Transparent matrial confuse me , need help please

Hi all

i want to blend sydney mesh with my background ,so i do the following

Code: Select all

IAnimatedMesh* mesh;                        
mesh = irrSceneMgr->getMesh("media/sydney.md2");                         
IAnimatedMeshSceneNode* node; 
node = irrSceneMgr->addAnimatedMeshSceneNode(mesh,0,666);
node->setMaterialType(EMT_TRANSPARENT_ALPHA_CHANNEL);
node->setMaterialFlag(EMF_LIGHTING, false);
node->setFrameLoop(0, 310);
node->setMaterialTexture( 0, irrVideo->getTexture("media/sydney.bmp"));
node->getMaterial(0).AmbientColor.setAlpha(255/2);
node->getMaterial(0).DiffuseColor.setAlpha(255/2);

but when run the program it renders without Transparent, did i make something wrong.

You need texture with alpha channel. Replace sydney.bmp with particle.bmp just for test and you will see that it is transparent now.

Do you really thing that this stuff is of advanced level? It fits better in the Beginner Forums.

I agree, but please keep-in-mind that beginner to some can be advance to others... for example Algebra can be considered "advance math" to some, its all a matter of perspective.

yes , i think that i choosed the right one, because there are many ideas and effects that could be
applied by this code if it works well,for example i can Fade in ,ore out my mesh in my scene,
do you think fading is advanced level or not.

by the way if i were you, i will answer and try to help instead of point the user to the correct
forum.

Forum sections are done to be respected. This way advanced users who does not want to read the beginner forums and prefer to concentrate on discussions about advanced stuff do not really have to.

Well, the subject for advanced forum says "If you are an advanced programmer", thus depends on personal opinion of the poster. Furthermore it says "no questions on C++ programming" which was respected in this thread, and it says "no questions which have been answered in FAQ", which I did not check, yet. But I guess the thread is conforming to the current restrictions of this forum. You might want to change those, but right now I would not object this thread. I would however appreciate to have this kind of questions in beginner's forum, too.

i see that you are the ONLY one here in this forum who insist on your opinion,so i have no more words to say for you.
