meterial question
show user profile  aca88
Hi all,
i have a question about materiality. I am creating a surface that is deforming due to the interaction with a few objects. Typically a surface that is deforming with the Cloth modifier, and a few objects underneath it that cause the surface to acquire different tensions and curvatures.

Now i want to put a material on the surface in order to look like a streched plastic membrane. But the questions is how can i achieve the non uniform materiality looking of a streched membrane?
if i just put i.ea Plastic rubber material of 3ds max it will not have variations of materiality (transparent-opaque areas due to the streching)
For example if you look at a streched white rubber, there are certain areas (the streched ones) that are more transparent than the rest .
any suggestions ?

thanks

@Octopuzzy thanks a lot for this one. i ve been searhching this thing for some time in another project..

@K-tonne. sorry for the question if it is dumb but what do you mean sss ? well yes the idea is that the thickness of the material is actually affecting the transparency or not. like in reality. i can do that with scripting (which is what i will probably do eventually) but i was thinking if there is a faster and computetionally more economic way.

Really Great post Octopuzzy. Ive been looking for / planning to write a script that does exactly what stress does in your link.






$Entrepreneur = if((Designer + Engineer)*Programmer){Problem Solver};
