David Lemelin Posted May 5, 2015 Share Posted May 5, 2015 Hi guys, i have an illustration I am working on that involves a great deal of small fairy lights in curtains and various displays. I can't imagine creating several hundered emitters in a scene and what that will mean to render speeds, but I do want to convey the look with a reasonable amount of accuracy. My initial thought is to create an emitter material that features some form of opacity mask, such that I could apply it to a basic shape and create a single emitter that shows as multiple points of light. I shudder to imagine the processor overhead if I need to hammer out hundereds of individual polys in FormZ and then run all that through Maxwell. Does any one have any tips or thoughts? Thanks David Link to comment Share on other sites More sharing options...
Des Posted May 6, 2015 Share Posted May 6, 2015 You could try this material in the Maxwell resource page, even if it gives you a start for editing.. http://resources.maxwellrender.com/search.php#page=1&mode=1&search=lights&v1=0&v2=0&tipo= Des Link to comment Share on other sites More sharing options...
pylon Posted May 6, 2015 Share Posted May 6, 2015 Here is an example with a custom emitter MXM: The material is mapped to a simple plane. The HDRI was made in photoshop (32-BPC image, saved in 'Radiance' format.) In MXED, created a new material with an Emitter layer, with Emission set to the HDRI. The emitter's opacity mask is also mapped with the HDRI, to only the glowing areas show and the background is transparent. The glow around the dots achieved by enabling Simulens Diffraction in the finish render. Hope this helps. MXM and HDRI: fairy_test.zip Link to comment Share on other sites More sharing options...
pylon Posted May 6, 2015 Share Posted May 6, 2015 Alternatively, you could emitter-map a bunch of icosahedrons or low-level geodesic spheres. Link to comment Share on other sites More sharing options...
