setTexture question

[evilduck41]

for bgfx::setTexture, what is the texture unit _stage parameter? If I have two uniform values for each texture sent to a shader does each also have to have its own _stage value?

void setTexture(uint8_t _stage, UniformHandle _sampler, TextureHandle _handle,...

You could think it this way: _stage is slot where _handle is bound, and _sampler is name of sampler to sample texture in _stage slot.
