How to Transparency and framework ?

[Wchris]

i have a problem with tranparency

 

There is a tutorial about transparency, but it's not using framework.

 

i used ADN to create a red transparent texture for the bouda, but when using it in my project the transparent object is overriden by water and terrain.

 

***********************************************************************
                 Material Generated by ADN 1.1 R3

***********************************************************************
texture0="abstract::red.dds"
clamp0=0,0,0
color=1.00000000,0.141176477,0.141176477,0.589999974
blend=1
depthmask=0
depthtest=0
alphatest=0
overlay=0
zsort=0
cullface=1
castshadows=0
specular=0.759999990
bumpscale=3.06999993
gloss=0.460000008
shader="abstract::mesh_diffuse.vert","abstract::mesh_diffuse_specular.frag"
shadowshader="Abstract::mesh_shadow.vert",""

 

I don't understand what's going on. here's a screenshot. Any clue ?

 

tryed to use the transparency world to load the mesh and material, but same result

 

Thank you, this is driving me nuts

 

 

i hope in LE3 it will be easyer to use transparency without playing with worlds, just telling the transparency ratio et voilà, but LE3 is far away

Still searching...

 

got something working with

***********************************************************************
                 Material Generated by ADN 1.1 R3

***********************************************************************
texture0="abstract::red.dds"
clamp0=0,0,0
color=1.00000000,0.141176477,0.141176477,0.589999974
blend=1
depthmask=1
depthtest=1
alphatest=1
overlay=0
zsort=1
cullface=1
castshadows=0
specular=0.759999990
bumpscale=3.06999993
gloss=0.460000008
shader="abstract::mesh_diffuse.vert","abstract::mesh_diffuse_bumpmap.frag"
shadowshader="Abstract::mesh_shadow.vert",""

 

Now it's transparent but visually it's not like the first screenshot

 

i did not want it to be affected by light or shadow, i just wanted a transparent object that acts like a ghost 3D placeholder and tells the players where to drop his item with the same shape.

thank you, i have probably missed something, i'll try again

I would experiment with z-sort and overlay. They both have affect on which layer is rendered first etc.

Ok got it working ,

loading my mesh into the framework transparency world was not enought

The trick was to render the transparency world myself after RenderFramework like this :

        RenderFramework;
        SetWorld(GetLayerWorld(GetFrameworkLayer(2)));
        RenderWorld;
        LEsetWorld(GetLayerWorld(GetFrameworkLayer(0)));

Why is framework not doing this itself in RenderFramework ? I have no clue but there is probably a reason.

 

this is the final material file
