[no bug]removeTexture OPENGL

[CiRiuS2]

First as allway sorry about my english, i will try explain me. I have a function like this:

Code: Select all

void onFinishLoading(...)
{

[...]

      IImage *im = driver->createImageFromData(irr::video::ECF_A8R8G8B8 ,dimension2d<u32>(WIDTH,HEIGHT),buffer,true,true);
		ITexture *res = driver->findTexture("resultado");
		if(res!=0)
		{
			driver->removeTexture(res);
		}
		ITexture *txt = driver->addTexture("resultado",im);

[...]

}

If the driver is not EDT_OPENGL the code works fine. If the driver is EDT_OPENGL, the first time i call the function the texture is added correctly, but the second time when i remove the texture, something is wrong with the method removeTexture.

The pointer txt gets a white texture . This don't happen with EDT_DIRECT3D9, EDT_SOFTWARE, ...

Ok forget this, magically today is working with opengl.

Just gonna bump this to say that I've been running into this same bug. removeTexture() is causing the same white texture issue for me.

I finally fixed it by doing:

Code: Select all

driver->setMaterial(video::SMaterial());
driver->removeTexture(texture);

I got that fix from this thread:

This can happen. This happens when you remove the texture and update it.
Solution:

if you remove the texture call SetMaterial before.

Code: Select all

params->driver->setMaterial(video::SMaterial());
params->driver->removeTexture(texture);

This insane workarounds in Irrlicht or OpenGL is what drives everybody mad.
