Is the lumen setting not working properly with V-Ray Next?

Is the lumen setting not working properly with V-Ray Next?

- Common fluorescent light = 1200lm 3x85cm Object Light or VRayRectLight
- EV10

Very dark. The same conditions are bright in V-Ray3dsMax.

I have attached a test scene.

Hello,

Thank you for the question. The V-Ray Lights work the same way in SketchUp and in 3dsMax. The difference which you see is because of the different gamma corrections used for the V-Ray material. To achieve the same result in 3dsMax as in SketchUp, use a VRayColor texture slotted in the Diffuse of the wall material with the same R/G/B values and color gamma set to 2,2.
The difference comes from the actual material color in 3dsMax and gamma correction is applied to the color box and material preview by default while in V-Ray for Sketchup the material and its color are not modified. Let me know if you have further questions.

Kind regards,
Natali
