Systemd services and resource limits

We made the move to CentOS 7 and I switched out all init.d scripts with systemd services. Yesterday I noticed we started getting errors on our render farm for huge scenes which required loading of thousands of files: V-Ray warning: Could not load mesh file … One hint that this wasn’t due to scene misconfiguration was that the initial ~1000 vrmeshes were loaded successfully, and after that no other vrmesh file could be loaded....

3D rendering in the Google Cloud

Guest blogging for Google! As a small design and visualization studio, we focus on creating beautiful 3D imagery – be it high-resolution product images or TV commercials. To successfully do this, we need to ensure we have access to enough rendering power, and at times, we find ourselves in a situation where our in-house render farm’s capacity isn’t cutting it. That’s where Google Compute Engine comes in. Read more over at the Google Cloud Platform blog....

Generating a spherical HDR image with V-Ray for Maya

Create a camera and place it where your objects resides which the HDR dome should affect. Add the V-Ray attribute “Camera Settings” to the camera and scroll down to “Extra Attributes” in the Attribute Editor. Here, set Type to “Spherical”. Override the FOV and set it to 360 degrees. In the render settings, set the output image format to .hdr, turn subpixel mapping off and do not clamp output. Render with width/height ratio 2:1, e....

Getting V-Ray to render "Nuke-style" Z-depth

Out of the box, V-Ray for Maya does not render Z-depth the same way Nuke does. Here’s a quick fix for that (not applicable for most DOF plugins). Problem When “3D-comping” something into an already 3D rendered image using a V-Ray generated Z-depth AOV to describe the depth, Nuke’s ZSlice will not work very well. The reason behind this is that Nuke internally computes Z depth from the camera plane and V-Ray computes Z depth from the camera point....

V-Ray for Maya

Running V-Ray for Maya in a production environment has its quirks. I have collected some bits and pieces off the Chaos Group forum and assembled it all here. Table of contents Arbitrary location installation Arbitrary location configuration Python launch script and MEL sourcing Launching the V-Ray render slave from the arbitrary location Arbitrary location installation Choose a server location for all your builds and create a folder for the specific build you are installing....

Turning your renders up to 11

An interview with me on our cloud rendering solutions is now published over at CGSociety. “We need to make sure that we’re working with the best technology, as some of our projects can be very render intensive,” he begins. “But our motto is to spend time focusing on the creative side of building beautiful images, and let the machines do the hard work.” Check it out here.
