Like you can use textures to make it look like you have void gradients etc..
Could you do like demolition left hand trail in a trail texture?

No reason you couldn't.

I mean where could you get the pics for them

Get a Toribash color pallet, find the color you want and then fill the trail texture with it.

I mean the actual trail, if I just fill the color in then it's just one color. On trails it is like abut transparent etc

He means when you have a normal trail it fades out in the edges thats what he means

No, you can't have regular trail fading with texture trails

Oh I see.

Yea, because if you make the trail a gradient, it will work for as long as it is showing the one texture. Then when it repeats it will go from nearly faded to nothing back to full color.
