add thickness on render time

Support Lighting and Rendering

Hi, i created snow fall. The snowflake is a flat 2d plane/grid with snowflake texture on it. The problem is because it’s a flat grid/card/plane (means has zero thickness) , when the snow is rotating or twirling around and at the time when that plane is parallel to the camera view (so you see a flat line) then it won’t visible in the render ? it creates an effect as if the snow is on and off during the falling.

  1. How can i fix this the simple way without too much adding too many additional faces/geometry ?

  2. How can i fake this in render time so the zero thickness plane (when parallel) will have a thickness so it will be visible in render output.

  3. or any other tricks ?

Thanks

if you’re rendering with Cycles, pure geometry actually renders faster than alpha planes, so I’d suggest modeling your snowflake

You could use the solidify modifier and disable “Display modifier in viewport” (eye icon) after adjusting the desired thickness.
