Terrain decal

I tried different variations of alpha things in material but how can i ged rid of hard edges and make it more smooth, like my decal texture is ?

 

texture0="abstract::decal.dds"

blend=0

depthmask=1

overlay=0

zsort=0

cullface=1

castshadows=1

specular=0.0

gloss=0.25

bumpscale=1.0

shader="abstract::mesh_diffuse.vert","abstract::mesh_diffuse_alphatest.frag"

shadowshader="abstract::mesh_shadow.vert",""

 

this is my old material ...

thanks ;-)

Use blend=1 instead of the alpha test shader. Also set zsort and overlay to 1.

sometimes, i can see a terrain through my decal, how can i avoid that ? because sometimes, visual terrain is a little bit different from physic terrain.

Raise the decal by a tiny amount, like the road is, and use the overlay setting.

I did it, but still, this problem is there. Decal is aligned to terrain grid, so Terrain shouldn't be seen though decal.

texture0="abstract::decal.dds"
blend=1
depthtest=1
overlay=1
zsort=1
castshadows=0
shader="abstract::mesh_diffuse.vert","abstract::mesh_diffuse_alphablend.frag"
shadowshader="abstract::mesh_shadow.vert",""

 

decal is 32x32 quads aligned to terrain grid, terrain is 1 meter per tile, decal is 4x4 meters.

I am using TerrainElevation, so it should be ok, but it isn't

 

So, looks like, TerrainElevation is not accurate, returns sometimes different values or visual side of terrain is inaccurate.

 

where is a problem ?

try this:

 

texture0="abstract::decal.dds"
blend=1
depthtest=1
overlay=1
zsort=1
castshadows=0
shader="abstract::mesh_diffuse.vert","abstract::mesh_diffuse.frag"

try this:

 

texture0="abstract::decal.dds"
blend=1
depthtest=1
overlay=1
zsort=1
castshadows=0
shader="abstract::mesh_diffuse.vert","abstract::mesh_diffuse.frag"
