Does anyone know if there is a way to use a image in COP network for Arnold dome light texture? I'm using this expression to read the image. op:`opfullpath("/img/comp1/OUT/")` It works with Mantra but it doesn't seem to work with Arnold. Perhaps this is not supported in Arnold? Thanks! -
I have a small compositing network which I want to reference as texture in the shader using the op: expression .ie op:/img/trail Even though I've managed to make it work several times, I always find it a bit flaky and many times mantra doesn't manage to load the image, even though it may be visible on the viewport when referencing the same image operator in a uvquickshade node, or just by loading the shader. It works with a principle shader out of the box, but if I put the same shader within a material builder it breaks. Is there a render attribute or something else I need to add to the shader? I understand it's better to use pre-rendered images the normal way, but I want to use dynamic heighfields SOPs for textures and ideally avoid having to write out thousands of frames in advanced.
