Hi all,
when I replace a TextureMaterial with another TextureMaterial that has the same lightPicker set as the old TextureMaterial, the Mesh is black during a couple of frames.
When I replace the TextureMaterial with a new one that hasn’t a lightPicker set, no problems occur.
As far as I see, setting a lightPicker is the only way to get non-default lighting on a TextureMaterial?
Thanks in advance 
var txt:BitmapTexture = new BitmapTexture(bm);
var mat:TextureMaterial = new TextureMaterial(txt);
mat.specular = 0.7;
mat.gloss = 400;
mat.mipmap = false;
//mat.lightPicker = oldTxt.lightPicker;
msh.material = mat;
