This is because the open EXR don’t have any type of compression on them. We received multiple requests for adding compression on the EXR files Autodesk has placed this product issue on development's product modification schedule.
For the Final gather contribution behind glass containers, you will need to adjust the MAX Trace Depth This option is similar to -trace_depth but applies only to finalgather rays. The defaults are all 0, which prevents final gather rays from spawning sub-rays. This means that indirect illumination computed by final gathering cannot pass through glass.
Note: This is not compatible with mental ray 3.1 and earlier, which used the trace depth (which defaults to 2 2 4) for final gathering.
When using an object that has displacement map. and adding it to a Render Layer using the Ambient Occlusion preset, the object lose its displacements.
Simply copy the shading network of your displacement add an mib_amb_occ texture to the incandescence of the new shader Adjust the mib_amb_occ as desired repeat the above step for any other displacement shaders Connect the same mib_amb_occ to the rest of the shaders
First things first, thanks to all of you who replied to my survey a few weeks back. Happily, the feedback was mostly positive.
All things considered, there will be a couple of minor tweaks to the layout of the blog.
Nothing more than a spring clean. I reshuffled the Categories and deleted the empty ones. I've added links to several self-help pages in an effort to turn the blog into a sort of self-help dashboard. And in that spirit, I'll write more about what it is we spend our time doing here in product support.
Also, we shall do our very best to post on a wider variety of topics. That said, Ash's specialty is mental ray and I'm always looking for ways to make my life easier, so expect more scripting and rigging ideas...
And it's about time I looked into Python a bit more too.
The best suggestion we had was for a user submitted "question of the week". I like this idea and will follow up shortly. While trying to steer Maya users to post their questions where they're likely to receive an answer - the Area, Subscription Centre, Ask Autodesk - I don't see why we can't publicly discuss certain topics through the blog. So if you'd like to raise a question, please send it to me:
firstname.lastname@example.org (make the title something nice, like "mayastation question of the week")
Depending on the response, I'll choose questions that are likely to impact a wide range of users - for the benefit of the silent majority, and perhaps even our software developers!
