Strumpy vert_surf error

Unity Engine
1

Hi
Unity 4
I put together a diffuse, normal, specular shader with the strumpy editor and get this warning from the console:

Shader warning in ‘Wolf’: Program ‘vert_surf’, ‘vert’: output parameter ‘o’ not completely initialized (compiling for d3d11_9x) at line 86

In the log I get this on various lines.
Shader warning in ‘Wolf’: Program ‘vert_surf’, implicit truncation of vector type (compiling for d3d11_9x) at line 16

Opening the warning itself opens this script:

Shader "Wolf"
{
	Properties 
	{
_diffuse("_diffuse", 2D) = "black" {}
_normal("_normal", 2D) = "black" {}
_specular("_specular", 2D) = "black" {}
_glossiness("_glossiness", Range(0,1) ) = 0.5
_specularlevel("_specularlevel", Range(0,1) ) = 0.5

	}

Actually on line 86 there is not a whole lot happening but I read here that the line indication can be off by quite a bit :slight_smile:

On these forums someone suggested filling in the “o” s but where and with what I couldn’t tell. There is a bunch at the bottom but I have no idea how to handle them.

Any help appreciated and thanks in advance.
Cheers

I’m not sure it’s upgraded to use 4.0 yet.

Thanks hippocoder,

The error would then make sense.
I mean if I actually knew how to code, then it would make sense :slight_smile:

I’m using Unity 4.0 Pro and attempting a simple emissive shader. No matter what I do, I can’t see to get the emission to affect static lightmaps. When switching to the basic unity self illumination shaders, it works as expected. Help!

I found that I couldn’t acheive shadows with the strumpy shader so I left it. This doesnt solve your problem but I found the standard shaders in unity 4 do about everything I need atm.

Hey quantum i ran into that problem a week or so ago, one thing you need to make sure of is that you name your shader correctly for example if it’s an self illum shader make the name “Self-illumin\yourshadernamehere” because Beast(the program that does light mapping) looks for keywords in the shader name once that is done and you save the shader it will be put into the “self illum” tab in the shader drop down menu in unity

Try sticking
UNITY_INITIALIZE_OUTPUT(Input,o);
in as the first line of the vertex shader.
