I only modified the values of the last two on the first row, the lava/magma ones that in your screenshots not shows.
The unique diference between this ones and the flames, water or others is that they have negative values on PositionY and FadeY.
If now you can see the lava/magma shader then seems i found the problem and will be easy fix them, so please, tell me now are working! XD
