Its Autumn and the trees are turning.
A few renders in the Terrace building overlooking Hallandsas. I am currently looking at the difference between the artlantis render engine and the maxwell 3 engine.
The scenes are slightly different in terms of geometry etc but its a good way to test advantages and disadvantages of the different software.
I used the same hdri for both and post processed the autumn sky into the scene which is a compromise but one i can live with.
Artlantis : 1hour render time (5000×2800)
Having used Artlantis for many years i have watched it slowly become a pretty ok rendering engine. Its fast which is great for most things. Its a biased rendering engine which at the end of the day means its trying to take some short cuts to get an output which is good enough.
The render time is pretty amazing (i have a late 2013 quad core imac with 32 gb ram) but i always have to do lots of post-process work in photoshop. There isn’t depth to the darks or the lights which results in under exposing or over exposing elements. Im guessing this is partly down to the biased rendering engine.
Shadows don’t come from the hdri so an artificial sun is used for this. For this shot i placed the sun from behind the room as to not cast sun shadows.
Maxwell : 10hours render time (3600×2016)
Im slowly understanding the purpose of maxwell for my work. Its a physically accurate rendering engine which doesn’t short cut the path of light falling on the scene. It does take ages to render something useful, especially interior scenes. It doesn’t produce a crisp image until it gets past a certain sampling level, unique to the scene. I find that when it starts getting over 15 hours its time to stop for me. Under 15 hours i haven’t had a none-noisy scene but its good enough.
The cool thing about maxwell is that if you import lights you can tweak them as the render is processing. Basically you can get both day and night renders from the same render.
I also think Maxwell comes into its own during night renders.
