translucent or transparent

Unity Engine
1

i want a translucent image
no what i want is a color like red and then make it
translucent so you can still see red but not good and then use it as
a texture. i have searched for it for days but cant find something good
only transparent but i dont want that…
could someone help me ?

p.s. i dont got photoshop but i have paint.net

you can use whatever you want as long as you export png with alpha data in.
the important thing is to use the right shader in unity (one of the translucent ones instead of the normal ones) and it will just work :slight_smile:

create an alpha channel for your image.

most RGB images are composed of color channels. you generally have three black and white channel to show how much red there is in an image, how much green, and how much blue. the number of degrees of white or dark in each of these channels denotes the “bit size” of an image. most true-color images are 24 bit, or 8 bits per channel. (i really couldn’t tell you exactly how the whole bit thing works.)

by adding an alpha channel, you now have a 32 bit image. you can use this extra channel for all sorts of things, but traditionally it’s used for transparency. the transparency shaders in unity will reference the alpha channel of an image to render partial or complete transparency.

so in simple language:

  1. create an alpha channel for your texture in photoshop
  2. fill that channel with a flat greyscale value, white being fully opaque, black being fully transparent.
  3. in unity’s texture import settings for that texture, make sure it’s importing it at at LEAST dxt3 – so it’s not throwing away the alpha channel.
  4. you should be able to plug that texture into a shader that allows for transparency and get a half-transparent material!

have fun.
