Seeing if snow is already lowered.

Hey all, I want to add a speedbuff to my player in the snow when the character is not pushing snow down. I have a working shader for lowering the vertexes using an render texture. What would you advice doing to check if the player is pushing snow down? Current the texture is create by placing red particles on a separate layer.

How the texture looks:

Thanks in advance!

i guess can do getpixels/readpixels from rendertexture,
to check from player position and/or forward a bit, if there is already cleared area.

or separate 2d array that you fill with cleared/not cleared values, and use that as a speed multiplier…
but i guess thats the same as checking pixel color directly.

I actually tried the getpixel solution, but it wouldn’t work so I was hoping for something using the particle system!

readpixels should allow taking 1pixel or bigger area (note that the 0,0 point can be lower left, or upper left)

So i tried that already but just got a Color with rgba values all .82f. That’s why I asked. Will give it another shot later
