Dexsoft trees leaf issue

[Rick]

The leafs from some of the Dexsoft trees seem to have a black background instead of transparent. Is there something I need to do in the shader to make the background transparent for the leaf part of the texture? I notice the trunk and leaf are part of 1 texture file that the model uses, and the dds file is transparent.

 

This is what my mat file looks like, maybe I'm doing something wrong here:

 

texture0="abstract::oak1_c.dds"
texture1="abstract::oak1_n.dds"

shader="abstract::mesh_diffuse_bumpmap.vert","abstract::mesh_diffuse_bumpmap_specular.frag"

I suspect you probably want to use the following Rick:

 

texture0="abstract::oak1_c.dds"
texture1="abstract::oak1_n.dds"

shader="abstract::mesh_diffuse_bumpmap.vert","mesh_diffuse_bumpmap_specular_alphatest.frag"

 

I'm assuming you have the specular map embedded in the alpha channel of the normal map. If not then you need to do so or if not using specular then use the appropriate version of the frag file.

 

It's the alphatest your missing which acts on the diffuse texture giving you the transparency.

[Rick]

hmm, if I do that the model viewer crashes.

 

log says

Error: Shader file "mesh_diffuse_bumpmap_specular_alphatest.frag" not found.

 

Wouldn't that be part of the shaders with the engine?

[Pixel Perfect]

Yes, it's a standard frag file supplied in shaders.pak Have you got a path problem ?

[Rick]

Ahh, no abstract:: in from of the frag!

 

That worked. Thanks Pixel!

[Pixel Perfect]

Opps ... my bad! Missed that when I pasted it in to your mat file contents. Anyway, glad its working.

blend=alpha

shader="abstract::mesh_diffuse_bumpmap.vert","abstract::mesh_diffuse_bumpmap_specular.frag"

 

that should also do it if you got the alpha channel used in the leaf texture..

alphatest sometimes got rough edges as it just skips the pixel with an alpha lower a specific value (dont know how much this was atm)

Opacity mapping without skipping half of the alpha-channel values works without _alphablend shaders?

This is part of one of the .mat files I use with thier palm trees pack.

 

specular=0.25
cullface=0

shader="abstract::mesh_diffuse_bumpmap_sway.vert", "abstract::mesh_diffuse_bumpmap_specular_alphatest.frag"
shadowshader="abstract::mesh_shadow_sway.vert","abstract::mesh_shadow.frag"
