Back at it again with another preset question.

[RottenLemon]

Hello! Yes, I'm back here again with another preset problem.

So, let's just get right in to it. I'm making a transparent/scrolling preset, and I have the scrolling part down properly, but I was wondering how I'd go about separating the spots on the head? I want the mouth/lips to be transparent, but the tongue to have scrolling, and I'm not sure how I'd do that. I've seen it done before so I know it's possible at least. (Or, at least, I think I have.)

Possibly an easy thing, but any help is appreciated!

There is no real way to make the lips transparent without seeing the scroll through it. What I can suggest is applying the ghost code found here and using it only for the lips section to offer the illusion of transparency.

It's possible, let me get my code in order and I'll show you how.

Alright, so first we have a transparent head.

Then, we overlay a mask to let us know where we want the scrolling texture.

And finally, we have the scrolling texture.

The code to make this work is this:

Code: [Select]

material preset_12_headMatL
 {
    technique
    {
       pass
       {
 scene_blend alpha_blend
 alpha_rejection greater 128
 texture_unit
 {
 texture TRANSPARENT HEAD.png
 }
 }
 pass
 {
 scene_blend alpha_blend
 alpha_rejection greater 128
 texture_unit
 {
 texture HEAD MASK (BLACK AREAS WHERE YOU WANT SCROLLING).png
 }
 texture_unit
 {
 texture HEAD MASK (BLACK AREAS WHERE YOU WANT SCROLLING).png             
 colour_op alpha_blend
 }
 texture_unit
 {
 texture SCROLLING TEXTURE.jpg
 colour_op_ex blend_current_alpha src_texture src_current
 tex_address_mode wrap
 filtering trilinear
 scroll_anim 0.0 0.1
          }
       }
    }
 }
The result is this:

Just make the black mask over the tongue instead of the swirls that I did in the example, and obviously only erase the areas where you want transparency on the main head texture.

Thank you thank you! Seems to be working.

Locking this up as the issue appears to have been solved.~
