Decided to try out rendering VDBs (volumetric containers) with Redshift as I found some online that I could download and experiment with. Eventually I need to learn Houdini to make my own smoke/fog elements as it seems far easier to do it there than with Maya Fluids… but for now, these are cool to have. Crazy how fast they render with Redshift as not that long ago rendering such things required a lot of patience. Buildings are from Kitbash3D who kindly asked if I’d like to play with their library for an upcoming demo. :) Using model libraries seems to be becoming a lot more popular lately which is a sensible progression I suppose. Since the early days of 3D everyone was happy to use purchased texture libraries… yet it was also easier to find high quality textures than models. These days with photogrammetry that has changed and it’s fun to have access to more assets. Becomes more like playing with legos as the end result is more an exercise in composition, lighting, materials, rendering and grading. Feels a bit like cheating, but I suppose a photographer isn’t criticized for not having sculpted everything that is in front of the camera. Seems like such work in 3D is an evolving hybrid… and definitely still a little harder than snapping a photo. Unless you’re Gregory Credson. :P
Just started using MASH in Maya 2017 this week and it is really cool! While it is marketed as being a Motion Graphics tool, it is ultimately an amazingly powerful object instancer/duplicator. This is my first test with it and basically... I don't think I'll be needing to use EITHER particle instancing OR the SPpaint3D script anymore. Which is awesome. i.e. MASH has geo paint built-in which is ultimately way more powerful than SPpaint, while its instancing tools skip the need for writing particle expressions on custom attributes, caching, runups, etc. Another big plus is that instanced objects on a surface, by default, orient themselves to the surface normals, which is why I used grass for my first test. While this was doable with particle instancing, it required a hefty and slow to calculate expression. Anyhow... going to be a big time saver while making the process much more fun!
I've also been building a library of World Machine assets that are ready to import from a Maya shelf, primarily for when I need Mountains/etc in the background. This image was the result of importing one, adding some Megascan materials (which I also have on a shelf ready to go), importing my water plane (on a shelf as well) and... quick island image!
Been playing with Maya, World Machine, Redshift, etc as I get ready for demos in Melbourne and Sydney, Australia, next month at Gnomon Live. The goal is to give a variety of tips and workflow ideas as I create a scene which will include some things made on the fly while populating the scene with elements from my library. Hopefully I can share something useful to those who attend! Below are some images that I've added to the 3D Development section as these aren't planned images, just things made while messing around. The character models are the only things I didn't make, but downloaded from RenderPeople.... although I did swap the heads on a couple with ZBrush sculpts. :)
New personal work to test out Redshift with a relatively heavy scene, as well Redshift proxies. As one would expect the interactivity of IPR did slow down, but easily managed by using display layers to hide/show objects. Render time for 4k was about 90 minutes with dual Pascal TitanX cards, although I did crank settings higher than likely necessary since it was for a still. This is still super fast, especially since both 3D fog and DOF are on! I'll note that the DOF is what requires higher sampling, so if I were to do the DOF in post the render time would likely be cut in half... 45min for 4k? Pretty darn cool for a scene like this... I still haven't played with Redshift's AOVs, so this is a straight 32bit EXR render with just a little tweaking in Photoshop with the Camera Raw filter. I also set-up a bunch of Megascan materials that are ready to go for future projects, using several of their rock and leaf materials for this scene. Anyhow... has been a great experience so far switching over to Redshift and GPU rendering!
A couple weeks ago I decided to try out GPU rendering. After doing some research and talking to a few people, I was steered towards Redshift. Several studios have been using it and it seemed worth trying out. Was simply curious. A couple years back I switched from Mental Ray to V-Ray and the idea of converting my library of assets, again, was not super appealing. But, fun to try something new nonetheless. Anyhow, after a weekend with Redshift... holy $@#*! Running on a single 980 card it was insanely fast. IPR became useful for complex scenes including fog and DOF, seemingly about 10x faster than Vray. And easier... less fuss to manage sampling as the speed allows for the use of high rates and Brute force. And a bunch of other things but to sum up. It is cool and I've 100% switched. Just spent a couple weeks converting my library. Also upgraded my machine from a single 980 to dual TitanX cards. Yay for nVidia... and Redshift!
Here's a quick test I did after converting my library. IPR constantly refreshing as I imported random assets, set up a couple lighting styles with DOF and fog... all in about an hour. Really fun...
Decided to spend some time over the winter break going through older experiments that had potential, but were only rendered at 1280x720 to see what I could do with them. In the process I also decided to uprez some of the images in the 3D stills gallery to 4k. I recently got a new 30" monitor and some of the images in the gallery looked a little small! The images below are the result of some of the time spent adjusting textures and regrading / color correcting. Of the few I played with, I think I like these two the most...
And... I have a YouTube page. Added some misc animations as well as an entire tutorial on the making of Dirge: a lecture from the Gnomon Workshop. Still not much there for now, but hopefully I can record some more casual tutorials and things to put in there if time permits. Ultimately there are some things I'd be happy to share in regards to process that don't really need to be an 'official' Gnomon Workshop title. So we will see... but for now... it's a start!
New image... inspired by Titus Canyon in Death Valley. This summer I spent some time experimenting with Photogrammetry and created a bunch of assets such as tree trunks, logs, rocks and cliff faces. Fun to have an excuse to get in the car, find cool things and take a bunch of photos in order to build models with PhotoScan. This image incorporates a few, specifically the tree on the right, a couple small logs and rocks on the ground and the cliff wall on the left of the image... so about 35% of the screen real estate. The rest is made in Maya, ZBrush and a little bit of World Machine. Textures are a combo of 3D and some Photoshop overlays just to be quick about it.
