Bifröst Viscosity R&D in Maya and Renderman

Hi, this is my first post of 2017 and I will be aiming to post more often than before. As well as lighting, I am interested in exploring effects also. I have been experimenting with Bifröst in Maya and this is some R&D looking at viscosity settings to simulate a thick liquid. It turned out kind of like honey! It is not a very high res sim and some bubbling can be seen. I'm sure more time spent on the sim will address this. Rendered with Renderman in Maya 2017 with an average frame time of 30 seconds. Great fun doing this stuff.

Merry Christmas!


I've always had a big interest in painting and wanted to give the digital end of it a go. A while back I bought a subscription of Painting with Light and Color with Dice Tsutsumi and Robert Kondo. Two absolute geniuses. These are two paintings inspired by their class. The second one is a little older and somewhat disconnected from the whole Christmas thing but thought I'd upload it anyway. Studying and practicing paintings helps greatly with my lighting work and I plan to post more in the future. Merry Christmas!

Substance Painter to Maya and Renderman


Recently I bought a licence for the Substance Pack from Allegorithmic which includes Substance Painter, Substance Designer and Substance B2M. The more I was seeing what can be done with this software, the more I had to give it a go. This is my first shot at using Painter, it's not too fancy but I was more interested in grasping the concept and the layering system. It's not a 1:1 match in Maya, but close, I am happy enough with it. Really good fun to use and very powerful. Already it has me thinking about shading in many different ways and I hope to upload more soon. Model is from the Allegorithmic site.

Renderman Subsurface Scattering - Panther and Snake


Some more subsurface scattering shader experiments with Renderman. The sss is quite subtle here. The model is from Three D Scans.

Sub Surface Scattering Studies


Some studies involving subsurface scattering. One has some extra detail on the glass, just experimenting with how this affects refraction. I am planning to upload a more complete piece after my sub surface findings, it's such a cool and interesting subject.

Connemara Photo Trip


I haven't posted on here in along time. Connemara is a place I have wanted to visit for a while and eventually got around to doing so. Here's the best of the pictures I took while on a trip up there in mid July, I only got around to sorting these now. It was one of the nicest places I've been to, a dream for anyone who loves photographing landscapes. It's just so beautiful, wild and isolated. Such a contrast to Dublin! I definitely plan on visiting again in the near future. I was lucky with the weather I got, there was a nice mix of cloud and clear sky which allowed the sun to have a nice dappled effect over the landscape in some photos. This is especially visible on the Twelve Bens mountain range which dominate the Connemara landscape.
