Midnight recording on how to do a basic texture bombing shader:

Amazing technique!

How would you go about doing this in Redshift?

Thanks!

Thank you @velk.

If texture bombing doesn't exist in Redshift, you could bake a texture before rendering. I have posted a file about creating textures from SOPs recently:

I try to add new feature to your texture bombing tool, I will like to have layer ability later like the old FX TD bommbing shader which is not compatible anymore and for now adaptive variable scaling work and alpha kind of works but not really like i want.

Do you know how i could reveal the underlying color?

 

i also try some stupid code like this but obviously

vector4 RGBAtex = colormap(image, tex);
f@Alpha = RGBAtex[3];
v@Cd = colormap(image, tex);
v@Cd += (1-@Alpha)*@color2;

 

thanks

Also tried

 

vector color_sum = 0.0;
float alpha_sum = 0.0;
float alpha = RGBAtex[3];
vector color = colormap(image, tex);
float mask = alpha * (1.0 - alpha_sum);
color_sum += color * mask; alpha_sum += mask;

v@Cd = color_sum;
f@Alpha = alpha_sum;
