I am creating a material using a CustomShaderNodeGroup. The inner node tree has a texture, so I want to expose the texture parameters to the node UI. For doing so, I look for the texture inside the node tree and directly expose the different properties. But there is still one missing part I;m not sure how to do it. At the moment I have the following UI for my custom node:
As you can see, i have a similar UI as the original
ImageTexture node, but I'm missing the open/new buttons and also the use fake user and all that stuff for the image itself as in the following image
With my current UI, the user can't open a new image, so this is a strong drawback. How could I make something more similar to the original ImageTexture UI?
