Question by DaJuice · Dec 21, 2012 at 06:51 PM · shadow

Best way to have shadows in iOS?

I need to find a way to get those shadows working with minimal impact on performance, because this game is focused on mobile platforms.

I thought I found a solution, first I'd use a second camera and make everything the camera see (alpha!=0) black and semi-transparent, but I don't know how to use Camera.RenderWithShader (nothing seems to make a difference) and I'm not even sure I could do this with that.

Then I thought about renderTexture, seems to be more optimized, but still I'd need to render the whole scene twice to make it work or I could render it once and use the texture twice with one normal and one shadow, but the result for the "normal" texture would be really ugly and it would take much RAM... Well those are my two solutions, any other idea on how I could achieve this?

By the way, the effect I'm trying to get is one like in this game alt text
