Just out of curiosity

Hi,
Just out of curiosity, why do we have "Half-length / Half-width" in Size for a Vraylight Plane type ?
I don't know why but it's the first time I ask myself "why half" ?!

Hi,

Vlado has explained it in the following thread :

Thanks for your quick reply !
Sorry, I didn't search any post about that because I was convinced that my question was stupid and I was the only one to ask myself why... ! :P
Anyway, I thought about sphere light (with the radius parameter) and this trick of half size...
I understand that it's a minor thing and it could be something tricky to change (indeed, compatibility with older scenes) but I always "struggle" against it... I must include that trick, that's all

Generally, adding more options or check-boxes to the V-Ray light is something that we want to avoid, but it could be made more convenient for users that prefer to set the full size directly.

Here are some tricks that you can use for your workflow:
1) Type the full lenght/width size with "slash" 2

2) use the "wire" parameters expression to adjust the light size using a simple primitive.

Hey ! thanks for advice !
I'm not for adding option or check-boxes ! I like the way it is. And as I said, it's a minor thing.
It's just me, I have to remember half size and then, there is no problem.
Anyway, Thanks for the trick, I certainly have never thought about the wire parameters expression !
