VRay cannot modify the size of IES' lights

Just like in the picture, I increased the size of the light, but the effect did not change. I uploaded a demonstration video and project of the problem

Hello 123456_

If you are using IES lights, the scene should be up to scale. In that case, there shouldn't be a need to increase the size of the light, as the file comes from the manufacturer of the specific light with predefined intensity, direction, size, etc.

Тhere is a simple workaround if you want to increase it. Select the Light, go to the Attributes menu and only adjust the X and Y parameters. This should do it:



Could you, please, let me know why would you want to increase the IES lights?
