hi, I have a question about pyroshader in houdini16. There are fire shading and smoke shading parameters separately. That's why I was thinking we could control alpha of fire and smoke separately, too. However, when I change general > smoke > Density Scale value, it influences to fire alpha, too. Then if I set the density scale to zero, actually fire alpha also becomes zero although fire's RGB shows red-yellow color. Thus questions are: 1 - what's the reason/concept we don't have a separate "fire density(alpha) scale" parameter? (Of course, we can separate fire and smoke by AOV with smoke_mask and fire_mask.) 2 - Let's say I need to create a custom shader for it. What kinds of two volume fields should I use for fire and smoke's alphas? Also, inside of pyroshader, there is a pyroshadercore node, which is an essential node but cannot be unlocked.
