VRaySoftBox difficulties

[Morne]

I'm having a hard time getting the VRaySoftbox to work nicely in a VRay Plane Rectangle light.

I have a bunch of different lights, with multiplier varying between 5 and 50, but none of the softboxes seem to have an affect. (especially in reflections this is obvious)



As you can see, the reflection of the softbox makes a very harsh solid reflection. In the middle of this cropped pic, below the window and on the roof this is most obvious. If I decrease the multiplier of the lights, the scene becomes very dark and I have to compensate by increasing the exposure, in which case I end up with the same thing again. I've tried ticking radial, modified the frame gradient with a lot more points, but nothing seem to work.

Can somebody recommend a known "good" setting for softbox, or suggest an alternative? (that does not involve using different software).
Are there any known bugs with softbox?

This is with VRay 3.3

Can't you just decrease the reflection multiplier of the light? That should darken the softbox in the reflection, while illumination stays the same. As for the hard edges, when the surface is curved (like on the car door) the soft edge of the softbox gets compressed even more in the reflection, so simply making the soft edge in the texture wider could do the trick.

Where do I find the reflection multiplier? I only see ones for diffuse and specular

I tried making the softbox gradient wider, but as I said, no matter how many points I add in the gradient, it doesnt seem to have an effect

Oops, my bad, I meant the specular multiplier.

And why would you want to add more points to the gradient? You just need to move the one default point in the frame gradient to the left. But: You will get a better soft edge if you use the vignette gradients, instead of the frame gradient.

Jip, thanks the U and V works much better than the frame
Looks nicer now!
