normal not obvious

Virion · Post by **Virion** » Fri Feb 16, 2007 1:57 pm

i've made a brick texture and a normal map for it.
i made a test scene with irredit, then i tested it with irrlicht renderer. i found that the normal bump is not obvious... it is just like adding outlines to every single brick. lol

any suggestions?

Have you added a light?

i got 2 light sources. one at the front, one at the side. oh maybe it's too bright?

i've reduced to 1 light source, and reduce the radius of light to 50. but it still look like the same.

i realised that there are some errors when i apply normal map in irredit:

Error: Normal map renderer only supports vertices of type EVT_TANGENTS
Error: Normal map renderer only supports vertices of type EVT_TANGENTS
Error: Normal map renderer only supports vertices of type EVT_TANGENTS

what is that mean?

It means you haven't created a mesh with the correct tangents. Look at the Per Pixel Lighting example (#6 I believe, maybe #4) and look at the roommesh, room, and tangentmesh pointers.

how to create mesh with the correct tangents? not very understand.

You mean this?:

Code: Select all

scene::IMesh* tangentMesh = smgr->getMeshManipulator()->createMeshWithTangents(
			roomMesh->getMesh(0));
			
		room = smgr->addMeshSceneNode(tangentMesh);
		room->setMaterialTexture(0,	colorMap);
		room->setMaterialTexture(1,	normalMap);
		room->getMaterial(0).EmissiveColor.set(0,0,0,0);
		room->setMaterialFlag(video::EMF_FOG_ENABLE, true);
		room->setMaterialType(video::EMT_PARALLAX_MAP_SOLID); 
		room->getMaterial(0).MaterialTypeParam = 0.02f; // adjust height for parallax effect
		// drop mesh because we created it with a create.. call.
		tangentMesh->drop();
	}

ok getting it working now. but this is fully done in dev-c++(disnt use irredit at all). what i want to ask is, can this be done in irredit only? because i am not the programmer of my project. i am just an artist and i am using irredit to create my game scene.
