Is there a way to make certain parts of a texture look like its glowing?
I am assuming that you have setup your uv map, and you know how to texture paint?
If so, you can paint a separate image, just grayscale.
Then you can add a Mix RGB Node, put the separate image into Color 1, the Mesh Color Texture into Color 2, set the fac to 1, and the mix type to Multiply.
Put the output of this node into to the Emission Color of the Principale BSDF.
Also if you are using Eevee, turn on Bloom.
I haven’t tested this now, there maybe a huge mistake but anyway.
I can explain it on Monday in depth.
Yes, I have my UV map and I have basic knowledge in texture paint. It all worked out fine, but now I’m curious, how does this work?
The Mix node set to Multiply works the same as in Maths. So think of your grayscale image as a multipler, if the color is Black(0,0,0) and the texture color is White(1,1,1), the formula with be 0*1=0, which is black.
A object can’t actually emit black light [citation needed] so by changing the emission color, light can be emitted.
Bloom mimics the effect of light scattering in the air.
