V-Ray Limitations At this time of writing, V-Ray GPU doesn’t render the Pref pass out using known techniques. So meanwhile, you’d have to use V-Ray CPU instead. Good thing, Pworld renders perfectly fine in V-Ray GPU. Nuke Crashes When Using Pref Information In Nuke, we can use the World Position Texture Projection node to project […]
A quick and dirty way to load an .obj sequence in Maya and have each geometry’s visibility automatically keyed to show up at the frame they are supposed to show up. Wrote this script as an experiment, but don’t have time to make a UI, so I just commented on the two variables to change […]
Quick MEL script to quickly re-connect existing texture connections from one slot to another within multiple materials. To use, alter the script to determine the attributes to connect/disconnect, then select multiples materials and run the script. As defaults, the script is set to get the first input node it can find, its outColor attribute, re-connect […]
One way to export multiple geometries from Houdini to Maya and preserve the geometry separation is to make sure that the primitives have individual @name attributes before using the Merge SOP. Thereafter, ensure that the ROP Alembic Output has ‘Partition Mode’ set to “Use Shape Node Component of Path Attribute Value”, and ‘Partition Attribute’ set […]
Hey! I’m an old school CG artist from the days of CPU rendering and depth pass and zDefocus, and only recently got over the psychological barrier of doing in-camera DOF. My conclusion – it’s liberating. Of course, GPU render engines like RedShift is the real deal for this kind of workflow. But for now, for […]
It’s very time-consuming to manually create many ramp entries in Maya’s ramp node, so I wrote a little script. This simple function can be useful to create a procedural circular brushed metal texture where we want a hundred alternating colors. //Author: Ronald Fong //Date: 03 June 2018 global proc rf_zebraRamp(int $count) { $ramp = `ls […]
Happy to be invited back to SIDM, as an Alumni, for the part of the EAE Parents’ Seminar, to share my student experience and how it has prepared me for the industry. The learning environment is great and it’s encouraging to see some hardworking students on a Saturday! The school now sports an awesome impressive […]
Houdini’s alembic import module, by default installation, doesn’t work well with alembic files on the network. You’ll notice that you can only load .abc files on your local drive, and not those on the network drive. This can be resolved by adding this line to the houdini.env files: HOUDINI_ACCESS_METHOD = 2 In case you’re wondering […]
Problem: The color node’s ‘Use Velocity’ is useful to create interesting effects. It works just fine with all other nodes with the MASH system, with the except the new Maya 2018’s MASH Dynamics node. Solution (Part I): The nice guy at Mainframe (North) explained that this was likely due to Dynamics ‘taking over’ the position […]
Here’s a quick MEL wiggle expression for Maya’s transformation channels. This is similar to After Effects’ wiggle() expression. Step 1. Go to Channelbox > Edit > Expressions… Step 2. Paste the following Step 3. Adjust Frequency, Amplitude and per axis frequency Variant to liking Note: By default, the translate Y and Z frequency has […]
