Snowflakes are squares.

I'm toying around with the precipitation datablock and created my own for snowflakes. Things have gone smoothly except the snowflakes themselves are squares instead of circles.

The datablock code:

datablock PrecipitationData(LightSnow)
{
  soundProfile = "LightSnowSound";

  dropTexture = "art/environment/precipitation/snowflake2";
  splashTexture = "art/environment/precipitation/water_splash";
  dropSize = 0.35;
  splashSize = 0.1;
  useTrueBillboards = false;
  splashMS = 500;
};

snowflake2.dml simply contains:

Any suggestions?

Change the blendmode in particle editor.

Hm, perhaps I didn't do this correctly. I simply made a new datablock in environment.cs. It doesn't show up in the particle editor list, so I can't edit it.

I also had the same problem, I suggest to use your own shader for that:

you can specify which shader to use for the drops and splashes as you can see here https://github.com/GarageGames/Torque3D/blob/2044b2691e1a29fa65d1bdd163f0d834995433ce/Engine/source/T3D/fx/precipitation.cpp#L1633

To do that, add this to a .cs file (for instance, core/scripts/client/shaders.cs)

new ShaderData( fxPrecipitationShader )
{
   DXVertexShaderFile 	= "shaders/common/precipV.hlsl";
   DXPixelShaderFile 	= "shaders/common/precipP.hlsl";
 
   OGLVertexShaderFile  = "shaders/common/gl/precipV.glsl";
   OGLPixelShaderFile   = "shaders/common/gl/precipP.glsl";
 
   samplerNames[0] = "$diffuseMap";
   samplerNames[1] = "$alphaMap";
 
   pixVersion = 1.4;
};

then in your precipitation datablock add these two fields:

dropShader = fxPrecipitationShader;
splashShader = fxPrecipitationShader;

if you are still unhappy with the result, you can tweak the shader or make a new one, just replace the DXVertexShaderFile and the other ones with your tweaked/new shader.

NOTE:

Keep in mind that your texture is not in tiles as it is supposed to be by default...

Perfect, doc! Exactly what I was looking for.

Here's the snow sheet I ended up using, if anyone comes across this:

Looking good!
