emission light from both polygon side

[albehany]

hi first thing sorry if this post before i search for same thing but i don't find anything anyway is there anyway make emission light coming from both polygon side in octane c4d ???
please take look to photo to understand and one more thing i know if i Reverse Normals will show the light in the other side what i want the both polygon side
thank you in advance

hi,
you can do it only with octane 2.14 and a mix material with the new polygon side node in the ammount

hi bepeg4d i try your mathilde but for some reason doesn't work with me
take look to the attach image

hi,
sorry, it seems to work well except with the emission node, since the emission is made always in the normal direction and ii's always black in the opposite side
anyway i have solved duplicating the mesh, inverted the normals and moved by 0.1cm the surface with the normal move command, hope it could work also for you
ciao beppe

great to hear about the poly side node! I ran into this problem recently and also used the normal move workaround. An even faster/flexible way in c4d is to move the normals using a plain effector as a deformer... For my case I found the problem after I baked a simulation to PLA so needed to move the normals on every frame

It would not cast emission on back side of triangle. That's the problem.
