[source]selfillum on alpha texture?

[Steppenwolf]

Anyone know how this works? No matter what i try i cant get both things to work at the same time.

I remember that i had the same problem when i worked for Insurgency and i remember that i figured it out eventualy (i created a glowing aimpoint for one of the weapons that was visible on night maps). They seem to have removed that lense tho so i cant look there how i did it

[Pampers]

what have you tried to do so far?

[Steppenwolf]

Got it working now. You need two alphachannels. One in the diffuse texture and the other in the specular texture. The later will be used for the selfillum info. The stupid thing is that this seems to override the vertexlighting on a model (selfillum is set to 50% but still each plane has the same brighness now). So its not really what i tried to accomplish (which is kickass foliage) :/

My vmt looks like this:

"VertexLitGeneric"

{

	"$basetexture" "Cherrytree/cherryleafes01"

	"$envmapmask" "Cherrytree/cherryleafes01_spec"

	"$envmap" "env_cubemap" 

	"$alphatest" 1

	"$nocull" 1

	"$model" 1

	"$surfaceprop" "foliage"

	"$selfillum_envmapmask_alpha" 1


}

oops sorry for your message step; i wanted to edit my post, and i forgot i was a moderator ;xxxx - kokos

Very cool tree , what i wonder actually... is how you managed to have a good resolution like that for your tree leaves ? When i use the render to texture option in tree[d], it seems to be stuck to 512*512, and always give me dirty pngs

lol Kokos @fucking up my post

Here is the picture again for the people who missed it:

On the left the tree with only diffuse and alpha, on the right the same tree with selfillum added after i got it to work properly (probably needs a little tweaking because the shadow areas might be a little too bright now).

That is a 512x512 texture for the leafs. However the single leaf that i used for the render in tree[d] was custom made. And i did some photoshopping afterwards to the colors and to the masking to give it a little more depth.

ah cool, thats a neat trick

[ultradr3mer]

if you dont need to brighten only spechial parts you can use unlitgeneric shader

but in case u use it on model, you need to set "$model 1", if you dont it wont render.

cool tree!

Another thing you can do to make the lighting look nice is point all the normals of the alpha planes upwards, so every vertex gets the same lighting.

That's an interesting idea! There is also an option in OB hammer to ignore the surface normals for lighting (possibly does the same thing)

the normals pointing up trick is what i used on wanda:

it come swith its very own set of problems but it is a convent quick solution i guess

with the texture you have thee with ao painted in and all this could be used to a much better effect than what i have in my map

[KoKo5oVaR]

The solution for trees i found with unity is just to paint your vertexcolors in max before exporting the model; (painting shadows by selecting vertices with the soft selection tool to have something really smooth) but i'm not sure if it's even possible to export vertexcolors in source

[Warby]

i am sure it is not possible !
