Adding Emissions to Custom Textures

Guide To Beautiful Games In Unity

Objective: Create a emission texture to make texture glow

First of all drag the texture map to the photo editing software. Here, I am using Photoshop.

Then go to Select > Load Selection to select the transparent texture.

Then Type shortcut Shift + Ctrl + I or go to select > Inverse to select the layer that we need to create an emission of.

Now create a new layer and give it a light colour.

Similarly create a new layer again and give the inverse of first layer the full black colour.

Now save the image as png to use in the material.

Then check active the emission and then drag the emission texture to the emission. Then change the HDR colour to preferred colour to define the emission colour.

And this is the final result.
