Most of the portals I have seen are either stone or metal, so I wanted to create a stylised wooden, rustic Portal with some wood paint dye that has faded edges. Something that you may find in a medieval fantasy or the witcher.
I used blender to create the model and substance painter to texture it.
Most of the model is texture painted, aside from the painting that I stencilled around the base and there are some wood fibres that are procedurally generated. I created a particle system in blender and use a vertex force to get them to rotate. Blender doesn’t have a built in way to export animated particles, so I found a script online that I ran in Blender to convert the particle system to an animated mesh.
