I have been successfully using custom shaders (fragmentShaders) for color and alpha, but the objects do not respond to light. They look the same even with no lights. How can I make the objects render in a standard way? I have been invoking the shaders as indicated in the a-frame docs: material=“shader: my-custom”.
Can you share a photo of what you are seeing? More information would be helpful.
Have you tried adding a shadow component to them?
The image “petal” is of a sphere with a point light that should reflect in it. The light does reflect if I do not use the custom shader. “petal” is the same if I comment out all the lights.
The other attachments indicate that I am using input from the scene (many lily pads and blossoms) to drive the shape and colour of pads and blossoms.
Two of the attachments indicate that I am learning from Grid Glitch and also from The Book of Shaders.
Adding a “shadow component” is news to me. Can you expand on that?
Thanks for your advice.
You could implement a Lambertian Diffuse in your custom shader provided you have the transformation data of the light(s).
