Questions & Answers

Q: What are the different techniques for painting in video games?

There are three popular techniques: painting on vertices of meshes, painting using light map coordinates, and painting on a texture in UV space.

Q: Why did the tutorial choose to paint in the UV space to recreate the Splatooning effect?

Painting in the UV space allows for precise control over the placement of ink and ensures consistency with the game world. It also enables the use of a fragment shader to create the desired visual effect.

Q: How does converting the workspace position to UV space help in recreating the effect?

Converting the workspace position to UV space enables the rasterizer to recreate the UV islands, ensuring accurate placement of the ink on the meshes.

Q: How does the tutorial handle UV remapping for the meshes?

The tutorial remaps the UV coordinates to fit the range of -1 to 1, as expected by the rasterizer. This ensures proper rendering of the painted textures.
