Only the first object is transparent

[saigumi]

cd I've seen this strange problem. My first object gets created and textured fine. The second instance to use the same texture causes the transprency to be dropped.

Any Ideas?

Code: Select all

	irr::video::SColor transparent = irr::video::SColor(0, 255, 0, 255);
	node = environment->smgr->addTestSceneNode(1,0,-1,Start);
	irr::video::ITexture* image1 = environment->driver->getTexture("explosion.bmp");
	environment->smgr->getVideoDriver()->makeColorKeyTexture(image1, transparent);
	node->setMaterialTexture(0,image1);
	node->getMaterial(0).BackfaceCulling = false; //will make all polygoons to be doublesided 
	node->setMaterialType(irr::video::EMT_TRANSPARENT_ALPHA_CHANNEL); 

First one:

which driver?

[saigumi]

DirectX 8 + 9.
OpenGL does it right, but the material that isn't transparent is very faded.
Software doesn't do transparency at all.

OpenGL does it right, but the material that isn't transparent is very faded.

Is it faded for all of them under OGL, or just anything past the first?

[saigumi]

All of them are faded when I use the OpenGL driver. I've been trying to dig through why but haven't found anything yet.

Found the problem.

Each time I create the texture for each object, I applied the color key. Since the color key had already been applied, the color key transparency gets borked and fills in black.

I fixed it by loading all my textures once and applying the color key. Then, the each object just loads the texture out of memory.
