The wings of an insect produces a rainbow of colors at certain viewing angle. How do we replicate this kind of effect in a game character? I know how to bring that effect within blender but if I want to export the model games, is this effect possible with some texture maps?

I have attached a gif image of a game character for reference. I am concerned with its wings that changes its color according to the camera view angle. Its gives a rainbow kind of color or like an oil reflecting... (I don't know the correct term). How do I bring this kind of an output for a game character?

Are these shaders in-built in game engines? or are there any texture map that brings these effect? Please tell me about this.

  • $\begingroup$ Hi. Please use a title that matches the content of the question. It should be descriptive but succinct, unique and identifying, summarizing the issue so that anyone searching for a similar problem is likely to find it. Remove anything superfluous, avoid using words like "this", "help with", "issue" or "question about", instead describe what "it" is. Remember, your title is the first thing potential visitors see, answers you get depend heavily on how insightful it is. See What is the problem of asking “How do I do this?" $\endgroup$ Jan 24 at 9:42
  • $\begingroup$ Not sure if this is relevant to Blender SE. The shaders have to built in-engine. But, those shaders may use textures (for example, to specify the colors at certain angles-- maybe, here, a sphere map aka matcap.) It's not shaders or textures; most of the time, it's shaders and textures. $\endgroup$
