 VectorWorks' OpenGL rendering currently does not support transparency shaders, the technology that can designate areas of a texture that are holes or transparent. Final Quality Rendering, a part of the RenderWorks product, does support this. hth, Quote Link to comment
cad@sggsa Posted September 10, 2008 Share Posted September 10, 2008 Also go see thread on Perforated Metal as to how to create a texture that will allow light to pass through it. http://techboard.nemetschek.net/ubbthreads/ubbthreads.php?ubb=showflat&Number=109114#Post109114 Quote Link to comment
