thank you so much for hitting that +watch button! <3 I'm REALLY happy that you like what I draw! ^^
I hope you find the iRay tutorial as useful as I did. When my friend gave it to me I thought that many others might find it useful too so I asked his permission to share it. In the new DAZ studio you can set up those mods and save it in your presets folder which is what I did. Then I just add the preset to the scene and make some final lighting adjustments. What the tutorial doesn't mention is that you want to make sure the surfaces are adjusted for iRay; the easiest way to do that is with the iRay Uber-Shader base shader. Though I really like to use ParrotDolphin's lighter silk shader to adjust character skins. https://www.daz3d.com/pd-iray-shader-kit-1 - I use the 40% silk for the skin and the latex for the cornea/reflection.
I've added ParrotDolphin's IRay shader pack to my Wishlist. If I get any commissions of enough price, I will get those shaders. For now, I have to make due with free resources.
It's an excellent buy; it comes with a variety of textures you can use to spice up costumes as well as the basic shaders. She has another one as well that adds more textures.
