Iray Uber Base application issue

crashworship

I'm having difficulty applying the Iray Uber Base to primitives that I want to convert to emissive surface lights. The process goes like this: I load the character(s), props and environment, set up poses and placement of these items, and then begin setting up lighting for Iray renders. I create a primitive plane at the default settings, rename it "plane 1", select it in the scene plane, double click on the Iray Uber Base which then becomes available under the default tab in the surfaces tab. All well and good. I create a second primitive plane which is automatically named "plane 2", select it in the scene tab, double click the Iray Urber Base just like I did for the first plane I created but the Iray Uber Base items are not visible under the default surfaces tab. Those options remain the same as when I created the plane and no Iray uber base options are shown. If I save and quit the scene, restart Studio, redo the Iray Uber Base application, sometimes it will be applied to that plane, sometimes not. I may have to repeat the save, quit, restart and reapply two or three times before I can apply the Iray Uber Base to the second or third plane primitives that I want to convert to emissive Iray lights. Applying Iray Uber Base always works for the first plane primitive but never for additional plane primitives unless I save, quit, restart and then reapply Iray Uber Base.

Some technical details: DAZ Studio 4.8.0.59 64 bit Pro Edition; 27" iMac late 2013 3.5 GHz i7, 16 gigs DDR3 memory, NVIDIA GeForce GTX 780M with 4096 MB memory, OS X El Capitan 10.11.2

Any thoughts on why this is happening? Is it a glitch or is it intentional that Iray Uber Base be applicable to only one primitive per scene? Has anyone else experienced this issue?

Did you make sure that you have both the plane selected in the Scene pane and the plane's surface selected in the Surfaces pane?

Ah, I see your point. Select the plane primitive in the scene pane and then select that item in the surfaces pane. I've been going at it like I do with loading materials/poses to props and figures, either by selecting the target in the scene pane and then double clicking the material or dragging it to the item I want to apply to. It never occured to me that both had to be selected in each pane. It seemed intuitive to me that applying materials/poses/etc to figures et al by dragging or dropping or by double clicking so why not apply presets the same way to surfaces? I will try that and see if that works. Thnx.

Material presets have the names of the surfaces built-in, so just selecting the item is sufficient, but shader presets can be applied to any surface, so you need to make sure the surface is selected as well.

Thanks. It seems to be working now. Transitioning from Poser to Studio has presented a bit of a learning curve. Being presented with problems and solutions like this helps move that curve along a bit faster. Now it's how to get all of the content I have which is designed for work in Poser to work in Studio. Exporting from Poser as an obj works, to a point, but limits functionality. Wouldn't it be great if both applications spoke the same language? I won't hold my breath on that one.

What Poser content is causing trouble for you?  Most should work fine in DS loaded from the Poser files, except for dynamic clothes and hair, P9+ weight mapping, and procedural materials.
