Hi!
I’m very new in Unreal Engine development and I’m trying to create a star with a material.
This is my material:
And this how I can see it in my game:
But they don’t have brightness like these:
What I can do to make them look like?
Try increasing your ‘color de emisión’, but to make them look like in the image you’ll probably need to use a custom graphics, not just a color.
Thanks. What do you mean with ‘custom graphics’?
Hes saying that you will most likely need to use a texture that looks like the star rather than just a plain colour parameter.
Yeah, that’s exactly what I meant.
Ok, so I need to add a texture to my parameter ‘EmiterColor’, isn’t?
This texture, does it must have the shape of a star? Like this one:
I’m going to watch Materials video tutorial this afternoon to learn more about it.
I have followed this tutorial, 1.5 - Emissive | Unreal Engine Documentation, and it seems that it is what you have suggested me.
I’m using a sphere. Is there anyway to always show the face with the texture to the user? Or maybe, does exist 3D Textures?
Following the recommendations, I’m using a texture with the emissive color. This is the material graph (I think):
And this it how I see it in the game:
If I change Glow value in material from 10,000 to 10, I see it in game:
This second one, looks like a star, but it doesn’t have a star’s brightness.
To render it I use a Blueprint billboard:
Does that texture have an alpha channel, because it doesnt look like it.
I don’t think so. Here is the texture:
You need to look into create alpha channels for transparent textures.
