Eroding statue heart
Hello, here's a submission for a challenge hosted on a Houdini server. The challenge is titled "Erosion Effects Timelapse." For my entry, I chose to create an erosion effect on a heart-shaped statue, inspiration primarily from the styles of Daniel Arsham and iammaskarade on Instagram. It's a fun project for me because it's a little bit more abstract that what i do in general.
Crystal Infection
I optimized the mesh from @brainstation on Sketchfab in order to create the textures.
To achieve this effect, I decided to use VDBs.
To control the effect, I use multiple noises. The first one is for shaping the main parts that are going to erode first, and the second and third noises add some details on the edges of the first noise.
To create the erosion effect, I used a solver so that on each frame, it takes the previous frame and adds the effect.
Then, for the crystal infection, I decided to first make a path with a paint attribute so that it would pass where there had been erosion.
For the crystals infection, I chose to use this method because it was quick and easy to set up with a cloud point and a loop.
Then the solver gave me red dots with a gradient, which gave a little organic effect at the end.
To model the crystals, I applied some displacement to the geometries.
I then converted the geos to VDB and then to polygons so that the result would be smoother and the crystals would be merged together.
