VrayBlendMtl properties in the max curve editor don't show until keyframed?

[KenTankerous]

Maybe the title says it all? But I'll write it here:

In Max's curve editor I want to add some script controllers to the blend properties of the coat materials in a Vray Blend Material.

If I expand the material listing the blend properties aren't exposed. If I keyframe the blend (for instance from [0,0,0] to 255,255,255]) the property shows up and then I can add a controller.

Anybody know why this is? I'm trying to develop a maxscript for turning the coat materials on/off.

Thanks very much in advance.

We reproduced the issue and add it in the bug tracking system.

Thank you Zdravko, but I'm not sure it is a Vray bug.

I can say this much, for anybody that is wondering about the issue: If I type in the MaxScript Listener some code like

$.material.Blend[1].controller = point3_script ()

...it will work, the controller shows up in the curve editor. So: you can either keyframe it to get the property to show up, or you can directly add the controller through script.

I have no idea why this is, but if anybody is having this same problem there's another way to deal with it. If that helps anybody, I'm happy to do it. Thanks for your time.
