Optimising render?

[dynamoanders]

Hi guys.

I´m trying out some lightning, shading and rendering in Mantra.

Here´s a scene I did, doing some test renderings with Motion Blur and DoF, also added some displacement and blurred reflections on the shaders. Lightning was done with arealights.

First I tried to do it with the Micropolygon renderer, but then I had to crank the sampling quality on the arealights way up, then I switched to PBR and that did not need as many sampling quality in the area lights

I tried to do a similar setup that I would do in Maya and Vray, but maybe I´m doing something wrong here? Maybe there´s a better way of lightning or rendering?

What do you think? Does anyone have any suggestions?

Thanks

Hi Anders,

what's worng with your rendering, motion blur working, dof working, displ working, it seems ok to me for a test. Keep in mind that area lights works best with PBR! There are some free real good tutorials here https://vimeo.com/user2030228 from Peter Quint in order to understand how houdini works, he covers everything you need for a basic rendering, shaders, render engines, motion blur, dof, passes etc.

Hi cparliaros.

Thanks for your reply, there is nothing wrong with my renders, but I was more wondering if there is some way to optimise the renders (if you could shave off one minute from each render, that would make a big impact if there are hundreds of frames etc...). Any suggestions would be good :-).

I have already watched Peter´s tutorials, which are awsome by the way, and am quite familiar with how you render in Houdini and Mantra (micropylogon, PBR, passes etc), but I am trying to up my production quality, and was wondering if there´s a way to optimise my renders?

With this resolution and these settings, I´m getting around 2 1/2 minute a frame (on a pentium I7), and I where wondering if there´s some how optimise it? I know that it is expensive with arealights, displacement, MB and DoF, but that´s why I wanted to test it out.

Maybe I can have the keylight as an arealight and spotlights as the rimlight and fillights? I just trying to learn Mantra, shading and rendering, and how to get the most speed out of it.

Thanks
