when i use
Code: Select all
draw2DImage(driver->getTexture("c:\\image.png"), position2di(x, y), SourceRect, 0, SColor(255, 255, 255), true);
to draw the png image.the image is my need.
then I want to display a png image as a mesh texture.
so i write
Code: Select all
node->setMaterialTexture(0,driver->getTexture("c:\\image.png"));
but i get a different color image texture.
how can i get the correct png image as a mesh texture?
Thanks

It would help to see the different colors. So please upload screenshots somewhere (e.g. sourceforge bug tracker). Maybe it's just a missing lighting disable?

Did you change the material type to one supporting alpha textures? Otherwise only RGB is rendered.

EMT_TRANSPARENT_ALPHA_CHANNEL is the one you want. But since your png alpha channel only has values <=127 the default settings won't render the image at all. You have to set MaterialTypeParam to 0.001f or something like that.
