I now have a multitextured mesh on screen created with my exporter. I also have it animating. One problem is as soon as I applied the animation keys to a once mulittextured static model, no sooner is it an animation model it stops being multitextured.

Have I done something wrong, or is this one of the limitations?

Also does this limitation extend only to each animated mesh component (eg. the arm or leg)?

I'm not talking about a skin model here by the way, just animated meshes.

thanks :)

I use multitexturing on animated models. So it's not a limitation, you must simply be doing something wrong. Specifically, if you are using heirarchy animation (ie. parts are separate objects) you probably are only applying the multitexturing to the root object. You need to loop through all the child objects and apply multitexturing.

Hi Again,

It's very odd. If you delete the animation bit from this code chunk below ('keys' & 'anim' section), it starts being a multimaterial mesh again. Any ideas from my code where I'm going wrong?

Remember I'm just animating objects and not a soft skin model.

thx,

Mike
