Transparency from grayscale while in game
Is there a way to add transparency to an object while playing, from grayscale? I'm trying to use a heightmap generated from a perlin script to create a cloud effect, and i'd like to create transparency from the dark areas on the texture while in runtime.
texG.Apply();
That notoriously forgotten command... That's what I missed. Thank you for the help guys!
Check out the Particle Shaders like "Additive" etc.
have you tried this? Additive Shaders makes black pixel transparent and white fully visible
yea easy, just use a transparency shader and then in gimp or photoshop or whatever set an alpha layer.
to change the transparency of an object in general code wise.
void ChangeAlpha(GameObject Piece, float Alpha)
{
Color TempColor = Piece.renderer.material.color;
TempColor.a = Alpha;
Piece.renderer.material.SetColor("_Color", TempColor);
}
that will take a gameobject and a value from 0 to 1 (where 0 is invisible, 1 is fully visibly and .5 is partly see through) and set a gameobject WITH a transparency shader to render transparent.
@sprkzbarca Not really what the I was asking. What I need to do is change the alpha of a texture pixel by pixel while in game. This is what I had, and it wasn't working, but it should give a better idea as to what i'm trying to accomplish:
if(modify3){
for(int x = 0; x < texG.width; x ++){
for(int y = 0; y < texG.height; y ++){
UnityEngine.Color col = new UnityEngine.Color(texG.GetPixel(x, y).r, texG.GetPixel(x, y).g, texG.GetPixel(x, y).b, texG.GetPixel(x, y).grayscale*255);
texG.SetPixel(x, y, col);
}
}
}
