in short:
is there a way to make vertex-shading and simultanously overlayed textures visible in a vrml-browser (as it works within lightscape)?

i hope someone can help me a bit, as i didn't find any ressources dealing with this topic and had to learn all by myself, how to avoid problems with vrml-export etc...

now the long story

here is a vrml-example i made last year:

http://www.photonensturm.de/web/radi...l/smallsun.zip

(to view, you must unzip all files into the same directory and open the *.wrl file with a vrml-browser)

my workflow was as follows: export solution to vrml, translate to vrml2 with vrml1tovrml2, then edit some of the material properties, otherwise they are not shown properly...
then i realised that vertex shading and overlayed textures are not possible within vrml (maybe there is a way, but i don't know).
so either the shaded surfaces are visible without textures or you see the rough texture. i didn't manage to get them both working. maybe it has something to do with the conversion from vrml1tovrml2, because a fresh converted vrml2 file still has to be edited a bit in order to make it look good. i discovered that all "material" nodes have to be deleted, otherwise the surfaces reflect the head-light. but maybe this is also the problem why the textures are not shown properly.

to override all this i mostly used meshtotexture for my vrml-example. this way i could delete all unnecessary mesh and make the model smaller. but it was very frustrating to convert each single side of the building into one texture. i had to select surfaces very carefully and save every time i had created a new texture...

(if someone is interested, i made the same example with skylight only

http://www.photonensturm.de/web/radi...l/smallsky.zip

well, this method works well with orthogonal models. but with more complex models it becomes difficult to find right projection-planes for the textures etc...

in my latest models i still convert the main surfaces to textures. but i cannot do this with each surface, so smaller surfaces that normally should be textured don't show the texture within vrml.
has anyone an idea or any tips? it would really be a great help!

thank you very much in advance!
