Material Editor '1,52' entry

[Mcubed]

I've seen this in other fields too but can't replicate it. See Attachment.

don't understand what your asking? replicate the value in the index of refraction? just type it in the box.......explain further

[Mcubed]

When I type '1,52' in the field it changes to 1.0

[JamesTaylor]

that probably because your writing 1,52 - 1, (comma) 52

when it should be - 1.52 - 1.(point) 52

[Mcubed]

you know i guess your right. it just looks like a damn comma on thier screen but not mine. thanks.

[JamesTaylor]

no problem

It probably IS a comma. While in the US people us a period for a decimal point, in most other countries in the world, they use a comma. So it is probably a screen capture from a computer from another country. The IOR is a coefficient of the difference between two different materials, in this case, most likely glass and air. This value becomes important when it comes to calculating refraction and when it comes to calculating at what angle rays stop refracting and start reflecting specular light, aka the fresnel.
