Wall with transmission set to 1.0, and specular to 1. Wall with transmission set to 1.0, and specular to 1.0 : Wall with transmission set to 1.0, and specular to 0 : All objects except the wall, have a toon shader with specular set to 0.1. I made a simple scene to test this out : a directional light, a large plane, a simple wall, two teapots (one on each side of the wall), and some basic geometries to test reflections. (I made sure to uncheck opaque for my glass object ). Instead its showing the HDRI image from skydome light. As the glass object is transparent I want the refraction to show the image from image plane. There's a skydome light with HDRI image & a image plane behind the glass object. Is this behavior normal or is it a bug ? Because nothing in the documentation specify that i need to have the specular weight to 1.0 to have the transmission working. Need help with arnold lighting in Maya I have a glass object in scene. We act as a credit broker sourcing credit to assist with your purchase from a carefully selected panel of lenders. And if i have a lot of objects, it would be tedious anyway. Arnold Clark Automobiles Limited is authorised and regulated by the Financial Conduct Authority for general insurance and consumer credit purposes. I can cheat a bit and disable the specular visibility of the objects visible in reflections, but then i loose the ability to have the reflection of this objects on an other surface. But then i got reflection on this surface, that i dont want. The problem is, with transmission weight set to 1, it doesnt work, unless i set the specular weight to 1. I would like to make a toon glass shader, using the new arnold toon shader.
