Ubersurface, iray uber base, layers and tiling.

AbnerK

I just realised that Ubersurface shaders are not iray!!!! I really thought that they were! No wonder I've had problems. Can some one just confirm that this is right! 

I think I know why I'm confused. iray uber base. ???? Could someone just pull me out of the rabbit hole I feel stuck in? 

What I'm trying to do is add a dirt layer to an iray fabric shader that needs tiling 10 times to look good. But obviously I don't want my dirt layer tiled which rules out using even LIE. What I've been doing is importing the maps into Photoshop and tiling them there, exporting and adding the dirt layer as LIE to save  getting too many Base layers. 

So does iray do multi layer shaders? I learend that if that 'Ambient' layer is called 'Diffuse' it's 3Delight  and if it's 'Base' then it's iray. My brain is now about to blow! :D

Oh, one last thing. Someone told me about tiling in iray using the Image editor but then that needs an extra layer, an extra slot for the dirt. I tried the Top Coat Color but it just wasn't strong enough an effect.  I don't want to use 3Delight at all. 

 

So, just to recap. I want to use iray.  I'm trying to save work, as we all do, but want my cloth material to look great. My shader needs tiling 10 times but I don't want my dust layer tiling. I'm hapy to use PS if I have to but I want to be most efficient. I have a tendancy to get bogged down in detail and forget the big picture, which is what I am doing now. I get the irony. :)

Thanks.

BTW, the image below is with the dirt in the Top Coat Color slot.

All very confusing, isn't it?

Uber Surface (and Uber Surface 2) are 3Delight-based shaders and so wil often not convert too well to use in Iary if the various options on offer in them are utlised).

The Iray Uber Base shader is, as the name suggetss, the basic Iray shader.

As for the tiling - I asked a while ago about tilign and Opcatity maps in 3Delight and was tols teher is one tiling factor per surafce.  But, as I understand it, you CAN have alternative tiling factors on different maps, but I will freely admit I am not sure how you'd do that, without dropping into the Shader Mixer

Oh, I don't feel ready for the Shader Mixer. I'd need a good video tutorial for that. TBH the Daz, official, tutorials don't really help me. I want to know I'm reading the right tutorial for what I need straight away. I tend to find I wade through a Daz tut only for find it's for something totally different. Then half the images were removed long ago. :)  

But as I said, I've no plans to every knowingly use 3Delight.  This sums it up really well

The Iray uber shader can do a second layer in the diffuse overlay channel.

Every image channel in Daz Studio, regardless of the shader can be tiled independantly of other maps in use.

Simply click on the little image icon for it on the surface tab, in the menu that comes up, go up to "Image Editor..."

A little window will pop up, go to the Instance Tiling Tab.

You will see Horizontal and vertical tiling options.

What a first rate hint! Works brilliantly, the girls and I thank you, they will be playing Netball soon now!!
