painting one side of a surface

[mikalind]

Hi

Im looking for a way to get only one side of a shape painted.

Example:

There is a detail in a model that is a tube, lets say lens hood for a camera.
Is there a way to get only the inside of the hood in a material/color and another on the outside?
Or the inside of a flowerpot a lamp screen, a cupboard etc.
I suspect this can't be done in Keyshot but if i export the part as OBJ and open it in C4D perhaps.

Im fully aware of that this probably is no piece of cake but i would very much appreciate if someone could suggest a workflow that i could look into.

Regards

Mikael

In your native CAD, just apply UV Mapping, (any color) to each surface you wish to differentiate.

Hi

Thanks for your reply.

I know this is possible, but i get step files and there is no way for me to affect the pre work in CAD.
I was thinking more in a post CAD way here.

If it's not a solid, then I don't believe there is a way to do a 2-sided material in keyshot anyway.

What 3D software are you using? Splitting a part into pieces is a modeling change. I think the only way to do what you're asking is to use a decal as the second material.

Or you could just render it twice as 2 different materials and photoshop the results together.

Thanks

I think you are right. I simply have to get it done from the source rather then trying to do it afterwards.
I will lay my efforts there instead.
