Week 10: River Simulation Fix, Lighting, Camera Movement, & Render in Maya

In this week, I decided to fix the river simulation (as I was having issues with the water speed and density of the flow), to then illuminate the scene, and prepare the camera movement following my initial story board.

River simulation fix

Since my previous river simulation was way too heavy and it was giving me problems to see the actual speed of the water (I needed to render the whole simulation if I wanted to see the effect as the playblast was not showing the effect), I decided to find another way to simulate water that was not that heavy on the scene. So I found in YouTube this tutorial that uses a noise shader instead, and then I could just use the glass texture and coloured it to make it look ‘wet’.

I then also considered in polishing my river water simulation effect, as the waves were looking a bit too big for a river. They seemed to be more for a lake or a pool, but a river has smaller waves as it is more like a flow of water that follows a unique direction. Then, in the noise shader, I reduced the scale of the waves and added a bit more noise.

Lighting, camera movement, and render

For lighting conditions, I searched in Polyhaven for HDRIs that simulate the light we experience at sunset. It should be subtle, yellowish, and that projects soft and stretched shadows. I found an HDRI that was not giving me the exact light conditions I wanted so I also tweaked the amount of light the it was producing and make it slightly darker.

Once the lighting was done, I started to do the camera movement is my scene. I did not want to show only that outer side of the environment from afar, so I made camera to pass through the rainforest to show the trees, palm trees, and foliage, to then jump over the river, going around the scenario in circles, to finish climbing up the pyramid up un til ending in a long shot of the environment.

Camera set up

In the following render of the scene, it is visible the camera movement I set in the scene, however, I noticed that I had some texture problems with the trees leaves, so I will need to revisit the textures paths, relink them properly to avoid this issue, and render again the scene.

Week 4: Trees Modelling in Maya, & Previs

In this week, I started to research tutorials to model trees trunks, branches, and leaves in the most effective way, to then begin to model the trees of my environment. I also put together a previs to see the dimensions of the space.

As I am not that familiar with organic modelling, I researched some tutorials to see what was the most efficient way to model a tree. I found the following tutorials that explain step by step how to model a tree’s trunk and branches separately, how to create different variations from the same original model, and how to put everything together once we have our parts modelled. I think this way I will have different variations of trees to fill up my environment and not having to model them one by one from start.

For the leaves, I found a separate tutorial that shows how to model them in groups to then pile them up in different shapes, and ultimately, add them to the tree branches.

Following these tutorials I started with the trees modelling.

Before making the branches and leaves, I wanted to see how much space I had in the environment and how the trees would fit ini it (dimensions). So I expended some time positioning the trees in the space until I reached a preview of how the environment would look like with the pyramid included.

I also made some renders of the frames to see how the camera movement would look like.
