JonathanGranskg Posted June 12, 2014 Share Posted June 12, 2014 I'm going to try to give some short answers your questions. Please note that I've never used MR or vray inside of Houdini, only prman, because frankly I haven't had the need to. Mantra is extremely powerful if you know how to handle it. I hope you don't have an apprentice license, because you can't use external renderers with them. 1-6. You need to use standalone mental ray, not maya's mental ray plugin. Same with Vray. 7-8. I assume Houdini volumes won't work. If you want to use Vray or MR, I think you're better off with alembics, vdbs etc to pull your data into maya/max from Houdini. 9. I'm guessing it will work decently, but for simulation work you're going to need something better than that. 10. http://www.sidefx.com/docs/houdini13.0/render/understanding Quote Link to comment Share on other sites More sharing options...

altbighead Posted June 12, 2014 Share Posted June 12, 2014 The reason you are not getting help is so few people use mental ray with houdini. Is there a reason you want to use Mental ray instead of Houdini own render Mantra? Quote Link to comment Share on other sites More sharing options...
mranosa Posted June 12, 2014 Author Share Posted June 12, 2014 yes , mantra is very slow !!! Is arnold able to render fluids , smokes and other dynamics ?? Quote Link to comment Share on other sites More sharing options...
JonathanGranskg Posted June 12, 2014 Share Posted June 12, 2014 (edited) yes , mantra is very slow !!! Is arnold able to render fluids , smokes and other dynamics ?? Saying both "mantra is very slow" and "I am very beginner noob" is making me believe that you haven't even tried learning Mantra. ¯\_(ツ)_/¯ But to answer your question, HtoA can render geometry and vdb-volumes. Edit: HtoA user guide: https://support.solidangle.com/display/AFHUG/Arnold+for+Houdini+User+Guide But then again HtoA is still in public (customers) beta.

Guest tar Posted June 12, 2014 Share Posted June 12, 2014 The best solution will be to learn Mantra instead of trying to trying to render to Vray and Mental d'lay. Many productions use Mantra and find it very good. Quote Link to comment Share on other sites More sharing options...
