soft particle question - 11/05/18 12:24
Hi!
I've got that soft particle shader from the wiki, but it turned out that it won't work without sky, or with a sky that uses custom shader. I guess it's all related to it's 'depth' thing, but not sure. Can anyone help me out here, or point me in a right direction? Help you in advance.
Some screens:
Here are the .fx files:
softparticle.fx
depth.fx
custom sky shader
And the way it's created:
Best regards!

How it looks like with default acknex sky and without fog:
Default acknex sky + fog, what are those while lines on the edges?
Custom sky shader (thanks to txesmi
) and without fog:

Code:

texture mtlSkin1;
samplerCUBE mtlSkin1SamplerCUBE = sampler_state { Texture = <mtlSkin1>; Mipfilter = NONE; Minfilter = NONE; Magfilter = NONE; };

out float4 outPos: POSITION,

outWorld = mul( inPos, matWorld );
}
float4 SkyPS (
in float4 inWorld: TEXCOORD1 ) : COLOR0
{
float3 Dir = normalize ( inWorld.xyz - vecViewPos.xyz );
float4 Color0 = texCUBE ( mtlSkin1SamplerCUBE, Dir );
Color0.a = 1.0f;
float Fog = 1.0f - pow ( Dir.y, vecSkill1.x );
Color0.rgb = lerp ( Color0.rgb, vecFogColor.rgb, Fog );
return Color0;
}

pass p0
{
CullMode = None;

And the way it's created:
Code:
sky_ent = ent_createlayer(SPHERE_MDL, SHOW | SKY | CUBE, 1); vec_fill(&sky_ent->scale_x, (camera->clip_far * 0.99) / 16); sky_ent->material = mtl_create(); sky_ent->material->skin1 = bmap_create(sky_bbox_tga); bmap_to_cubemap(sky_ent->material->skin1); effect_load(sky_ent->material, "mtl_sky.fx"); sky_ent->material->skill1 = floatv(1.6);
Best regards!
White lines are still there, and about event and flags for the sky material, this is how I've done it:
I am out of the run. No idea what can be happening.
At least not with acknex,
