OTOY Forums

Hi there,
I'm trying to assess if Otoy would reduce render time for architectural type renderings.
I have a very simple scene that has a plane, a couple teapots and an OctaneDayLight. The meshes have simple diffuse and specular materials with nothing changed but the color.

In the OctaneRender viewport, the rendering is nearly instant. However, when I press render, each frame on this simple animation is taking about a minute. At this speed, it's not really an advantage over using Mental Ray or some other competing program. I can only imagine that render time would increase as geometric complexity, multiple light sources, reflections and transparencies are added.

So, I must be doing something wrong. Seems straightforward enough.

Some basic specs:

3Ds Max 2014
32GB of RAM
Win 7 64 bit
NVIDIA GeForce GTX 670

Thanks.

I imagine that resolution would be a factor, but the test render is 800x600 which looks like what my octanerender viewport is.

Just to continue the test I dropped in a 3+ million poly zbrush mesh, and set an emitter to spew glass teapots in front of it. Render time was 8 minutes per frame. Likely faster than mental ray, but still quite a bit slower than the octanerender viewport.
thanks.

How many samples have you set?

Hi Karba,
Thanks for your reply. I left everything at default in render settings. If you're talking about maxsamples, it appears to have been set to 16000. That seems like a big number for sure!

Just for kicks, I've now turned that down to 1000 as a test. The same frame that rendered at about 8 minutes, now rendered in 1 minute. Of course, it was grainier, but at least I understand now where to look to manage the tradeoff.

Thanks!

I guess putting my settings to 100 000 max samples is a bit overkill then? lol
