This was taken from another thread directly from Bungie Help. [quote]Hello all. This shader should become available after collecting all 50/50 Calcified fragments. If you have done this and still do not have access to the shader within your Collection, please let me know in the form of a reply to this thread. Please provide a screenshot showing that you have 50/50 Fragments (This can be seen in the Director when viewing the Dreadnaught), as well as a screenshot of your collection showing the Beltane Shader unavailable. Thank you for your patience.[/quote]
