Flexible rain/snow texture in Torque

Download Code File

This little change allow to dynamically set the texture subdivision in the precipitation code. It allows more flexible texture with texture subdivided in 4, 8, ... parts.

So a classical precipitation texture file looks like that
It has 16 subdivisions and in each there is a raindrop.
However, it is impossible to have more detailed raindrop /snowflakes which was very important in DoP. The proposed code add one variable in the Precipitation datablock named numTextures which let you define the subdivision of your texture as shown in the following code :

datablock PrecipitationData(FunnyRain)
{
   type = 0;
   ...
   numTextures = 4;
};

You can then make much detailed texture like

You just need to download the provided file and replace your files with the one in the archive + recompile torque.
