I'm new to Octane and C4D but loving the journey so far.....
Has anyone got any tips on getting accurate materials for thin films / PET ? I do a lot of printed electronics / membrane switch concepts and a lot of the time transparent PET / Mylar is used - usually only 100 microns in thickness.
I've started to experiment with basic acrylic / glass materials and get nothing showing through these transparent materials. If I scale the model x10 I do get better results and can see objects through them - but I'd like to stick with actual size models if possible?
Any help greatly appreciated...
Cheers!

Hi phil,
in which scale are you working?
Which kernel are you using?
Can you share some screenshots?

Thanks Beppe,
Default cm scale with OBJ models dropped in at actual size (so XY size ok but the total thickness of a layers is only approx 300 microns.
Can I share images privately (my client will not allow me to share publicly) ?
Tried DL and pathtracing.
I have tiny gaps (microns) between the layers (something I had to do in Keyshot to get transparent materials to play nice) - but trying to move completely to C4D and Octane ...

Hi phil,
I'm going to send you a PM, so you can replay and safely attach files.
Anyway, from what you are saying, I suspect that the the object is tiny, and you need to reduce the Ray epsilon value in the Kernel setting to correct the tollerance, in Path Tracing or PMC mode.
