UV values and solid particles.
Read the documentation and the UV values are not what the documentation states.
The SPS uses only one material, so only one texture.However you can choose, per particle, which part of the texture you want to apply to this particle with the uvs particle property.This property is a Vector4 and is initially set to (0, 0, 1, 1) for each particle (or to initial UVs values if the model had UVs per face),
I have a single mesh, a single material and an array of 48 UV values.
First) The
have a look at this commented PG : http://www.babylonjs-playground.com/#2FPT1A#89
maybe not that optimized, but didactic (I hope) :
we use only one image file :
Each box has 6 different sizes : this is done by setting the texture per side on the box model (we don't apply any texture to it). We just say each side will receive 1/6th of the image width on its width and the whole image height on its height (like we had only one row in the image file)
Then at SPS initialization,
