exporting to .HTML scales object wrong

23 April 2015 12:10
im working on a model for cardiosurgery. I tried to export my file to .html and it works, but the scale and the object material are doing some strange transformations. Is there a setting that i missed?

Hello and welcome!

If you press f12, and see the console you may see some warnings and errors. So here we see:

1. B4W EXPORT ERROR: Incomplete mesh "Circle" No UV in mesh with UV-textured material. Material: "Arterie".

"Circle" is an arterie and the material uses empty texture, but this texture has UV mapping. So the engine tries to find UV coordinates and fails - because there aren't any. And it makes it pinkish "errorish" material instead of existed one - to show that here are some errors. So I recommend just to delete this texture because it doesn't seem to do anything

2. B4W EXPORT ERROR: The "Armature" armature modifier has no armature object or it is not exported. Modifier removed.

Arterie has an empty armature modifier - just delete this modifier.

3. B4W EXPORT WARNING: Missing active camera or wrong active camera object

You doesn't have any cam in the scene - so the engine just makes default one. I recommend to add a camera because you can control its parameters and position in that case)

B4W WARN: non-uniform scale for object Sphere.001
B4W WARN: non-uniform scale for object Circle.003
B4W WARN: non-uniform scale for object Circle.002
B4W WARN: non-uniform scale for object Circle.001

Aand this is it, As said here (Transform > Scale), all 3 components (x, y, z) should be the same. You can select those objects, press Ctrl+A ->Apply scale, or you can select "Apply scale" in Blend4Web part of Object settings. Also select here "Apply Modifiers" too because now everything exports without subsurf

One more thing: I strongly recommend deleting all those lamps exept one. Lamps are very heavy things and you can do it all just using one sun lamp and adding some environment lighting.

Here I made everything said above :)
