Most people who use Maya, Nuke, etc will disable UAC because of batch render issues. In Windows 8.1/10/Server it will give you some errors where you cannot run native Windows app with the error "App can't open with built in administrator account".

The default geo subdiv settings in V-Ray are a bit strange. Perhaps they are good for fine displacement but in general for subdividing they are a bit high. Read on for some suggestions.

It can be complex to have a source plate that is matchmoved and then have a retime or timewarp on the material. This can be done quote easy like this...

Need to Search and Replace a lot of textures? You can execute a MEL script for that. In below example make sure to replace the SEARCH and REPLACE sections. If you use \ (backslash) make sure to make them double \\ so they parse correctly.

OK, so you get funky speckles/noise when rendering without GI but with high samples in V-Ray for Maya? Well, it turns out that if you enable Brute Force GI with Depth and Samples set to 1 (so it won't change the look or rendertime) the noise pretty much disappears!

When you make title elements or other motion graphic elements for Premiere you often end up with grey edges because most of us render out these elements als PREMULT. But, if you render it as UNPREMULT then the edges become clean. The RGB channels will look weird, but when placed with the Alpha it looks good.

So when you want to make a quick preview render using the Hardware 2.0 renderer for some reason you get black objects. Check your viewport (set to Hardware 2.0) and press '5' everything looks good? Press '7' do you see the black objects? Check... If this is the case set the Render Lights to 'Default' instead of 'All'

You get work back from remote workers and get this message?
To list them: ls -type unknown;
To actually remove the unknown nodes: delete `ls -type unknown`;

To clean up yout namespaces after importing/referencing objects try this:

After your objects are imported paste the following line into the script editor –

namespace -mv "insert_namespace_here" ":" -force;

Replace insert_namespace_here with the namespace of your imported objects. ie for an object that is named part1:Cylinder02 use the following –

namespace -mv "part1" ":" -force;
