Atom Posted August 23, 2015 Share Posted August 23, 2015 (edited) Hi All, I am working on a custom agent that takes the form of a bouncing ball. This is a single bone RIG that squashes and stretches. I have baked out my animation and the crowd simulation seems to be using everything just fine, however, when it comes to rendering I can not figure out how to enable motion blur for my custom agent. Motion blur is enabled in mantra, I have enabled Geometry Velocity Blur on my pre-baked geometry. I also added a Trail SOP to endure velocity was being calculated after the bone deform. I assume the bake feature supports baking of velocity data into our .bgeo and associated crowd files. When I compare the crowd_source node before and after the simulation I can see that the velocity is intact before the crowd solver. But when I render from the DOP import I get no motion blur even though the Geometry Spreadsheet clearly shows velocity values. Can Mantra do this? What additional setups do I need to perform to get my bouncy ball rig agent to render with motion blur? ap_ball_rig_bounce_in_place_1a.hipnc Edited August 23, 2015 by Atom Quote Link to comment Share on other sites More sharing options...
alksndr Posted August 23, 2015 Share Posted August 23, 2015 So you have geometry motion blur enabled on the pre baked but not on the crowdsource node, is there any reason for that? It seems to work fine when I add trail after the dop import and geometry blur on the crowdsource Quote Link to comment Share on other sites More sharing options...
Atom Posted August 24, 2015 Author Share Posted August 24, 2015 Thanks for mentioning that. I guess it makes sense that I have to enable the crowd_source node geometry motion blur. Quote Link to comment Share on other sites More sharing options...
kiryha Posted July 30, 2018 Share Posted July 30, 2018 I can't find how can I turn ON motion blur for crowd_source node geometry, nothing like that in UI. How can I turn on MB for my crowd? Quote Link to comment Share on other sites More sharing options...
Atom Posted July 30, 2018 Author Share Posted July 30, 2018 Try going up one level. crowd_source at the /obj level, Render tab and Sampling sub tab. Geometry Velocity Blur checkbox. Quote Link to comment Share on other sites More sharing options...
kiryha Posted July 30, 2018 Share Posted July 30, 2018 (edited) I have it turned ON, no MB thought... I have a trail node after my crowds sim set to calculate MB, it works for other animated geo but not for the crowds (I use animated FBXs as agents) but velocity is still = 0.

kiryha Posted July 31, 2018 Share Posted July 31, 2018 Yes, that's it, but after Unpack node my material stylesheets stop working! Quote Link to comment Share on other sites More sharing options...
kiryha Posted July 31, 2018 Share Posted July 31, 2018 (edited) Here is the scene E010_S040_003.hipnc Also, I can't understand why my TRAFFIC part does not render (if I delete stylesheets it renders again), but I will make a separate thread for that issue. dancing_01.fbx Edited July 31, 2018 by kiryha Quote Link to comment Share on other sites More sharing options...
