frading Posted September 17, 2003 Share Posted September 17, 2003 HI, I am trying to achieve a few sound effects and I need to use the accoustic CHOP, so that I can have a geometry occluding the sound coming from a source. It works well when I set the collision detection to bounding box, or to primitive bbox, but it seems not to work at all if I set it to object geometry...Is this a bug?

edward Posted September 17, 2003 Share Posted September 17, 2003 Have you read the section "The 3D Spatial Audio System" under the "03 - Objects" pdf chapter? Specifically, section 1.4 on "Obstacle Occlusion". Quote Link to comment Share on other sites More sharing options...
frading Posted September 17, 2003 Author Share Posted September 17, 2003 yes I did. And I came with a setup that works really fine when the collision detection parameter of my accoustic chop is set to bbox or prim bbox. But I would really like it to works with "object geometry". And for testing purpose, my actual geometry is a simple box, so the results should be exactly the same, no? Quote Link to comment Share on other sites More sharing options...
edward Posted September 18, 2003 Share Posted September 18, 2003 Did you do the sound material part? Other than that, I have no clue. Quote Link to comment Share on other sites More sharing options...
frading Posted September 18, 2003 Author Share Posted September 18, 2003 Could you please have a look at this sample file? I tried to name the operators as properly as possible so that you can easily understand them. all chops are under /ch/ch1 And my actual problem is that everything works fine if the coldetect parameter of /ch/ch1/spatial_chop is set to "bbox". But if it is set to "objgeo", it does not seem to work anymore. So, a little help would be really be appreciated ( and I assume I have read everything about it in the docs, but I may have missed something ) accoustic_CHOP.hipnc Quote Link to comment Share on other sites More sharing options...
edward Posted September 19, 2003 Share Posted September 19, 2003 Yep, this looks like an oversight to me. I'd simply stick to using primitive bbox. If you post on the early access forum, maybe someone will log a bug for it. Quote Link to comment Share on other sites More sharing options...
frading Posted September 19, 2003 Author Share Posted September 19, 2003 ok, I ll do that. And thx a lot for your time! Quote Link to comment Share on other sites More sharing options...
