The following playgrounds are an attempt to produce a lot of labels with different text on with a fast fps. To do this I used the solid particle system for #1 and #2 using a dynamicTexture and for #3 an external image. In both #1 and #2 I created a dynamic texture and used a loop to fill it with numbers, each number being in a cell of the same size. I then created a plane in proportion to the cell size, built an SPS where each particle is a copy of this plane. By adjusting the particle uvs
