Ok, the problem is in the script, try this one instead:
material preset_4_bodyMatL
{
technique
{
pass
{
lighting off
scene_blend colour_blend
depth_write off
cull_hardware none
cull_software none
texture_unit
{
texture InvisibleTex.png
tex_address_mode wrap
filtering trilinear
}
texture_unit
{
texture TransparentMarkingTex.png
scroll_anim 0.01 0.02
tex_address_mode wrap
rotate_anim -0.01
wave_xform scale_x sine 3 0.1 0 3
wave_xform scale_y sine 3 0.1 0 3
colour_op alpha_blend
}
}
}
}
i just removed this texture unit:
texture_unit
{
texture InvisibleTex.png
colour_op_ex blend_current_alpha src_texture src_current
}
and now looks like this (it is moving and it does not looks very good at the screenshot):
