Mobile model alpha fading

Questions & Answers
1

Hi all,

Basically I wish to ‘simply’ fade a model’s alpha.
I have read other threads and found transparent/bump diffused to work (in the editor).
My question is what’s the equivalent mobile shader for this? or am I meant to write my own ???

Any advice appreciated

Cheers

p.s. I haven’t tried it on a real device so don’t know if the actual alpha fade will work but assume it’s highly inefficient on this platform.

I don’t think there is a built-in mobile shader that supports diffuse, bump and alpha. You could modify one though to include alpha, multiplying a float value to the alpha. You can download the source code for all the built-in shaders as a starting point, or perhaps you can find one that someone has already created.

I’d suggest too that you test out the performance on a device. In my experience alpha fading objects works but can affect performance.
