Changing MaterialType does not work

pippy3 · Post by **pippy3** » Thu Mar 31, 2011 2:55 am

I want to change

			mesh->getMesh()->getMesh(0)->getMeshBuffer (0)->getMaterial ().MaterialType = video::EMT_TRANSPARENT_ADD_COLOR;

to

Code: Select all

			mesh->getMesh()->getMesh(0)->getMeshBuffer (0)->getMaterial ().MaterialType = video::EMT_SOLID;

But it stays the same after I modify it. Others have had this issue too.

Is there a work around, or am I doing something stupid?

have you tried passing n (mateiral index) as the param for get material?

ha! didn't expect for a reply that quick that fixed the problem. Yes it did

Code: Select all

if(!seethrough){
	mesh->getMaterial (0).MaterialType = video::EMT_SOLID;
	mesh->getMaterial (1).MaterialType = video::EMT_SOLID;
} else {
	mesh->getMaterial (0).MaterialType = video::EMT_TRANSPARENT_ADD_COLOR;
	mesh->getMaterial (1).MaterialType = video::EMT_TRANSPARENT_ADD_COLOR;
}

welcome.

remember to always read the API for any little params you are passing wrong/not passing at all.

and also check for const stuff.. to make sure you are passing const correct params or getting the right references you need.

You can also alter the material type at ISceneNode level that overrides the meshbuffer materials and uses a single call that does all the process
