yes i have shadows in that grey place but panda3d changed it to grey color
I think that youāll find that itās not a grey colour, as such, but the background showing through. That is, I suspect that if you were to change the background colour to green, the relevant parts of the model would seem to turn green, too.
This suggests that your shadows are ending up in the alpha channel somehow.
that is right i did like that
should i remove it
Ah, yes, that does explain itāyou are indeed writing to the alpha channel, and as a result the area in question comes out as semi-transparent!
(Could you perhaps have it modify the the brightness of the colour, perhaps via a multiplication? Iām not sure that such a thing would be preserved by YABEE, but it might be worth a shot.)
i didnāt understand you when you said modify the brightness of the color
The intensity of it. This might be as simple as multiplying the red, green, and blue channels all by a value between zero and one.
you mean in blender or directly on panda?
In Blender, where youāre currently affecting the alpha.
I would guess just the ābase colourā.
A quick question, as Iām not sure of whether weāve established this: Does the animation work when exported this way? I want to check that this approach is worth pursuing.
what do i have to do whith the base color link it to alpha or dislinking it to color.
yes the animation works like that
Ah, excellent! Iām glad to read that we got it working in some way! 
Iām guessing somewhat here, since I donāt know exactly what youāre doing with each element. However, that said, you indicated that you were using some input to provide shadowing. Iād suggest taking that, using a mathematical node to multiply it be the colour, and then feeding the result into the ābase colourā input.
i think i need to change the whole hair maybe.
