Yes, the 'world building way' is limited so that from every material file, only a single material is used. > separate the materials in several files, there is no way to tell which > material slots correspond to the right material files. Also, I Build mode should show an input box for every slot, so you can assign them correctly there. > couldn't see any textures... is uploading them enough? Unfortunately not -- the Linden / OpenSim asset system works with UUIDs, so in order for the materials to point to the textures, they must use the UUIDs to refer to them. The UUIDs are created on the server when you upload the textures. > Finally, I tried to do this another way. I wrote an ogre scene file > that contained only my mesh object as a node.

Did you publish the scene on the server? The scene import tool in Naali works so that it first loads the dotscene to Ogre in the viewer directly, without using the asset system. This way the ogre way of referring to the materials and textures just with filenames works. But this step is only a local preview of the scenepart imported -- nothing is uploaded to the server yet. Then you have to fill in the form for publishing, enter the target region name at least (it doesn't default to current region automagically now, should I guess), and press the publish button. It then makes a zip of the scene + all meshes, materials and textures referred in it. That zip is sent to server with http, and processed there so that it creates Opensim assets of all the data and puts the resulting UUIDs as references to the right places. > about some missing material UUIDs... oh, and when I restart the > viewer, i stop seing the attached materials again, either with the > load scene trick and the normal world building way. If this was also with the dotscene publishing, getting the server log would be helpful to know what exactly happened there with the material asset creation etc. The 'blender way' Cecil referred to is this same dotscene zip upload route. With the more integrated b2rex tool with the difference that there the UUIDs for scene object instantiations, meshes and textures are created in Blender already, so you can non-destructively upgrade an already uploaded scene on the server with a new export from Blender (e.g. if you just move an object, it only changes the position of that object, so scripts etc. attached to it stay and no new assets are created). > Edgar I hope this helped, please tell more of how things went ~Toni -- http://groups.google.com/group/realxtend http://www.realxtend.org
