SY Gradient Shaders and Merchant Resource Iray

Has anyone given this a try? So far for me, all cloth renders black - including gradients that don't use black. Some metals show one color or the other but not both. I've tried all kinds of scaling options with minimal success, aside from flipping one color to the other on metals.

I recently had major work done on my computer so I'm on high alert for problems that could be related to that, but it has now been a couple of weeks and I haven't been seeing issues.

I've had a quick look using some base primatives as test objects. Applying any of the three "Cloth Base" items does turn everything black but using any of the colour ones sets them to one colour (not always black). I was able to flip between the two colours at either end by using the scale modifier. I believe that you also need to use the blend multipliers to set the right values so that you get the actual gradient to show. However, it seems I have not yet had enough coffee to figure out the right application of these yet.

EDIT: Here are some examples:

These were made using a 3m plane primative in the middle and the "ghosts" are 2m plane primatives. All had a cloth base applied and then a colour preset which made them all one solid colour at the default scale of 8%. For these I had to drop the scale down till it was between values where it would flip from one colour to the other - the central one down to -5.6% and the others are set to -16%, -8% and -6%.

Still not quite got my head round the blend multipliers, the first one does move the point between Colour1 and Colour2 but the second one does not seem to have an effect. Although perhaps that is because I used a negative scale.
