I try but I am stuck at step 7. I can not export the other files, I managed to open the GMDC file in the plugin view but there is no way I can export the GMND, I can extract with a right click in the ressource list but I suppose it is not the same.
Then I read Inge Jones's post and I am wondering if I should have done something different as I have a recent version of simPE.
Thanks

Hello,

I downloaded this bike on MTS: http://www.modthesims.info/download.php?t=260676 (I also downloaded the adult version).

So now I am looking for a bike helmet wearable by all the sims including children (both genders). I have looked for it on a  lot of websites but apparently it does not exist.
I put my request in the hair section but it can be an accessory or an object (why not ?).

I thought about making it myself but my skills are limited to recolor with BodyShop or simPE but I think this requires meshing.

Thank for your help
