Hi, I have a problem to render Mantra with multi object type. Whening clicking render button from render view, it shows messages, 'generating scene' and 'Rendering(0.0%)'. However, actual rendering won't start. I am guessing problems are I try to merge different types of geos and render it as one Geo object. Is that really problem for Mantra???? here is test details;
1 - there are polygon, packed Geos, packed fragment, and (polysoup if unpacking ). Of course, NOT merging volumes
2 - This problem happens with turning on motion blur in Mantra. There is no problem with motion blur OFF.
3 - Mantra render's motion blur is ON, and delete attribute v (and w). Then rendering is working.
4 - surprisingly when changing order of merge-lines, rendering works somehow sometimes., strange !!
Thus, I have not found logic to fail render mantra. If you have similar issue and solution, let me know, thanks!
