stripes Posted March 26, 2017 Share Posted March 26, 2017 how to create the effect where the trail created by motion blur is faded off instead of being solid through out. in renderman it's achieved with shutter effects, but i could not find anything similar in mantra. Please help. Quote Link to comment Share on other sites More sharing options...
protozoan Posted March 26, 2017 Share Posted March 26, 2017 No idea if there is some other method, but you can do it in your shaders.. on the Global variables in SHOP and MAT contexts there is a variable called "Time". It's not the global timeline position, but the shading time (from beginning to the end of the shutter). For example if you want to tint the front of your motion blur blue and the end red, this is where you get your bias from. You could use that to manipulate opacity (with all the unfortunate side effects this has). 1 Quote Link to comment Share on other sites More sharing options...
Guest tar Posted March 26, 2017 Share Posted March 26, 2017 Sounds like the same thing as Shutter Shape- add it via the Edit Parameter Interface. Quote Link to comment Share on other sites More sharing options...
