Cartoon-Shader no texture support?

[Anon]

So i got all excited with built-in toon support and demo shader, loaded my model... but looks like a textured model isnt supported?
With the shader its white,
without shader only the outline works
PS. I have zero shader programming experience

[ThomasEgi]

the toon shader sample was not build with texture-support in mind, so it has no support for texture. it can be added by modifying the shaderfile itself.
thought this has been discussed on the forum quite some times already. for example here http://www.panda3d.org/phpbb2/viewtopic.php?t=6929
using the serach function might bring up lot more results.
note: you can do cartoon-inking even without shaders,for example as workaround for veryveryvery old graficcards.

Toon effect without shader:

The black colour doesnt shade right.

heres my model:

I think the problem is in my model, because:

Hm, does your model have vertex normals?

I have uploaded the model.
You can find the download link in my previous post.

I guess built-in toon shading doesnt change specularity.
So i changed specular to 0 in Blender:

Still not bad. But outline doesnt work. If I press outline too much I get these black lines from top and right of the window. Those are present with the default panda model, too.

Like i said ive uploaded my model:

Its just a placeholder. But its the same for my other models...

yes, your zip file has broken.
Well, I got black lines from top right of window too if I outline too much. I think it's the way shader runs. This part should not be the problem.

It's a conundrum, and there has been a similar bug report about this:

[sunbull]

Anon, you should alter the texture by .jpg or some other. When using the .png you can mention that the render-to-texture has an error resault. I guess Toon doesnt support Alpha channel. Maybe your other models are the same.

here is the resault:

Thanks for the help.
But isnt this a bug then? I checked in GIMP and there wasn't any alpha value.
JPG is lossy, BMPs are big, and PNGs are small, like few kbytes for few-color images like this anyway. So I would really like to use PNGs.

[sunbull]

So that you should use rgb mode in your model's texture.

Add this line to you .egg file, after the line "panda.png":

[Anon]

Ah, it's finally solved...

I will probably modify the chicken script. I would still call this a 'bug'.

[sunbull]

But you are using png without alpha channel...
I cant understand that. isnt it a contrary way to original intention of png...
actually you can contral the compression rate of jpg. isnt it better?

No, png isn't used only for the transparency. Jpg format has lossy compression. Even if you set it to 100% it is still noticeable, at least for me ( and in that case also big in filesize). Png uses lossless compression methods, so its bigger, but the image doesnt change visually. Png is of course bigger than a 75% jpg but its smaller than bmp ( which can be compressed but I have never seen one). Also png is really small if you use few colours.
I know that a jpg textured model cant be so bad visually, but why not use png if its almost the same size in my case?
Also all the commercial games I have seen which dont use their own format use png or tga. Havent seen any with jpg (but maybe its the lisencing, I dont know).

[sunbull]

I really learnt a lot from that. Thank you!
