So I was able to get my painted tree Branch texture working in maya software but I needed to get it to work in Renderman as that is the rendering software we plan to use. Despite me saving my texture as a PNG with a transparent background, the background was showing up as white when rendering with “Renderman”.
It took a while but I managed to figure out the terminology for “Renderman” and how to control the transparency and visibility of my textures, now I can use flat textures to create leaves, tree branches and other foliage, allowing me to keep the poly count low
