[Shaders reflections changes ?]

Edit: Josh I think calculation for reflective cubemap is wrong.

 

line 63 and 64 :

 

 //reflectdir.y *= -1.0; //no need
cubecoord = reflect(cubecoord,reflectdir); //reflect cubecoord by reflectdir not the other way around

[Seeding random generator]

Yeah, I don't think you can seed LE's RNG using this.

[Seeding random generator]

LE really needs to expose some way to do a real seeding of it's random numbers

 

Aha..

math.randomseed(Time:Millisecs()) 

always gives you randoms even in Start().

 

Seems like Time:Millisecs() returns the system time in milliseconds, not apptime.

http://www.leadwerks.com/werkspace/page/api-reference/_/time/timemillisecs-r496

 

So there you go.. proper way

[Seeding random generator]

You can use this unless you're doing randoms before rendering starts. There will be tiny variations in rendering speed.

first 5 will always be the same since GetSpeed is then 0 after first frame you will have randoms.

 

function Script:UpdateWorld()
   math.randomseed(Time:GetSpeed()*43758.5453)
   for x=0,4,1
   do
       System:Print(math.random())
   end
   System:Print(" ---- ")
end

[Can i render a model that is not in camaera range ?]

No. But you can increase the camera range and have no occlusion culling.

[Official Leadwerks Exporter for Blender]

.fbx looks fine when imported to LE. (when given a material with skinning shaders)

.mdl file looks wierd on the animation yes.

[Dissolve shader]

Just add this line at the bottom of the shader to burn red.

 

if (NoiseV<InvAlpha+0.025) fragData2 = vec4(1.0,0.0,0.0,specular);

 

0.025 is the width of the burn, 1.0,0.0,0.0,0.0 is the color.

 

EDIT: it's already in there in the zips above, however after the decal update, materialflags were moved.

[weird rainbow effects in distance]

Maybe related, but terrain gets really low quality when activating water.

Load up 08-Terrain.map and just turn water on/off to see the change.

[Day and Night Cycle shader]

This generates clouds in the DayNight.shader

if you change ctime to -ctime they go the opposite way.

 

vec3 cloud2(float cloudheight,float scale)
{
   vec2 p=vec2(vp.zx/(vp.y))*cloudheight;
   vec3 c = vec3(.0, .0, .2);
   c.rgb += vec3(.6, .6, .8) * cloud(p*.3+ctime*.0002,scale)*.5;
   c.gbr += vec3(.8, .8, 1.) * cloud(p*.2+ctime*.0002,scale)*.1;
   c.grb += vec3(1., 1., 1.) * cloud(p*.1+ctime*.0002,scale)*1.;
   return c.rrr;
}

Yes, I think I did a blog aswell.

[Still waiting on substance support...]

Here is a nice cull script I've used alot

 

    --optimize scene place objects in viewrange based on their aabb radius.
   for i=0,world:CountEntities()-1 do
    if world:GetEntity(i):GetClass()==Object.ModelClass then
		    local aabb=world:GetEntity(i):GetAABB(Entity.GlobalAABB)
               if         aabb and aabb.radius < .1 then world:GetEntity(i):SetViewRange(0)
               elseif     aabb and aabb.radius < 1 then world:GetEntity(i):SetViewRange(1)
               elseif     aabb and aabb.radius < 10 then world:GetEntity(i):SetViewRange(2)
               elseif     aabb and aabb.radius < 20 then world:GetEntity(i):SetViewRange(3)
               else     world:GetEntity(i):SetViewRange(4) end
    end
   end

[What are you working on :]

Realtime reflections using dual parabolic env shader (2 extra cameras with the new render to texture)

 

 

But there is a caveat..., since I can't hide the reflection object before the render to texture, I have to place the cameras inside the sphere.

So.. it will only work for spheres. Arbitrary geometry would self reflect.

[Custom Shader not working]

Decals triggered a change in the channels

[Ragdolls disappearing]

Found my project, just move the skin with the torso like each loop:

 

self.skin:SetPosition(self.torso:GetPosition()) --keep AABB inplace.

[Ragdolls disappearing]

ok, I seem to remember that fixed my ragdolls, but I might be wrong. Tru turning off occlusion culling aswell.

[Ragdolls disappearing]

You have to update the AABB each loop.

      --Update the model local and global AABBs so the renderer keeps proper track of it
      model:UpdateAABB(Entity.LocalAABB)
      model:UpdateAABB(Entity.GlobalAABB)

[Decals Offset from Map Origin + The Position Of The Decal]

07-AI map from MyGame shows nothing when shooting.

[Flat shading]

You can recalculate normals with a geometry shader as flat like this: (will override all mesh smoothing)

 

vec3 edge1 = vertex_position[1].xyz-vertex_position[0].xyz;
vec3 edge2 = vertex_position[2].xyz-vertex_position[0].xyz;
mat4 nm=transpose((cameramatrix));
vec3 faceNorm = mat3(nm) * normalize(cross(edge2,edge1));

Hi, you should be able to use these to detect this:
