i am looking for some workflow that could help me with two sided cavity. My problem is that the model is too complicated for casting into two sided mold that uses just right and left part of the model. If I casted this model it couldn't be taken out of the mold because of the "dead angles" I tried to detect these dead angles by placing the model between two light, and expected that the area in shadows are in the dead angle and the lights will create a dividing line of the mold.
This is expected mold and where it will be divided into halfs
This is my light setup and the areas that needs to bee flatten or filled so the model wont stuck in the mold and it can be opened after the model is casted.
The workflow is not very professional, slow and kind of not exact as the filling and flattening is made by hand. Is there a way you could advise me to get better, faster or more accurate results to this. Or is it even something that shouldn't be dealt with within blender but using completely different kind of software?
I tried dense plane shrinkwrap from back and front with project shrinkwrap, and actually iam pretty impressed wioth the result. It showed expected dividing line and filled the black areas. Its too much sharp and edgy, but its something.
