hi all,

can someone plz help me how to make a divide merge of two footages ?
im using this technique to composite rendered footages ---> http://www.spot3d.com/vray/help/VRayHelp150beta/tutorials_anim.htm#3dsmax
but im not able to do a division of 2 images. even though it should be possible with Digital fusion i cant find suchblending mode or operator.
ive managed to do it with vrays vraytex map under 3dsmax

any help appreciated, thanks.

screen is not the same as divide, i have tried that, in fact all blending modes and none gives the result it is supposed to when i check and compare with the vraytex map result
here are the results ---->

this is what it is supposed to look like (vraytex map divide)
