Texturing At Runtime

[ortsa]

Hi everyone,

What i need is to be able to load a model and then be able to texture it at runtime, and be able to change the textures of certain elements of the 3d model at the click of a button.

Im not too sure about how to do this, so i thought i may aswell ask for your help.

Thanks A Lot.

What i need is to be able to load a model and then be able to texture it at runtime

examples/01.HelloWorld/main.cpp

Code: Select all

node->setMaterialTexture( 0, driver->getTexture("../../media/sydney.bmp") );

and be able to change the textures of certain elements of the 3d model at the click of a button.

A particular model - or more specifically a particular C/SMeshBuffer - can only have one material at a time, so you'll have to load multiple models and/or create multiple SMeshBuffers in order to achieve this.

the problem with setMaterialTexture is that it sets the texture for all mesh buffers...
if you have (for example) 3 mesh buffers each with a different texture and you use setMaterialTexture on the node than all 3 mesh buffers get the same texture...
this also belongs to setMaterialFlag and setMaterialType...

but I added new functions with my IrrExtesnions so you now can set/get the texture, flags and type for each mesh buffer easily:
get/set material for each mesh buffer

with this you can now, for example, make only a part of the node transparent and not the whole node...
of course you need to know which mesh buffer you want to change then...
